After what feels like forever we finally started real works. We’ve done lots to the plot, tree clearance, root removal, digging out beds, planting, etc. but little to da bungalow itself. We held off stripping out ‘til we were sure the project was viable, which was über cautious but that’s us. Selection of timber frame supplier wasn’t straightforward. It came down to a local-ish company (ETE) who supply a panelised frame for manual erection on site or stick built on site under the supervision of an SE. Most frame companies require crane assembly, which we can’t have due to overhead wires. But once we felt we were in the right place, planning, party wall agreements, demolition survey, site insurance, timber frame supplier, the main peeps to help us build, etc. then we got down to it. That initially meant selling/giving away the kitchen, a fireplace, the conservatory, the UPVC windows and door, an electric fire and even a garage. I had intended to do more stripping out before the cavalry arrived, but there was always a more important task: digging test holes for the structural engineer (needed for the foundation design, so vital); getting the gas meter removed/capped off and the pipe cut of at the verge annoyingly costing £1,700 (not safe to have gas on site in the way, so vital); replacing fence panels including digging out big roots (to keep the neighbours on side, so vital); erecting a shed, with of course a base (to keep those working on site happy, so vital); moving the water supply (to avoid it being trashed by the groundworks, so vital); digging in (by hand) the 10m of electric duct, casting a concrete base for and installing a huge, but apparently necessary, meter kiosk to comply with the DNO requirements, enabling them to charge us £9,500 - ouch - so vital); dismantling the garage (which was in the way and we wanted it to be reused, so vital); and finally, dismantling the conservatory (which was also in the way and we wanted it reused, so, you guessed it, vital). Turns out breaking up concrete by hand is exhausting, but oddly therapeutic, even if you do bend your ancient trusty steel spade. I wonder, have I got so used to digging foundation test holes and digging soakaway test pits and digging out roots and digging in pipes and ducts that I’m actually going to miss digging? Scarily possible! Who needs a mechanical digger when you’ve a mattock from Amazon and a new steel spade from Toolstation? But then the real works start. 34 years ago we built our current house helped massively by Steve the builder, who was a bit older than us. This time round it’s a repeat, as the same Steve is helping us and given that I’m nicely in my 60s and oddly, Steve is still older, it means that none of us are in the first flush of youth. So my theory was that Steve was the brains and I would be the brawn. Wrong. Steve is both it turns out. Monday saw us stripping off roof tiles and after a day on the battens I was wiped. Tuesday saw me on the battens again for half a day stripping the rest of the tiles and then, just to vary things, I then spent some time on the battens stripping off the felt on one face so we could get the chimney down and kick down some ceilings (overboarded lathe and plaster). Whilst we were out on the tiles UK Power Networks, our DNO, dug up the road and put in our underground electric feed. And a quick bit of begging over the phone got the meter moved that afternoon, so we had site power again. Bliss in a coffee cup. So by the end of Tuesday I was pleased with progress but exhausted. On Wednesday we started stripping out walls and we discovered that there was a lot more plasterboard than I first thought. Damn. Pronto plasterboard skip ordered, we estimated that we’d need a 4 yard skip, so to be safe a 6 yard skip was ordered. Which meant we needed easy barrow access so we removed a window and cut a new front door. Wednesday night I went home totally exhausted and less than pleased due to all the newly discovered plasterboard. That night I came to terms with my limitations, so I messaged Steve to suggest he do a 4 day week to give me time to tidy up and recover. He agreed and offered to buy me a pipe and some slippers. (Pic of new door) The skip arrived promptly arrived at 07:30 next morning. There then followed a rabid day of plasterboard removal. Incredible how effective a spade can be indoors when instructions are given to the novice. By the end of the day we’d nearly filled the skip and had just a hallway ceiling left covered in the dreaded plasterboard. I could hardly raise my arms. One of Steve’s endearing features is his sense of humour. One of his most irritating features is his sense of humour. So as I’m on a step up, gritting my teeth and willing my arms up again and again yet another joke prompts the giggles. That was it, hopeless. My giggling got him giggling and progress paused. Priceless. But determination sustained and the skip was filled. Thank goodness for over-ordering. I went home a zombie, but with less energy. Friday and Saturday were tip runs and tidying up, and now on Sunday I sit quietly reflecting on a week that was unbelievably productive, thanks to Steve’s experience. But oh my, it starts again tomorrow. I have no idea if anyone will find these ramblings of interest, but they are, much like digging, remarkably therapeutic too!

Just been reading through my last post from end of May, and thinking how on earth did it take me so long to get to this one 🤣 A lot of blood, sweat, tears and swearing later, and i've finally finished the bathroom, which has exceeded what I imagined i might be able to create, I still keep walking in and thinking, naaa this can't be my bathroom. So another room brought to a close 🙂 Those panels on the wall were actually meant for the living room, sound absorbing panels for the home cinema, but despite having ordered 'Natural' and them looking off white on the internet, they came with a blue tinge to them so wouldn't have gone. When i asked for a refund, they didn't want them back and just sent me the money, so I thought they'd be useful in the bathroom, and have massively dampened the echo in there. Aside from not plastering the sloped ceiling, everything else you see internally i've done myself, including the cabinets, which I really enjoy making, i took woodwork at GCSE but was at school at the time when IT was just getting going and consequently we were all pushed down that route. Walls are painted with F&B Ammonite, and the ceiling is F&B Wevet, mixed by Johnstones Trade Best success? Probably trusting myself to measure 4 times, cut once, and actually get it right for once...The solid oak top on the toilet/sink back, £130 alone that cost me, but it came out bang on! Total cost for everything was just a shade under £4k. Onto my new snug next which is actually well underway, but i'll post another entry when its all done and dusted in a month or two's time!

Da bungalow that is, not us mortals. We carry on sweating in our hi vis. We were pleased with how the timing worked out - planning to demolish during cooler months so all the neighbours will be wrapped up warm indoors away from the dust, plus it’s hard work so cooler temperatures help comfort. So much for that plan with our mini heat wave! Steve took pity on me by leaving me recovery time on Monday and Tuesday. Good news from a site clearing and tidying point of view. It gave me time to kick down the last of the ceilings, mostly while the windows were still in, and then for J to pick out all the lathes for safety and for disposal at our nearby recycling centre (I’m old fashioned, I still call it the tip!). Trevor the trailer was bought for £200 just over a year ago to help clear the mountains of brash from clearing the massive overgrown conifers. Skooby the Skoda was bought as a building vehicle for £700. We now realise that they have paid for themselves many times over in saving in skip costs. If I’d known how much we would be saving we might have bought a car with a working heater, but hindsight is a wonderful thing. Monday afternoon was window removal time! Ben arrived bang on time and had agreed to help us remove the windows, though he’d never done it before either. I was relying on Steve’s knowledge. Shame he wasn’t there. So da bungalow now has a series of holes where windows were. Each neater than the previous one. If you look at them in chronological order you can see evidence of two keen but clueless numpties first hacking out a huge hole, taking forever, graduating in stages to the last one which was beautifully neatly and quickly and efficiently removed. Yet another example of experience being the thing that one acquires just after needing it. So by Tuesday evening we had a clear site, which is incredibly important on such a tight, narrow plot. And then next morning, Steve returned to the job, so progress exploded again. We stripped the felt and battens off, with muggins of course being the idiot hopping round on the battens for two thirds of the day, with the last third being careful removal of some of the roof timbers. Rather disappointingly, we found woodworm everywhere. So my plan to build my hideaway at the bottom of the garden from reclaimed roof timbers has gone. Some of the timbers came away scarily easily. But those that didn’t put up a hell of a fight - they used huge nails in the 1920s it turns out - and this wasn’t ideal as force had to be used in moderation in case of unseen weakness leading to accident or collapse. We were probably overly careful but better safe than sorry. The next two days are a blur of heaving and bracing and sledgehammering and chainsawing. Thank goodness for a decent twin battery Makita saw - saved us no end of time - and my little one handed chainsaw - AKA Lightsaber - was slower but brilliant in places too. It’s oddly satisfying knocking off the little bits of wood that hold up the soffits and facias and rainwear - sending the whole assembly crashing down in a plume of dust. Even more satisfying to push over the block gable - the thump when it hit the ground was like felling a big tree, primevally enjoyable. We did take a break for a site visit from the ground worker. He asked all the right questions which does give confidence, including asking me to gain permission from our neighbours for him to hand dig one shared corner of our frontage to carefully identify where our neighbours services are. He might even have a use for the roof timber mountain we now have! More skip cost saving. All this is punctuated with other strands of the project. They are vital but hard to find the will to divert onto when mid hammering. In that way J and I are working together fantastically. I haven’t the bandwidth to think - I run to keep up with Steve when he’s there - I run to tidy up when he’s not there to get ready for when he will be - I go home a bit too late each day and after a coffee and a discussion about the day I then bath and by the time we’ve eaten it’s bedtime. Buildhub, apart from my weekly therapy session (oh ok, blog writing) is a distant memory. So J does the thinking, I do the grunting. That’s a little bit of an overstatement as in my head, when I stop to access it, is a 3D model of everything and every junction and material and supplier and missing quote and little red flag of issue that might become critical path and hence needs sorting before it does. I can and do flick into ‘principal designer’ mode when needed. But the day to day scheduling and remembering is falling to J. J has given me a little exercise book and my own grown up ball point pen to keep my to do list in. It’s a bit year 5 but it turns out very effective, as long as J remembers to remind me to look at it. Between us we are working incredibly effectively. Long may it continue.

More or less done these two rooms now, which after finishing the bathroom were basically just flooring and decorating, making a bit of furniture and then moving some other furniture I already had which was always destined for the dining room. I’ve got planned some bench seating for the wall side of the dining table to make it more space efficient, but not any time soon. I think this will be the first time, certainly in the last 10 years, where I have no outstanding ‘filler that just needs sanding down and painting’ kind of jobs, everywhere has skirting board which is painted… the little things in life. Everytime I walk in the bungalow and see the French dresser, it just melts my heart, knowing that my late wife would have loved to see it where it is now, we did buy it while she was still alive as they were stopping making it and was perfect for the look we were going for, managed to bag the dining table off eBay from the same range for around £200 I think brand new, and the chairs were ones we had from ikea which I upholstered and painted white to match. I know the plug sockets need covering, managed to locate them just slightly too high! The bookcase is to be backlit with an LED strip light (awaiting Black Friday being the right bugger I am!) and then will be filled with all my books, photo to follow at some point. The hallway has also been redecorated and the floor sanded and reoiled - out of anywhere this small passageway has suffered the most during the works bringing everything in and out, so was nice to get it back to 100% again

(There’s way too much verbage here - sorry - but it reflects the deep spring clean my head needed. Will try to make time for a demolition summary in another post which would be far more useful for others). Each Monday morning, since we started demolition on the 17th of March, at stupid o’clock, I shuffle round the kitchen getting breakfast ready trying to assess how my body is doing, physically. Well, sort of. What actually happens is I slowly get my knees and my back working while bemoaning my stupidity and sheer arrogance in thinking I can do this, convinced that my I am starting the week more tired than the previous Monday. In some ways, almost certainly mentally rather than physically, having a break really takes it out of me. That Monday restart is just simply tough. I could tell myself that this should be the last week of demolition. That this is the last push of the hardest bit of the build. But inside I know that it’s getting towards the end of one phase of a long line of phases each of which I’ll be convinced at the time is the hardest one. But two hours later, at 07:35, I’m on site boiling a kettle waiting for Steve to arrive and my head is in gear and my fatigue is mostly forgotten. My 20 minute meditation, aka the drive to the site, has done its job. I do know I can do this. Anyway, I s’pose I should write a few words about da bungalow. Today, the kitchen gets it! All that’s left now is most of the kitchen walls, composition uncertain, and the dunny. The end of the kitchen nearest the road is, we thought, mostly masonry. The other end is now naked studwork. We left the studwork last week as we suspected it was needed to help the 6m long part timber frame kitchen wall stay up, which is surprising given that this studwork waggles like mad when nudged. So the first task was to take some of the weight off of the 6m wall. We didn’t dare hack the plaster off as we had elsewhere, leaving clean-ish metal mesh to peel off for recycling. Instead we peeled both plaster and mesh together, piling in a heap for me to process later. That worked to start with, but as we made our way along the wall it became clear that there was progressively less strength left in the studs. In the end the wall plate that ran through to the single skin masonry section gave just enough strength to allow us to dismantle the wall in a controlled manner. At one point we did stop and consider just pushing down the middle section, but that could have destabilised adjacent sections and also given the likely state of the soleplate it could have kicked out at the bottom. With next door’s wall only 1,030mm away that felt too close, even with heras fencing between. So we carried on slowly peeling and it became evident that in that middle section, all that remained intact was the two layers of render, topped by a wall plate. Truly scary. Another thing not to share with the neighbours. That done we could then take down the studwork. It was by then wobbly enough to push over safely onto the floor, and a couple of well placed cuts meant it would fall the right way, so push we did. Timber frames falling like that just don’t give that satisfying thump that masonry does, but it does still leave a lot of clearing up of timbers bristling with nail heads. The nail points are, at Steve’s insistence, all hammered over safe. In fact it’s been drummed into me so hard over the last 5 weeks that I now referring to it as ‘Steve-ing the nails’. The wood mountain grows and we learn that the wood man is maxed out and won’t be returning. Would have helped had he told me that last week but that’s life. Back to faceache it is (other social networks are available, but few are as annoying). As we work our way along the kitchen wall towards the road we find a mixture of stuff. Odd bits of plasterboard. Glass fibre insulation as well as the nasty snowy type stuff we’ve had in many other places. Pieces of wood and brick and block and tile just shoved in to repair holes in the render. Satisfied that the remaining masonry end walls (a ‘C’ shape) are safe and stable, we stop for the night. Next day we have rain first thing - the first on the project so far. So we bravely don our hats and coats and bugger off to Cafe Nero to drink coffee and plan. That turns out to be fabulously timely. I have picked up bits and pieces over the years and I’ve recently read tons about building stuff but putting it together in the right order takes Steve’s experience and caffeine. We’ve now got our slightly unusual foundation design, and that enables us to talk over who should do what, when and how. Annoyingly, Steve, with his wealth of experience and such a brilliant, caring and dutiful attitude, would be the perfect ground worker to safely and cost effectively pull our foundations. But he’s semi retired and he hasn’t got the right PI cover and all that. Our party wall agreements (which I was pleased to get as at one point it felt like it might cost us lots and lots of time, money and angst) and our warranty provider (thank you Protek) require fully insured, experienced professional contractors to be used for the foundations. So it isn’t a good idea for me and Steve to do them, even though we’d probably do it more carefully and with less noise and disruption than a ground crew. Sigh. It feels like the litigious nature of our world is killing common sense. In theory the party wall awards required specialist demolition contractors to be used. We did get two quotes, each of which were going to send in a nice big machine with bloody great jaws to eat da bungalow and cause mayhem, and in my view, likely do damage to our neighbours. But we managed to get site insurance (thank you for real this time, Protek) which specifically covered demolition. But if we weren’t bloody minded enough to test and challenge then we could easily have gone with it and ‘done it properly’. Bigger sigh. OK, rant over (for now). The rain stopped and it’s back to site, having lost a couple of hours. We keep telling ourselves that we are not in a rush and it’s not sensible to set targets so of course Steve and I rush to recover the time and hit target for the day - the rest of the kitchen. We first hit single skin red brick, then round the corner, a red brick outer skin and under the internal stud skin, some very old painted plaster from the original outhouse. From the broken earthenware pipes I’ve found digging near there I now believe that this bit was originally the privy. Nearest to the road, so as far from the living rooms as possible, with sections of lead water pipe built in, it conjures up an image of such a different way of life. We find a ‘T’ joint in the lead pipe, simply sweated together - a wonderful illustration of what 100 years have done in plumbing technology terms. By home time we have a short lower section of red brick wall and a twin skinned block section of wall left, both stable but still irritatingly short of the target we didn’t set ourselves. Next day even though we want to finish the kitchen first it’s better to get the dunny down whilst there are two of us. It’s the last chance for a collapse to damage next door so I need Steve on site to blame in case anything happens. The potty is carefully pulled out (will be reinstalled in the house as temporary welfare suite - i.e. a pan, a bucket and for special occasions, a loo roll). The metal lathe and plaster remains only on the inside so is dispatched fairly quickly. Some hammering from a very mobile (but safe) bandstand removes the mostly masonry wall with the window and another sellable catnic is discovered. We now have a trio of them to clean up and sell on faceache. Thence the last studwork to drop. Just like one end of the kitchen, a couple of thought through cuts and a push and it’s down. Just like that. We tidy up, and quickly knock down the last little bit of kitchen wall thats next to a neighbour, and we stand back and contemplate for a mo what isn’t there any more. Steve won’t be back for nearly two weeks, and I think he’s a bit disappointed that he leaves one little corner still standing but he points out that even I can’t cock up taking that down. Personally I think he underestimated my talent in that. So Maundy Thursday sees me bashing plaster off of metal mesh, to get it ready for recycling, and generally clearing up and loading up for a tip run. And something very odd happens. I’m working at the front of the site, nodding at passers by, smiling with my eyes at them (isn’t it weird how a smile gets through a dust mask), when a chap from over the road I’ve not met before comes over. Richard introduces himself and I brace for what I know is coming, as in fairness the dust and noise can’t have been nice for the street. And he hits me with it, and I am taken aback but I try not to show it. He tells me how well we have done and how little disruption, mess and bother there has been. He’s impressed. Wow. Chuffed. We have quite a chat (after all, he will be one of our neighbours and it beats hammering mesh with a spade) and he leaves me rather buoyed up to say the least. Then a chap from three doors down comes and has a chat, just for the neighbourliness of it, and it reinforces how nice a community our new pad will be in. And then (how do I ever get anything done?) Monica stops to say hello and tells me that our demolition ‘is a work of art’. She walks past regularly (I have said hi to her a good few times) and she’s been watching and she is hugely complimentary. If the god of fat, little bald fellas had carefully planned a reward at the end of the demo phase she couldn’t have done better. Tip run done, I then felt I could reward myself by taking down that last corner. Rather than do it top down I stripped out the inner skin (more bloody snowy insulation) and one side to leave a bit of wall to go down with a satisfying thump. Next door have a couple of young lads, the oldest being 9. It struck me that at that age I would have loved pushing a wall down - so a quick convo with his mum, a hastily fitted hard hat and oversize gloves and with mum filming we rock the wall till I can let him give the last push - his grin was a fitting final smile for da bungalow to provide. Bye bye bungalow.

So a quick recap - back in December 2023, what may be my last ever employer decided to ask me to leave. I had mixed feelings about this. I took several weeks to think about next steps and actually get around to writing a father of the bride speech which I'd been putting off. After the wedding in March (a great day and a great speech!) I started to look more seriously for a new job, but being the wrong side of 60 now, the IT industry is not a good place to be looking especially when so many other people have been let go as well. Coming up to the end of May, we sat down and took some tough decisions; we bought a static van on a site about 3 miles from the plot, I stopped looking for a new job, SWMBO did an internal job transfer, we rented out our current house (instead of our original plan to sell up) to three newly qualified doctors (our niece and two others on their first F1 rotations in our local hospital so that worked out well), and we spent 6 weeks decluttering, and moved down SE Cornwall (Kernow) at the end of July. In the last blog entry I ended with a list: Finish ventilation system Finish insulating the GWW Finish backfilling Electrics Floors Walls ASHP and HWC Kitchen Bathrooms The remaining plumbing Outer wall coverings This is how it looks today Finish ventilation system Finish insulating the GWW (Great West Wall) Finish backfilling (on the back burner) Electrics (first fix) Floors (now on the back burner) Walls (En suite partition walls to be done) ASHP and HWC (being done in January) Kitchen (planned for January or February) Bathrooms (temporary loo and basin installed, cold water only, temp bathroom planned for January) The remaining plumbing Outer wall coverings (rendering done, stone cladding starting next week) What I missed off the list, and has taken most of our time: Sound insulation (R35 rockwool and resilient bars) Plasterboarding So a few photos are required I think: MVHR unit in place (since removed as plant room walls have been put in and waiting to be plastered inside) Ventilation distribution boxes and pipes fitted: Plaster board arrived (in May): My cold water manifold has pipes attached for the first time (one now being used for the temporary toilet and basin), no picture of it but just to the right is the hot water equivalent: We powered up the sewage treatment plant for the first time (nearly 4 years after it was first installed!): We started plasterboarding, first a large room into which we moved all our stuff that was in storage so saving a hefty wedge per month on storage fees, and then the much larger and more complex open living area: We took some time off in early October and went sailing for a week, and when we got back some kind fellows had installed some scaffold (first time on this build), and in the following few weeks we had the renderers in thanks to the Kernow weather gods: Meanwhile back inside, we finished plasterboarding the large living area, and during this last week the plastering started (kitchen area first!). We set off a couple of insect smoke bombs as we had a cluster fly infestation and wanted rid before plastering started 🙂 : Dare I add a what's next list 🙂 ? Well, here goes .... Plastering finished in the open plan area this coming week (by others) Remainder of stone cladding arrives and work begins to get the most inaccessible (high) parts put up before the scaffold gets taken away - this means cladding two 7m x 2m wide walls Plumbing pipework ready for ASHP installation Gabion basket and pad for ASHP to be installed on Mist coat and first coat on plaster (SWMBO is at the ready) Begin fitting upstairs UFH Front door being fitted (January) by others Take 3-4 days off for Xmas ASHP installation (January) by others, that will allow for hot water and the downstairs UFH to be available ... Fit a temporary bathroom ... Fit out utility room as temp kitchen ... ... and this is why - Move out of static van for the month of February (rules is rules!) and decamp to the house Well, I'll let you know how it all goes 🙂

Weeks 18 to 23 So it’s been a while since the last update, but a couple of weeks ago the scaffolding came down and we can finally see our lovey slated roof and the solar. I am very happy with the roofers who worked so hard in the cold and the wind, as we are quite exposed. Anybody in the South West looking for a roofer I would be happy to recommend them. On the inside I have started with the insulation between the rafters. I am using Rockwool flexi slabs 140mm thick with an air gap above. On the outside I have put some insect mesh up already before the soffits are closed up, it’s attached to the ends of the rafters and will eventually be attached to the battens/cladding. As per previous blog the costs of parting with the builder and finding our own roofer and solar has proved to be good. Their respective quotes have been invoiced for the same amounts as the quotes, no extras or surprise costs. A saving of at least £12,000 against staying with the builder as his quote would have also incurred extras no doubt as he didn’t include Soffits on his build quote or roof quote, and he acknowledged they had not been included in any quote. Carried forward total £140,645 Scaffolding for roof £1440 Roofing. Felt and batten. Slate with Brazillian Graphite natural slate 500 x 250mm. Hook fix system to costal zone spec as per plan. Dry ridge system Con6 with Marley modern smooth grey ridge tiles. Two vent slates. Total supply and fix. £16786 Supply and fix softwood treated facia and bargeboards. Eave ventilation. Complete counter batten. £2111 Solar 15 x500W solar panels and GSE in roof trays. (Interior fit to be completed once windows are fitted) Supply and fit £4357 DPM for windows £316 1 Pallet of Rockwool 46m2 (Expect to order 2 more pallets to finish between rafters then PIR under rafters) £580 First electrical order (cable and back boxes, enough to make a start) £280 Windows all paid for £20869 A few incidentals from B&Q and Wickes etc Brings the total to date of £186,757

Weeks 24 to 27 Windows Installation Choosing window style and supplier has been one of the hardest decisions. We finally decided on Aluclad wooden windows from Norrsken. It’s been a long journey and Norrsken have been with me on that journey since December 2022 to installation end of February 2025. A big thank you to Nick at the window company for sticking with me on my numerous window quotes, that took over 2 years to finalise. Due to my architect not thinking ahead how Part O would effect the design, the windows had quite a few changes and quotations from a few companies. In summary Part O (Overheating) was first published in December 2021, we didn’t submit plans until May 2022, we passed planning in October 2022. Then we realised that the original design wouldn’t pass Part O that’s when I started understanding that in my opinion the architect should have been planning ahead and designing with Part O in mind. We had an overhang in the design but not large enough to qualify as shading for Part O calculations. I spoke to a local company who could do the Dynamic modelling route to pass Part O but they had a backlog of customers who like me needed help to pass Part O some of which we’re probably going to end up spending thousands on solar glazing and various other mitigating factors. The company suggested I look at the simplified version first which basically is a spreadsheet on which you enter your room sizes, window sizes and orientation of the building. Although our windows were not too big the daytime overheating looked like it could be managed by tweaking window sizes a bit but nighttime bedroom overheating was more of a problem because we are a bungalow and the windows needed to open for ventilation but also be secure overnight against intruders whilst we slept, Part O offers some guidance and I found future homes https://www.futurehomes.org.uk/library#Guidancetoolsandtemplates particularly helpful. In the end we settled on replacing 4 windows with 6 large Velux windows that allow for more air flow and by changing some windows to tilt and turn inwards this allows the bedroom windows to be safely partially open in the tilt position whilst still being secure at night. We had to go back through planning for the window changes but the architect did the amendments free of charge and the revised plans were passed in May 2023. I’m happy with the end outcome. I still have lovely big picture windows allowing viewing far into the distance and without any glazing bars. The opening inwards will allow for easy cleaning, but cleaning is a long way off. The Velux windows free up room for kitchen wall units where we previously planed to have non opening windows. A Velux in the pantry as well as freeing up wall space for shelves lets more light in and probably will result in less switching a light on and off. The house is designed for us in that our en-suite is larger than the bathroom shared by the two guest bedrooms and by changing that window to a Velux it allows for a shower area that doesn’t have a window sill almost in it. I started researching windows quite early on because I wanted to make the most of the views but also I expected it to take a while actually getting round to see different companies. We moved to Cornwall to start a new business, have a field for our Greyhound to run in and be a bit warmer and sunnier than Manchester. I love living in Cornwall but it does have its downsides in that we live one and a half hours away from a motorway, our local home building shows are smaller than one hall of Birmingham NEC. We visited some of the local window suppliers but we mostly got to see one small window or a cut away demo window for each supplier and they didn’t offer a great deal in choice, mostly double glazed not triple glazed samples. If we went away for the weekend I would try to find a larger showroom we could stop at on the way, luckily for us Norrsken has one showroom in the UK near Bournemouth that we stopped at on the way to The Isle of White. We decided to get the window openings measured by the supplier, it cost approximately £800 for this but it was worth it. I had some questions about window opening sizes during the build before the concrete pour and Nick helped answering all my little questions, he knew how the window sizes had been changed to pass Part O. Even though the person sent out to measure ended up having a hour and half travel delay he still spent over 3 hours measuring and discussing the window location within the ICF opening and we marked on where I was to put the EPDM so it would be under the window and coming up the inside at the window board. The ICF is capable of load bearing the windows and fastening them back to the concrete core but the windows were going to be big and heavy (they come fully glazed) so we decided to use stokbord at the base of each window as our ICF was still soft enough that you could make an indent with just your finger (much like PIR) so when the weight of the window was resting on a shim it could push the shim into the ICF and general handling during installation could cause indents in the ICF. We used 3mm stocbord under the windows and 12mm under the sliding door. The 3 windows that look down the field were levelled and measured using a laser to ensure they would be the same height from the floor, and again a laser was used at installation. On installation day the fitters arrived at about 8am and the windows arrived shortly after, it was a great feeling that we were finally going to be watertight and to see our chosen windows. The installation team were all great you could tell they all had a role during the installation, Illbruck FM330 airtight foam was used and Silka EBT+ sealant. I am now taping the windows inside and out using Pro Clima tapes. We purchased 10 windows (4 non opening, 6 Tilt and Turn) and a sliding door. Windows P33A, 10 windows average uW.80 Sliding door S319A 2m wide uW 0.76 Aluminium clad, Marine Finish, Trip,e glazed.

I researched and purchased a plasterboard lifter that will reach 16ft and a table saw for the insulation under the rafters. The renderer is booked in for May, colours chosen. The wood cladding is ordered and ready for final payment so hopefully the next blog will cover the cladding.

Once again it's been much longer than it should have been since I last posted with my last entry being July, wow where has that time gone. Back then we were building the walls for phase 1 and installing the window and door lintels. Back then it was warm, unlike now and building could be done in shorts and T shirts Once these walls were built then it was time to think about a roof, even though it is going to be a temporary one for now as the whole house will have the final roof at the same time. This part of the conversion is designed to look like an extension as it did on the original. So, the South wall is higher and this 'hooks' on to it. We also have on-site building inspectors checking out their new home Then we had to start getting the rafters in situ, allowing for the overhang on the sides and end. The roof 'ladder' was built from the wood that was used to line the windows whilst building. These did take a long time as the roof is 4 degrees so slightly sloped so each block of both cavities times 2 had to be cut to the exact size required The weather wasn't always kind, but we did have some visitors to check out what was happening. Eventually, it was finished with the temp roof on. Windows covered for now as this will become our storage shed for a while During this time, we also had to move the stables. From this, already part demolished, not sure where the original pictures have gone. To this to this, luckily moved by a local farmer. Not sure when the horses will have them back though. Next is to start on the East side of the main part of the build. Originally our SE said that we had to have 2.4m deep underpinning foundations. But, our BCO had on on-side meeting with the SE as he felt this was over the top. We dug some example trenches to show what the soil was. He agreed with the help of the dog that it really is sand in this area. We do have some clay further on where we can have stepped foundations But he has agreed that we can have 750mm where it's sand so we are doing phase 2 which will be the office, master, bathrooms and 2 bedrooms. It will be the plant, another bedroom, family room and pantry which need deeper foundations. We have started digging out for the 2nd phase so will post my next update in due course. Thanks for looking and good luck with your builds

We have finally started to build. Day 1 was Monday 2nd September 2024. It was nearly 3 years from the first invoice which was for the private planning consultant to discuss and review the possibility of demolishing one of our old barns and building a bungalow on its footprint. Back then we weren’t overly confident of our chances but the consultant gave us a fairly good chance. Our current home is a listed property on 3 floors. It is far too big for us with 4 double beds, 3 baths/ensuite and two lounges. It makes a great multi generation home but no longer fits our needs. We are both in our fifties and looking to downsize into an economical to run bungalow. The old wooden barn was given away locally on condition they took it down and removed it without our help. We had birds nesting so we had a planning condition it had to come down between November and February. All that remained was the concrete down the middle, one wall and concrete lintels separating the bays. We chose a local building contractor from Bude, he came recommended and so far his groundwork’s subcontractors have been very good. The build starts with lovely weather but by the Thursday most of the UK has a yellow weather warning for rain, we had 23mm of rain Thursday, 14.2mm on Friday and another 27.7mm on Sunday. By the end of the first week we had a cleared and level site marked out ready to start on the trenches on week 2. Week one total man days of labour is 6

Back in ‘91 we self built the house we now live in. Block, render and pantiles. We were both working full time in those days and we did as much as we could, but that doesn’t include groundwork, blockwork, structural carpentry or plastering. Rural location, fields front and back, nice big garden. A third of a century later, at the end of September ‘23, we found ourselves in the back garden of a small, run down 1920s or 1930s timber framed bungalow. It’s in easy walking distance of the centre of a small market town, even closer is a lovely riverside walk, on a quiet-ish road, near a park, and the long, narrow, over run back garden in a quiet little oasis made of half a dozen other long back gardens. For us it’s the location to die for. Especially with our first floor bedroom overlooking the back garden. But the dark and sad and unmortgageable bungalow is not to our taste and crucially, it doesn’t have a first floor. Yet. On one side is another bungalow (a matching pair to ours) but fortunately on the other side is a two storey house (phew!). So we bought it, and put in a pre app during the buying process. The feedback came in (with some gentle, respectful encouragement) just before exchange and that feedback was generally very positive. Between exchange and completion we worked out what we wanted to live in and we met a couple of architects on site, one of which we were happy to work with so we engaged them. As soon as we completed in mid January we submitted our planning app, and we felled some trees and cleared lots of shrubs so we could start to see the garden. I quickly got to know the guys at the tip and I got much better at reversing Trevor the trailer. Our planning design is v close to the pre app design save changes hinted at by the planners, and in early May it was permitted without modification. Woo hoo. A few conditions (e.g. can’t start till September) but nothing too onerous. So, that means lots of time to research, plan, analyse and generally overthink just about everything! Now all we need to do is sell our house….

Over the last couple of months we have made steady progress. But, I've been very remiss in taking photos. Last time I posted we were busy building up the walls in phase 1. It's now ready for the lintels, which we waiting a month to be delivered. This one requires some blockwork changes as the overhang is over a block joint. This is the inside looking North looking down over the valley. This is the outside looking in, again some block changes needed. We used thermally broken IG lintels, which were on a 4 week lead time so to fill some of the time we have been prepping for phase 2. We realised we didn't have enough space for concrete lorries and storing the spoil so we moved the soil spoil heap further into the field. This doesn't look much, but it took 3 days and countless repeats of load dumper, move and tip, and repeat !!!! We've also moved into one of the horses winter fields, but we will return to a field when we've finished. Apart from putting block on block and repeat we've bought a few items at auction. We got some windows that are exactly the same model as we are ordering, maybe not the exact size, but we can make them fit. Of course the cill will be replaced. We also got a lovely sink for the utility room. For the first time in months we are dry on site, not sure how long it will last. At the moment I'm trying to order the posi-rafters for phase 1, but I need some input on a beam from the SE who is being very un-responsive. We've realised that we have a beam on our SE drawings which say 'B3' and no details. He initially responded saying it could be either an RSJ or a flitch beam, but that was 2 weeks ago. I was told last week that the rafters are also on 4 weeks lead time. Once we have those then we will be putting some of the barn roofing on as a temporary measure as we'll get the whole build roofed at the same time. I'm horrified at how little we seem to have done, but as I'm no longer working at home I think the work force (hubby) may be slacking 🙂 More soon, when I have some proper progress to show. Jill

Yesterday we exchanged contracts on the purchase of a house in Lymington and on the same day we submitted a planning application to demolish the house and build a new house in its place. Probably Timber Frame, definitely to Passiv Haus standards (fabric first etc), 225 m^2, no fossil fuels but plenty of solar complemented by batteries. We have done this before with a TF house in 2009, a small development of brick and block houses in 2015/16, and an ICF house built into a hill in 2017. We hope for a simple, fast build with a high quality result. One thing we have learnt is to always be ahead of events and don't change your mind. Let's see

Despite the yellow weather warning we luckily had the coastal wind pushing it away, most of it fell on Tuesday but only 6mm The trench foundations are excavated and inspected. Then the concrete poured, and the first blocks laid followed by dolly blocks and internal supporting wall starter blocks Total man days of labour for week 2 is 13

So I spent 3 days with a 1.5 tonne excavator and a pecker breaking up the huge amount of concrete slab. Thankfully, it wasn't reinforced and all I can say is that I didn't envy the neighbours. I am just finishing off pulling up the broken slab with a 3 tonne machine and getting the concrete collected with a grab lorry. There is about 5-6 loads to collect and that is going to cost me about £700. I could have hired a concrete crusher, but I calculated that to hire a crusher, 5 tonne excavator would have exceeded this cost. I also do not have any water on site for the dust suppression, and there was a lot of large lumps, that would have not fitted into the crusher without having to broken up smaller.

The roof rafters are being installed with the openings for the roof windows. LABC visits for the second time, there have been a few photos sent as well, they inspect the roof, anchors and fastenings etc. The internal walls are built up around the steel goal posts. Not as many hours on site this week were one man down, its half term here. I started a Gabion wall, filling it with rubbish stone and facing the front with nice stone from around the plot, it just separates off the garden from the vehicle parking area, holding back about 400mm depth of soil. You can see on the photo the remaining post of the old wooden fence which was behind a skip now removed. Total man days of labour for week 8 is 20 days.

On Monday the internal structural walls are up to the top of the ICF walls and are tied in to the ICF walls. The windows and doorways have extra bracing ready for the pour. Nobody on site on Tuesday it rains all day and no more prep is needed before the pour. Wednesday starts with the last minute checks ready for the pour. The concrete pump arrives on site at 12pm it takes 30 minutes to set up before the first concrete pours out. We have 4 builders onsite plus the concrete pump operator. The concrete is poured into the ICF on all four walls in stages twice round and its up-to window cill height, the ICF cills are pushed into the wet concrete and the wood boards replaced so that the pour can continue higher. A poker is used to vibrate the concrete to ensure the concrete fills the ICF without any voids. At 4pm the pour is finished and the cleanup can start. The pump driver tests out our hammer head turn which was required by BC as we are so far from the road and Fire Engines are not allowed to reverse more than 20m. I think this proves our access works and it’s all down to the driver of the vehicles, the pump driver is great if only all delivery drivers are like this. The gables will be completed later so the concrete has rebar inserted, the other two walls are trowelled level. By the end of the week one gable is braced and poured. Total man days of labour week 6 is 17 days.

Another beautiful week in Cornwall only 7mm of rain on the Sunday The week starts with laying the soil pipes then it was sand, hardcore, burying the soil pipes, laying the radon barrier, mesh and more concrete for the slab leaving a lovely surface to start the ICF walls next week. And the field was cut and baled, not as much as a normal September cut due to us moving our spoil down to the far field and tramping the grass down and making a very very muddy gateway between our two fields. Nether the less it was 10 bales for our friendly farmer Rob. Total man days of labour week 3 is 9 man days Cost to date Brought forward from blog Building Regs, Part O and SAP £14625 Refund from Architect £300 Fee to LABC for inspections £600 Foundations Weeks 1 to 3 £30,000 Total to date £44925

With any self build, unless you can afford an Architect/Builder to oversee the whole project, you're going to be chasing people, materials, answering questions and more. My own project is up to roof stage, timber frame is finished, roof finished but outer brick/block leaf is next, then soffit, fascia, gutters, then porch, then windows & doors. Each have their own challenges. On top of my day job! I've a delivery of lintels tomorrow and I only thought to ask what size rigid truck is it to find out it's a full Articulated Truck with a moffet (look that up in goggle!!). Won't fit in my housing estate!! cue plan B, C and D !! We're going to offload it to a footpath outside my house on the other side of a council wall and I'll use a hand truck to get them one by one into the site through a gap some teen made wider last year and it was never fixed by the council! I'm sure each self builder has a raft of such stories. My house needs 2500 bricks and 1280 blocks. The brick supplier I'd booked and paid for in full, was meant to deliver this Friday along with the block supplier providing all the blocks, sand, cement etc. They gave away the bricks to another (assume larger) customer and it's 2 weeks to get a new order in from Belgium. I tried the other supplier I found in google for the same bricks and got through to the same woman I'd been dealing with, same company, one's a shell I'd say. Tried the supplier and they only supply to this one company in Ireland. Anyway, as a one off house they can bump you down the list so I tend to like to get things onsite a week or two early to avoid this added hassle. I've very tight for storage but if you have a brick layer onsite and no bricks you'll be forced to buy something, anything and have to live with it forever. Time management - getting answers to questions is one thing, learning on the job is another. I want to nail in about 200 nails by hand but after realizing my initial attempts were leaning tower of Pisa'esque, I purchased a first fix nail gun, my first! Wow! 200 nails in 3 hours, all batons attached to the window openings. I can sell it later but the right tool for the job for sure! I've to install my first express nails tonight after learning about them from a neighbour - fixes wood to concrete. The roofers left 6 Velux boxes behind with BBX on them. What are they for? An extra? Do I need them? I think they are to act as a vapour barrier and possibly air tightness according to initial google searches. Something else I've to figure out later on. The roof has turned out well hasn't it! They had to finished the Oriel Window Metal / Trocal flashing before they finished roof tiling. It has a ventilated ridge and those plastic covers at the edges all the way along the roof line instead of cement they used to use. I've about 40 spare tiles stored away! The outer brick/blockwork is my next major hurdle. There's a few items I need to buy, figure out and get onsite: 100mm DPC for above 1st course of blockwork above foundation 18" DPC for around windows Expansion ties - Ancon PPS200 ebonded Safety Tie - box of 250, at least I have spares! I can return the unused ones. Wall vents - using Timloc Cavity Wall Drill Vents - you drill a 25mm hold angling upwards and then plug this into it. This absolves the brick layer from having to install them as they go Wall ties - the timberframe supplier provides 4 boxes of these and marked up where the studs are to get good purchase Stop Bead and Drip Bead (plastic) for render, Weber OCR, Weber paint (I'm doing this job once the blockwork is finished), Mitre bond glue (2 part glue) Gutter Brushes for later Expansion Joints - I've two 10 meter gables, each require two expansion joints. There's an awkward window and ESB box on one end of one side so thankfully we're putting the expansion joint past both of these even though you should have one every 6 meters and within 1/2 of this distance from the corner, ours will be 3.8m from the corner. the timberframe amazing team marked up the best positions for expansion joints and identified this one before the Structural Engineer signed off on it. I've taped up all the Solitex on the outside of the Timber Frame, plugged the side door up with timber, OSB and more Frontex WA. We're still installing a lintel in the blockwork but will ignore it otherwise for the block course and if someone wants to open it later they can with an angle grinder! It saves wasting a lot of space in the utility room having a door there with no purpose. There's no sink = reason to not make it a boot room really. I'm lining all the window openings with insulation over the next week or so and adding batons to take the window straps. They want a strap within 100-150mm of any corner and no more than 700mm apart. The Straps are 1mm thick and come inside the window about 100mm. I've sourced wood to exactly match the insulation thickness which can be hard but avoids trying to plane / table saw wood onsite. This Friday I've to hope everything fits onsite as it's delivered and we've room for a telehandler afterwards for when the brickie's start! That's a snapshot of my week! I'll do a post about powering electrical devices onsite without a generator using an Electric car & Anker 2kW battery soon I think, some lesson learnt there!

After my horrid time earlier this year I am now going to post something more positive. As of yesterday, I was offered a job, not ideal (is any job ideal), rather than working from home I must go to the office which takes 40mins each way and hubby is disappointed that he will be left on his own all day. That said even with time out for funeral 250 miles away and wet, wet, wet we have progressed. Some pictures. hardcore & binding (take 2 after previous issues) now the expansion foam around the sides The heave protection next then taping next was the rebar here is the pour on top of the rebar - 200mm drying concrete slab with no hint of everything underneath, typical building, lots of expense and nothing to see. the first row of outside blocks added showing the cavity first blocks over DPC with all the rain we have created a bit of a swimming pool It was at this point that we purchased a puddle pump as hubby really didn't like having to kneel and build low in water going up with some windows & doors framed insulation going in joining the existing walls to the new part this is where some of the kitchen cabinets will be hung, so although internal we are using heavier blocks to take any necessary weight On the left hand side you can see part of the existing barn that will be staying. The roof is currently being held up with barrels and wood building from scaffolding is a real milestone, makes it seem like we are getting somewhere. To protect the insulation, we have the original insulation from the barn roof cut up to provide a 'roof' over the cavity. Having made the frames for the remaining to windows these need to be placed in situ for building around. This area will be our front hall and snug. Of course, the front door will only be used by visitors, but we will go through the hall internally to get into the snug. With all the cavities it is smaller than I hoped, but with all the insulation it will be much warmer than our single skin house. Hope you enjoy the pictures, next time I hope to be at lintel and wall plate level, but we would like the weather to improve. Thanks for reading Jill

The week starts with the removal of the external walls on the rear half of da bungalow. That’s the fun bit. I’m armed with two chainsaws and a reciprocating saw (aka sabre saw, for some reason). I bought the sabre saw as Steve the builder recommended one for demolition. When I bought it I knew it would be useful, but I knew my trusty chainsaws would get more done quicker and easier. It’s not easy working with someone who’s right every damn time. Sigh. So the chainsaws remain at rest while we quickly get into a rhythm of joist then upright removal, working our way along the frame till the only part of the rear half standing is the chimney and it’s wings (and our neighbours wall are still untouched ….yay!!). The pile of wood at the front of the plot is now clearly tidal. We cut wood, the tide flows. The ‘wood man’ comes, the tide ebbs. The cycle disguises the sheer volume of wood we are handling. It constitutes an awful lot of skip savings. Next day it’s straight back to heavy spade work for me, knocking of plaster and trying to leave the metal lathe mesh stuff reasonably clean to make later processing for recycling easier. In the process I discover previously a hidden window and a door - it would be fascinating to understand the history, the sequence of events and the reasons, but we can only guess. Steve is straight into heavy hammer work taking down the chimney and wing walls, and he discovers thermalite block so that chimney isn’t original either. Most interesting. Nobody tells you about the dust when you talk about demolition. I thought I’d done dusty jobs before but not like this. It’s like you bath in it. Everything on site is coated and one touch leaves my hands feeling almost ‘smooth’ in a strange kind of way. The dust masks that started off annoying are now comforting, I now start the day clean shaven to help them work better. But they discourage hydration as lifting the mask up to drink means putting a sweat soaked mask back on one’s face. Less than ideal. Warm dry weather makes it worse, and when a stiff breeze gets up it really is the limit. My goggles fully protect my eyes from dust. Unfortunately they also protect my eyes from seeing anything, as they mist up in seconds each time they are cleaned. I sprayed them with de-icer and that did help - it trebled the time it took them to mist up - sadly that still only made about two minutes. So, back to specs type protection it is. The high velocity flying bits are deflected but the fine dust floats round and gently crusts, aided by the breeze which isn’t enough to cool me but is easily enough to ensure dust gets everywhere quickly. Skooby (trusty steed, or cheap ancient Skoda on her last legs bought for the build, depending on one’s point of view) now has a light gray interior. Not just from my clothes, though that would be enough, but also from the stuff piled in her for the tip runs. And the litres of moisturiser I get through is crazy - we never budgeted for that - the dust dries the skin like mad. But, one just carries on. So having removed the back half the question is what to do next. Steve is logical and methodical. So he advocates carrying on removing the rearmost and working our way forwards. That means the dunny. But I still have a bladder, and age dictates that that bladder is attended to regularly. And I’m tight and we’ve nowhere sensibly to put a rented thunderbox anyway. So the score on that one ends up as Common sense: 0; G’s bladder: 1. So, after adding some diagonal bracing ‘just in case’ we bypass the loo and work forward. Yet another carefully considered risk assessment debate ensues. These consist of Steve standing and looking for a bit while I remain silent. He then says what we are doing next and I say yes Steve. Simples. In this instance we are going to remove the lintel above the old front door as otherwise when we remove the studwork near it there might be instability, as one end rests on a tiny masonry pillar held up only by studs. It takes an hour to drop the blockwork above and the large catnic lintel we discover. More to clean up and sell, if only I could lift it. Then, finally, it’s back to studwork removal time. The ‘wood man’ has been again so the wood tide is thankful out, so there’s space to put the wood mountain. Another excellent four days, so much so that we all take the Friday off. It turns out that being at home on a day off is emotionally, much easier than visiting site. A few jobs need doing around the house which helps, but it’s basically ok. It tells me that I could never live on site and have any peace of mind. I already spend a lot of time thinking things through/worrying myself into a fizz when I should be sleeping, and I think that would be massively greater if we lived either in site or very close nearby. The 20 minutes in Skooby as she grumbles along is vital to prepare for the day and then later, to help me start to decompress. It’s easy to think about one’s muscles needing rest, but not so easy to think about one’s head, but I’m trying, and it seems that that drive, and a soak in a scummy bath, is as vital as talking the day over with J. It’s like mentally putting one’s tools away, clean and tidy. Cooking helps too… Saturday it’s time to get all the lead, the house wiring, and (as it turns out) 80kg of gas boiler to the scrap yard - no wonder the boiler was so hard to lift!

I've two last major areas to details for air tightness and insulation - this post relates to one of these - a single rear Oriel Window, an architectural feature that juts out from the rear of the building and is finished externally with a metal standing seam. The plan agreed was to create a 20mm lip of metal for the window to sit against. I was right about to commence work when I noticed dampness and beads of moisture and sure enough despite the window being surrounded by a later of insulation, because I didn't think through this detail on the inside, the 2mm metal is bringing in the cold outside and condensing - even though the inside is only 5-7 degrees or so! It's happening all 360 degrees around the window and dripping down to the bottom of the frame too. Obvious in retrospect why this is the case now and lucky I'm aware now due to the time of year so I can address it. I have other metal in the form of an I beam supporting the side of the porch cantilevered outside (80% inside, 20% outside) but this is dealt with by the timber frame company using a thermal farrat - the beam is in two parts and bolted together through the farrat reducing cold bridging immensely. I'm keeping a close eye on this internally during this cold spell to satisfy myself. Anyway, if anyone is to blame for the detailing it's me, it just happened and I had considered angle grinding off the lip to get a better seal as the 2mm metal meanders a bit making it hard to pin against the window frame with rigid insulation or squeeze sealant / spray foam either side of the metal continuously. The window company didn't recommend the angle grinder as the lip provides a water barrier if the external sealant fails. The company I buy my gutex and air tightness products from were confident that covering the metal lip with insulation and using tape would prevent air circulation and address the issue. So, onto the fix: I'm working with Gutex for some areas of the build, a wood fibre board. Messy when cutting (accumulates inside my circular saw) but easy to work with. Not cheap but I'm trying to stick with breathable, natural products and gain experience in their use. I've used Multitherm which is a T&G product around the windows, this time I wanted to use Thermoroom which is a non flexible flat product (no T&G) that I could stack up around this opening. I plan to finish off with a fire rated (A/B) oak veneer rather than plasterboard so needed batons to attach to (main use for this ply is around the internal picture window separating the kitchen from the bedrooms, hence the fire rating but it will match nicely if use in this other area too. I'm going for an air tightness test soon so my current finish is intello plus only so I can inspect and pinpoint leaks. I packed out the Moy Metac flexible insulation and then cut a few Thermoroom boards to size. The board is a lot smaller than the Multitherm so I cut them in half minus 20mm to get the width I wanted and they stack at 50cm heights on top of each other. Battons to secure although I'm finding it hard to get 150mm screws through the baton at times and then through the gutex to bite into the wood frame beneath. When I could get my weight behind it it helped but overhead was a nightmare. Ended up drilling 5mm holes as the top 50mm of the screw was unthreaded and I just wanted it to bite the wood 120mm away and clamp the baton, this worked fine but I've 180mm structural screws to use under the vaulted ceiling later! Drill was set to 15 but still rapped out a lot of time, any suggestions?! SDS with a clutch?! Needed to get a lot of speed up and push force to work. Once the batons were on I filled out the spaces with 50mm rockwool and stapled on the intello plus and tescon vana joined them. The lighter blue tape is tescon profil which has a separated backing allowing you to seal onto the intello first and hinge the tape 90 degrees before removing the 2nd backing to seal to the window. So all 4 sides are now done. I've 11mm OSB on the floor of the opening rather than batons, this sits on 60mm multitherm on top of 25mm bosig phonotherm, a structural insulation board I had spare offcuts for. As this will be sat/stood on a lot I wanted something more secure to sit the plywood on. Now, it's just a case of monitoring and checking if any evidence of condensation still occurs, maybe peeling back the tape in one or two areas and quickly checking but I'm happy for now! Lots more to do. I've to figure out the 6 x Velux openings next and box out about 400mm of splayed / insulated / air tight spaces and close off the last part of the roof. More tower work for me so!!

The builders scaffolding came down and the roofers scaffolding went up all to plan. The new roofer has a good gang and they are working well on the roof. The weather hasn’t been great, we have had three storms Bert, Conall and Darragh luckily no damage to the build. We are approx 615ft above sea level and about 2.5miles to the coast as the crow flies so we get a good breeze coming in off the Atlantic. The wind has Brought with it some very cold spells that and the shorter daylight hours has meant progress has been a bit slow. The roof has been battened, breather membrane and counter battened, eves ventilation and we have some nice joinery on the gables, facia, tilt fillet at the eves for the last slate row and overhang. The slates are looking good and I’m happy with the hooks they are using, sometimes they are quite visible when the sun catches them but these have black tips that blend in nicely. The overhang also has some nice leadwork. The solar panels have just arrived and work will continue next year with the installation. The MVHR vents are installed and the Velux windows are installed, one window still needs its flashing kit completed and slate around so is covered up for now. Whilst the scaffolding is up I have managed to give the bargeboards 3 coats of wood protection with black stain. Finding time when its not too cold for the stain which requires 5 deg plus and keeping out of the roofers way has meant a little at a time but the gables are done and the facia on the North side is done with just the South to have another 2 coats. Im glad I’m doing it now not just because the scaffolding is up but also any drips of the very watery stain are not going on my cladding. We are ICF as you know and we have to be careful that the preservative is solvent free or it would melt the ICF blocks. Whilst the scaffolding is up we have also put the counter battens and insect mesh on the gable ends ready for the cladding next year. We purchased the insect mesh quite wide to go from the battens to the inside of bargeboards. Next job whilst the scaffolding is up is run some sealant in the small gap between the slates and the gable ladder, I have been told this is not done on most sites these days but due to our location the roofers have suggested we do it, so I purchased a huge box of baby wipes ready, I’m sure I will use them when we seal the windows as well. I have moved two empty slate crates just off to the left of the camera and started filling these with the half cut slates and the broken slates. The plan is to may be use the half slates around the bottom of the walls above ground level before the cladding starts, I’m hoping sticking them on will be the easy option, the broken ones will be crushed more and used as mulch on the ground around the edge of the building. We have paid the window deposit and the window openings have been measured, for one sliding door and 10 windows it took apx 3 1/2 hrs to measure the openings and discuss the window placement position and the sill positions and depths, and the sliding door placement taking into account the ffl after the insulation, screed and wood flooring. Some walls are being rendered and some wooden clad so the sills are different depths. We have 3 windows on one wall that face down our field and I wanted them levelled with a laser as well as measuring as these will be a big feature. We paid apx £700 for the measuring service and it will have been worth every penny. The windows are due in production towards the middle to end of February so hopefully before the end of March they will be installed. The cars that managed to sneak onto the photos for this catch up include our own Jensen FF back from the painters and a local customer popped their Jensen 541 in for a quick service.

At the beginning of Week 5 the scaffold arrives. The ICF walls get past window header height so they can be boxed in first with the ICF to close the side jamb, header and cill then the wood brace for the concrete pour. The internal structural walls are started and tied into the ICF. These are to support the steel roof beams. Its good to stand in the open plan kitchen and lounge area now and get the scale of the room, the three windows look down our field to the East and the slider door opening looks out South towards Dartmoor, visible on clear days. The kitchen may look a bit dark but it will have 4 velux windows that as well as providing light help to zone off the open plan area. The photo from the scaffold shows our workshop in the big barn and beyond that just visible is our current home. The weather has not been too bad during working hours, a mixture of sun shine, rain and strong wind with gusts of over 43mph so I will be happy to see the pour next week. This week the car is our own Jensen Interceptor my husband took it out in the sunshine when he went to our local ‘Men’s Shed’ in Holsworthy. Total man days of labour week 5 is 23 man days.

How things can change on a six pence! After deciding to go for the ASHP, I had a couple of local firms in to quote. CVC did come back with a quote of around 20K but without a site visit, I was worried things could add up and that seemed too much. see the whole ASHP saga here; So next week, the new ASHP is being installed. And the unit is going in the back garden, under the kitchen window. This is not where I wanted it to go but the company were adamant that we could not have it at the front of the bungalow. And with certain changes in the pipeline, I am not sure now that we will be doing the extension at all. therefore I am going with the easy option for now. If at a later date, we DO decide to add an extension, we'll just have to move everything. 🤔 The reason for the big change is that the property next to this one came up for sale and after looking at it, we decided to put in an offer. It is larger than our current bungalow and while my parents need help and care, it makes sense to be next door, rather than a 20 mn drive away. It ticks all the boxes for our current situation, garage, workshops, as well as being next door so seemed the right thing to do. We now have a complete chain so are just waiting for it all to happen - hopefully January 2025. Fingers crossed! Looking to the future, we will have the option to choose which we live in and which we sell. OH prefers the new one already....... and we arent even in yet. 😁 I'll update things once the ASHP is in. I just hope it works as well as they say it will.

On Monday the second gable is poured and most of the internal bracing, corner bracing and window shuttering is removed. Tuesday rains all day so no work on site. The internal floor is under 1 inch of water with no way to escape, without us brushing it towards soil pipe. Good to know we are airtight at the floor/wall joint. The steels are installed, we were supposed to have wooden roof beams but somehow this was not calculated by the architect who insisted the roof truss company would do the calculations later. The roof truss companys only want to do the calculations when they know you are ready to order and they said the beam spans could not be done. So on the last minute we had to go back to the SE who worked out our steel beams and the total cost of roof went up £8k. I wish the architect had suggested the SE looks at the roof calculations earlier but unfortunately we just have to move on from this, and up to this point we have had no other extra costs. Since we are no longer working with the architect I have had to find a new SAP assessor who I can engage with as the build progresses. We have been discussing how changing the steel beam might change things as the vaulted ceiling can now be higher if we want. This gives us more space to heat up. I also wanted to know the effect of not putting as much solar on the roof or not having the wood burner changes the SAP results. Since having a smart meter fitted at home we have reviewed our current electric usage and decided that less solar (7.5 kwp instead of 11 kwp) but with the ability to add a battery. Also I think aesthetically one row of 15 panels will look better. Total Man days of labour week 7 is 16 days. Total to date b/f £44925 New Design Stage SAP Calculations (previously done by architect) with ongoing advice about changes that will affect the SAP and to include the As Built SAP documents and EPC at completion £720. It does seem a lot compared to online prices but for peace of mind knowing that we can if we choose to only put 6kwp of PV on the roof instead of 11kwp, is an overall saving. Total to date £45645

Greetings on a miserably rainy Sunday October morning. Perfect weather for catching up on some blog writing! As the title suggests this blog will be about our external coverings of the house and, by the end of it, the outside of the building will be pretty much finished allowing us to crack on internally. We started many months ago by battening the outside of the buildings. As we are having external blinds and they have a requirement for fitting the blind cassette we needed a large gap between the house walls and the outside of the cladding. This meant 50mm x 50mm timber battens and counter battens. We did this ourselves and saved many thousands and, even though it was slow going (as, it seems, everything is when you do it yourself!), it was very satisfying with the carpenter saying that it was good work and he’d seen chippies do a lot worse jobs than we did. Nice warm fuzzy feeling ensued. We are having a mixture of burnt Siberian larch (https://en.wikipedia.org/wiki/Yakisugi) and, to contrast the black, standard Siberian larch on the ‘arms’ of our property and entrance porch (all will be revealed in photos below) and I ordered all the cladding to be delivered on-site prior to the carpenter starting. The carpenter started on the garage using the standard Siberian larch which we bought from Jewson at a very reasonable price, and quite a bit cheaper than we could get from the usual timber cladding suppliers and we are very happy with the quality of the wood. He then went on to the black charred larch (which gets everywhere and he and his tools looked like they’d been in a coal mine by the end of each day!). We purchased the charred larch from Permachar (https://permachar.co.uk) who gave us a brilliant price. The wood itself was burnt and delivered from Lithuania (https://degmeda.eu) but they will only sell to the UK via Permachar. It is stunning wood, but incredibly fragile and any sort of dragging or scraping will cause the black char to flake off. While he was busy doing that and while the scaffolding was up I thought it a good time to get the guttering started. Our architect specified Zinc guttering and after a lot of thought and looking at stainless steel and zinc we also decided that zinc was the choice for us. We ordered it from Rainclear (https://www.rainclear.co.uk/guttering/copper-zinc-guttering/guttering-fittings.html?color=235) who offer next day delivery if in stock and were incredibly helpful and very well priced. It’s also a clip on system which even I managed to install without any major issues! Around the same time and while the carpenter was busy putting the cladding up our external blinds got fitted. We bought those from a local company called Powell blinds (https://powellblinds.com) who stepped in brilliantly at the last minute after we were seriously let down by Cornerstar Aluminium (long story which I won’t get in to here). The blinds are fitted up behind the cladding above the windows but externally so they will be hidden from view when lifted up. We absolutely love them and during the heatwave this summer we lowered them and this drastically reduced the temperature inside the house. There was still one large south facing window that didn’t have blinds that needed shading. We wanted and the architect designed a Brise Soleil in this area but all we had to go on was a 2D drawing. I contacted a few companies about getting one made and installed and the quotes came back at between £6k - £7k! A figure we simply could not afford. So I did research and spoke to a local forge called Horsham Forge (https://www.horshamforge.co.uk) with an idea I had. He said ‘that could be done but how about this instead?’. He suggested brackets with a pole running through them and vertical timbers slid on. Genius! On to Sketchup where I draw up the brackets and gave them to the forge to be created and spoke to my timber manager at Jewson who procured me some thermowood at the size I needed and got my carpenter to fit it and it cost me £1700 in total. So we saved around £5k by doing it ourselves and we also enjoyed the journey and got a solution that we designed (with the help of the forge of course). We think it looks fab and it does a good job of shading from the sun apart from a couple of hours when the sun is directly facing that side of the house. So we will still get some solar gain but it is definitely reduced and it’s a brilliant architectural feature. 😉 Right, while all this was going on the chippie was finishing up the cladding and now that it is all finished and I have put the downpipes on we have an almost finished external facade to our dream home. We love it and think it’s stunning. So very happy with the carpenter’s work (http://www.kmlcarpentryandroofing.co.uk). Kieran’s attention to detail at the junctions between the 2 types of wood is fabulous as it is in other areas too. He would also discuss any issues and potential solutions with us to make sure we were happy with them rather than just doing something he thought was right. Hopefully the pictures below do it all justice! (Note: please ignore the 110mm brown downpipe in the below photo! It will eventually be a rain chain but this works for now. 😉 ) Thanks for reading and we hope you like what we’ve achieved so far.

We have managed to stay in our home for the majority of previous builds. This time we had to sell before we could buy the plot / donor house. So yesterday, we packed up from our 325 sqm house in Stroud, moved into a 114 sqm rental house, sold Stroud, purchased the plot and by coincidence the Planning Application was accepted by the District Council. A big day. https://planning.newforest.gov.uk/online-applications/applicationDetails.do?activeTab=summary&keyVal=_NEWFO_DCAPR_221599 We have a mountain to climb, but already we can look back on some good progress. We have a plot, we have a design, we have planning submitted and we are some weeks into requesting Timber Frame quotes. Many priorities, but one near the top of the list is talking to the neighbours to see if they will comment positively on the planning application. As a courtesy I gave the drawings to the immediate neighbours before planning submission. Good neighbours are invaluable, especially for demolition and a replacement dwelling.

I hadn't realised that my last entry was in Nov last year. Where has the time gone. As with many self builds, particularly those on a DIY basis we have been very subject to weather slowing things down, not that it could be much slower. But, in fact compared with last year we have done loads. The NOT wall (the side of the barn that was open) is now a wall. This wall is 16m long, with 4 lots of French door gaps. double skin block with 150 cavity and 4 heavy lintels. It then turns the corner to head south. We also had a big overgrown bank which we dug out and cleared. Then out next door farmer came and took away all our soil spoil which we didn't need for some holes in his field. About 40 ton we think. And in the process flattened the bank. I then planted a hedge and seeded the bank. Inside what was the barn we have started digging down, in total it needs to go down 500mm so this is just a start The back bank needed digging back to allow for the digger for drains when we get to that stage. And finally in March we've started taking some of the remaining roof off, to be the stables roof in due course Hard to believe this has gone from bog to beach in a couple of months. Once the roof is dismantled then we can start with the trenches for phase 2 of the build. Thanks for reading. See you next time,.

The last bit of soil pipe and inspection chambers that are close to the house are completed. The ICF is delivered and by the end of the week we have the start of door and window openings. The insulation is extruded polystyrene XPS 100mm each side of the concrete cavity. U value of 0.14 The windows have rebar in them before 50mm insulation closures are added. At the weekend we had a yellow wind warning for the South West, our home weather station recorded top gusts of 40mph. I’m pleased to say the R-wall ICF survived with no problems. Total man days of labour week 4 is 22 man days split between Groundworks and ICF builders. The build is going on very close to our workshop entrance which makes the delivery of vehicles and test drives limited. This week we took delivery of a previous customers Jensen CV-8 which now has a new owner who has sent it to us for further works over winter.

Thanks to the relatively mild weather this winter i decided to start chipping away at the bathroom project, which is being extended into part of the extension which was finished over a year ago. This gave me the opportunity to install the bath, sink and toilet in the new bit, at which time I’d totally disconnected the old bathroom allowing me to strip it out and that’s worked really well for my as I struggle to do more than 4hours in a single day so I could keep doing a bit and stopping when I’d had enough. didn’t fancy tackling the ceiling for plastering in the new bit so got a pro in to do this bit for me, all done in a couple of hours which was nice. and made the most of the space and got the painting done after putting a layer of 10mm marmox board down ready to accept the underfloor heating mat Next job was to start making a frame to hold the toilet frame and the sink and cabinet Decided on making my own cabinet rather than paying silly money for an MFC one, got pine furniture boards, a pocket hole jig and a new router and came out with this which I’m pretty happy with that all got painted and the sink installed, wall mounted tap and the wet room panels that I’m using both for this and for the walk in shower area all installed. got to work cutting the OSB backing and wet room panel for the toilet in prep for the final big push to disconnect the old and commission the new, that was a hard days work! And then bath and toilet all installed once the shower area is complete the bath will be disconnected again to lay the underfloor heating, self leveller and the flooring before being put back in place, and eventually building the wall and plastering it. Made a start on stripping the old bathroom out Next job is to patch up the loft insulation where the old spotlights were, new wiring in place for a single light fitting this time, airtight membrane adhered to the walls and then battens before reboarding it ready for plastering. Floor is coming up also to be replaced with 22mm chipboard to match new bit.

Week 13. Or at least, my body thinks it’s week 13, whereas the calendar says it’s week 3. It’s really odd looking back on the demolition. Starting to strip tiles off seems so much longer ago than 20 days. Most odd. The week started with a tidy up day, as Steve wasn’t there. Almost all of the wiring for da bungalow ran through the loft, and was set to be in the way so out came my new and wonderfully sharp side cutters. About 5 minutes in they went back in my pocket and were replaced by a cordless angle grinder with a thin metal cutting blade. Super quick especially when a bunch of wires were involved. Habits and techniques quickly and unconsciously form through trial and error or, more often on this project, by watching Steve. He’s had best part of five decades building and I’m lucky to be able to tap into that. More luck comes in the form of a guy scrounging firewood at the tip. Phone numbers exchanged (goodness that sounds dodgy!) and a promise to let him know what we have available. It transpired that the ground worker didn’t have a use for our roof timbers so in two runs the wood man has removed about 5 cubic yards and wants all but the nailiest bits. More skip savings and he seems to understand that for it to work he has to turn up when agreed and load up without help. Marvellous. So on Tuesday we started stripping off the internal plaster. The external walls are 4” x 2” stud with metal lathe either side then pebble dash outside and a weak cement render inside with a skim. Between the studs is a patchy application of white fluffy insulation, which had settled significantly, or was completely absent where they missed sections. A fantastic illustration of the cowboy insulators of yesteryear. The plan was to knock off the internal plaster, then peel off the wire to grab and bag the fluff section by section, then thump the pebble dash off from inside. We had visions of the whole neighbourhood being covered in wind blown non bio degradable fluff for decades to come. We soon discovered that the tool of choice was yet again, my trusty spade, backed up by my SDS with a funny crushing bit. Hours of hacking leaves the wire mesh clean enough to go in metal recycling. The render was then barrowed to the growing aggregate pile in the back garden to be used to build up the solid floor. Peeling off the metal lathe involved much yanking with a nailbar and we generated an enormous pile of plastic bags of captured fluff, the only non recyclable bit. Quite pleasing. The frightening bit was knocking off the pebble dash. Too easy. It came off in huge bits with very little effort. It happened so quickly that once we’d cleared that up we had time to start cutting down some stud work. We started with the end wall. A couple of high level cuts and a gentle push and down it fell into the garden, in two sections, with a small plume of wood dust from the disintegrating rotten sole plate. If our neighbours see these bits they’ll be scared stiff at the likely condition of their near identical bungalow, built as a pair roughly a hundred years ago. The chimney and masonry wall in the centre of the bungalow forms a stable support to the side walls as we’d left the joists connected for safety, so we started cutting out an upright and a joist at a time. These walls are only a meter from our neighbour’s walls, so I stood for a good few minutes having a bit of a wobble before doing the first one. It finally occurred to me that the years I’ve spent cutting trees down (an odd hobby but a satisfying one) were of use. Just think of the studs like little trees. Worked a treat. So on Wednesday we went home pleased with progress. I was alone on site Thursday and Friday so it was tip runs to get rid of the fluff bag and wire mountains, and lots more hours of spade work stripping plaster. When on Friday I realised how dusty the site (and our neighbours front patio) had become I quickly deployed the hose to damp the floors down which improved the feel of the shell significantly. I had a day off Saturday, and J and I visited site for J to tend plants and see progress first hand. Oddly, I found not working really difficult. I really needed the weekend off, especially my shoulders, but my head felt I should get in there. As both J and Steve remind me constantly, it’s a marathon, not a sprint, and there’s always tomorrow. But stopping before exhaustion is, I find, very difficult. My body clock has shifted completely now. I wake before 06:00 and lay there thinking stuff through as there’s no way I can get back to sleep even though I’m still tired. We’re still chasing quotes on many things, and it seems in a lot of areas our need for early quotes simply doesn’t fit the industry. We are asking too early, though of course we want the info for both budgetary reassurance or to be able to plan nicely in advance. However getting numbers requires the work to be imminent, it appears. This is even the case with our BCO. He wants all changes from the architect drawn building regs plans authorised by a grown up. Acceptable grown ups include architects and SEs. A good example is the attic. We do not want eve vents, we want just ridge vents and a roof sealed by OSB (sort of sarking). Our architect refused to remove the eve vents as that’s what he’s always done, so we are fortunate that our SE is happy with our alternative plan. All I have to do is draw it up and submit it to Bob, our SE, for approval. I know that’s vital work but as it doesn’t involve a spade it somehow feels less so. Yet another odd thing.

Well, it's been a busy month. I'm taking weekly Pilates to keep my back in check and so far so good. This is the first week I've taken off without any incidents to progress the house. This is the list of what I'm managing currently just to tickle my brain in a years time! Plumbers due to start any day - prep bathroom fixtures - a lot of boxes onsite! Met Electrician to get quote Electrician recommended kitchen design be finalized - booked appointment in showroom Went to get sample of Moso bamboo flooring but they stopped making their natural product. Wanted to use sample to choose kitchen door colour. Contacted the bamboo flooring company so they do ship to Ireland, working out how to get samples and if I'll float / glue and use natural or strand woven downstairs (have a bedroom downstairs to transition between if I mix) I think my foul drainage is connected to the storm drain outlet and visa versa - contacted Irish Water rep to check as plans say I'm right but the smell and sludge says otherwise! Insulation - started Gutex under roof install, walls 90% finished Getting ready to order MVHR but my preferred spot is very busy and could be too tight for all the pipes! Japanese Bath arrived, looks very nice! Bought spa reheating setup and pump Got next bank drawdown after single digit typo held up cheque requisition for a week Cracked a tooth, 50/50 if filling will hold or I'll need removal and root canal treatment! Find out in a week! Installed Rat flap 4" fine but the other pipe appears to be a 6", flushed out pipes with some water. For the external walls (internal buildup) I'm using a 40mm gap and a further 2x6 wall inside. I fill the gap with 50mm rockwool as a thermal break (220mm timber frame) and then add 100mm Moy Metac to hit my U values. I've to use Gutex under the roof in a 60+80mm offset layer with ejot screws & washers and then a 2x4 stud to hold it all in place. Both setups give me a 40-45mm service cavity although the 92mm MVHR pipes will need more carving out of the Gutex when they are installed. I installed Cellecta Screedboard 28 upstairs to provide soundproofing on the floor. You glue these together and leave a 12mm gap around the room edges for some yellow foam they provide. I ran out of boards and had to get some other boards (5) for the landing as I'd miscalculated and they only ship pallets. I also left a 925mm square gap for the ensuite shower. The boards are heavy (18kg each) - I had 42 of them but needed another 5 for the 33m2 area I wanted to cover. I might still add sound insulation between the Pozi joists but for now, I'm happy! My poor car has been taking a lot of runs to the dump lately, offcuts and waste just builds up. I finally got rid of 20 or so pallets lying around so the driveway is clear for work next month. Just need a working toilet to get rid of the tufloo! So, about to start first fix and have a lot of stuff on order / about to order to get me through that. Am choosing Fermacell but can get 2500x600 sizes locally. Finally - I nearly paid the 8K heating deposit to a Nigerian who had got in between the communication between me and the supplier. They asked me to send to a GB CoOp bank IBAN which I thought odd and then followed up that the invoice person was on leave and had I sent the payment yet, everything was ok their end and they were waiting. Luckily I phoned the supplier and we realized what was going on so nearly 8K lost, goes to show! I got lucky as the delay in getting my next cheque from the bank meant I didn't have 8K to send anyway! If something does add up - ring!

Off Grid Challenges Recently, there has been a few people talking about off grid living. This is an admirable and romantic idea, and something I would like to do myself. Then reality kicks in. First we must agree what we mean by off grid. To me it means not connected to main services, but usage of public services i.e. roads, domestic rubbish, healthcare, education, policing, food, clothing etc is allowed. Basically it comes down to water, waste and power. I have come to these limitations because I cannot live without the others. No one want to see me in handmade clothes and washed only in spring water. So the first thing to look at is how much energy I actually use, and when I use it. Luckily I take a keen interest in this and log my electrical data every few seconds (a mean of 8.5 seconds). Internal temperature data is also logged. Initially, to keep things simple, I work with monthly data, but will drop down to weekly, daily and half hourly data when needed. The chart below is the big picture of what I use. Chart 1 I am generally quite happy with my overall usage and internal temperature. This winter I am experimenting a bit with the temperature as my working hours have changed after 15 years of working evenings I have gone back to working days. As Chart 1 shows, January to April shows I have my storage heaters on and use a Mean Power of between 0.7 kW and 0.4 kW, then it drops to 0.36 kW in March, then down to 0.25 kW until the end of October. As you will have noticed, there are two Mean Power lines. One is the ‘normal’ interpretation of the Mean i.e. the sum of all readings, divided by the number of readings. This obviously includes the minimum readings, which are 0 kW and sustained maximum 4.33 kW. ‘Sustained’ in this instance means for at least half an hour. There are times where the Maximum Power peaks at 13.16 kW when looking at half hour data, but this may be for just a few seconds or minutes. By filtering out the 0 kW times, one gets a more realistic idea of what is actually being drawn and when it happens. This is important as it can help when choosing storage and delivery systems. Without changing anything, including usage behaviour, I could get an inverter that has a maximum power delivery of 14 kW and know that all my usage would be covered. Storage, for one day, without any inputs, would need to be at least 26 kWh once 20% efficiency losses are taken into account. The 20% losses are based on a ‘best guess’ as this is a very variable percentage based on different power draws, battery charging and discharging temperatures and the state of charge they are at. So what do I use my energy for. Luckily, being on E7, I can easily see what is used for water heating and what is everyday usage. By looking at my April to November night usage, I can get a fairly good estimate of my domestic hot water usage. Chart 2 Chart 2 above shows the half hourly usage between April and up to November, when there is no space heating on. The mean usage over that period is 4.2 kWh, so apart from the washing machine usage and the fridge switching on, it is fair to assume my daily water energy usage is around 4 kWh/day. This is bourne out my my higher than average water usage. One of my many failing is that I like a bath, every day, and would have two a day if I did not curb my enthusiasm. If I fitted a heat pump, to heat the water, I could probably reduce that down to 2 kWh/day. Or if I took showers, less than 1, but I dislike having a shower, though they are good at getting the day’s fat, blood and grizzle off my body after work. Chart 3 Chart 3 shows the same data, but for January and February when the storage heaters where on. The daily mean, for space and water heating, has increased to 12.25 kWh/day, so 8 kWh/day are for space heating. This works out as a power delivery, for my house, of 27 W.m-2. Using a heat pump could reduce that by a factor of 3, so less than 2.6 kWh/day or 9 W.m-2. Looking at the mean internal air temperature, I see they are within 0.5°C. This is good as it shows that my heating regime is working well and does not need adjusting. So having got my usage figures, and estimated some usage figures if I changed to a heat pump, what can be done about generating energy on site to cover approximately 8 kWh/day. My house is small, and the roof will only support, at the very most, 3 kWp of photovoltaic. It is also less than ideal facing with the optimal side facing South West. Looking at PVGIS to get an estimate of what I could generate, highlighting December because it is the worse month and with similar usage to January, it shows that there would be a total generation of 24 kWh. That works out as around 0.75 kWh.day-1 It is not until April that I could cover my usage, and by October a deficit would be showing. The deficits are in the table below. Month Usage /kWh PV Generation /kWh Deficit January 248 31 -217 February 232 58 -174 March 248 129 -119 October 155 83 -72 November 180 38 -142 December 248 24 -224 Whiles the above energy deficits are not that large, they need to be covered. Even if a battery storage system was installed, without the generation capacity, regardless of how spasmodic the generation, it would still not be covered. The only realistic generation method is to use a small generator. Using December’s data, as it is the worst month overall, on average, a 2 kW generator would have to run for 4 hours a day once efficiency losses where taken into account. During these 4 hours, a battery system of 26 kWh capacity, could be efficiently charged with 8 kWh of energy. By having an oversize battery storage system, more effective charging and discharging can take place, and the system will have a longer lifespan. It also allows for some days to probably not run a generator at all depending on the weather. My choice for a generator would be bottled gas (LPG). While diesel may offer a small improvement in efficiency, they are noisy and if the stored fuel gets some water in it, can be expensive to rectify or repair. Gasolene to LPG is a tried and tested conversion. Ideally a combined heat and power (CHP) unit would be used as these offer the best possible efficiency with about 30% of the fuel input turned into usable thermal energy and 20% into electricity. Unfortunately there are no easily available small CHP units or around 5 kW total output. This would mean that a DIY solution would have to be made. This would be an interesting project. There are some small capacity, water cooled, twin cylinder motorcycle engines that may lend themselves well to this application. There are also cheap, permanent magnet, low speed, direct current current motors that can be driven as a generator. Noise would be the biggest problem with a generator, but as it may only run for a few hours a day, then it can be used during the daytime. It can also be buried in an earthen bank, with secondary inlet and exhaust systems fitted. Modern cars are very quiet at low revolutions, no reasons that a modern motorcycle engine should be any different. My car, and old diesel is quite quiet at tickover, and it is using 1 kWh of fuel per hour. So to conclude, while it is not possible for me to be ‘off grid’, with a larger, more isolated property, and the use of a generator, and about £25,000 of investment, I could be off grid.

I've been out with my back for a bit but now taking Pilates classes and everything feels fine so far. Been crawling around the new attic and installing the Intello membrane and taping for air tightness lying down and in difficult positions without issue. Phew!! I've put a call into the Plumber for first fix and will see when they are next available in 2025. Once they are available I'll book the Electrician. Updates are as follows: Interior stud work for outside walls nearly completed except for open plan area. This is provide additional space for more insulation and a service cavity. 95% of Moy Metac insulation fitted, hope to complete today except for specialized areas (Velux and Oriel Window) 95% of air tightness taping completed except for door thresholds and and Velux/Oriel areas. I've used up my extra rolls of Tescon Vana tape and did a quick run to pick up more from ecological before they shut for Xmas. Needed 2 more rolls, so got 3 !! Very few places stock it and usually I get it delivered but I plan on working on the house over Xmas and needed to have it on hand or I'd have to wait until 2025 to get more! There are some trickier areas to get airtight where studs protrude / the roof intersects, I'm just taping the hell out of it! And using other sealing products to help. The place is a lot quieter with the insulation in place and even though its 3oC outside, the attic work was comfortable as the heat from my efforts is being retained up there! Helps a lot but when I take a break and sit downstairs it gets cold fast and I can see my breath!! Thinking about the outside drainage and have a shopping list as not heard back from groundworker so if I have to do this solo wanted to figure out what I'd need. Tempted to buy now but need to stop distracting myself and work out exact quantities of internal products needed to finish insulation, plasterboarding and to fit out bathrooms I'm the proud owner of three toilets, a wall hung cabinet with sink, tap and led mirror. First time buying any of those! The plan is to get a working bathroom up by Spring so I can ditch the Tufloo outside! I can flush by bucket! So, what a 2024! Slower than I expected but I'm nearly ready for 1st fix and when the trades get onsite they won't hang around. I found an excellent bathroom outfit who can provide a tiler and everything I'm looking for and are local. I plan to let them tackle the main bathroom and all the tiling but may do some of the ensuites myself if I feel up to it! I've used 53 rolls of Moy Metac so far and am the owner of a wide array of power tools. Am proficient in working without main electricity and just off battery power only most evenings (No temp supplies allowed where I am). All the evening work has added up nicely! Best wishes to all planning or executing their projects and hope all goes well for you in 2025!

Not posted an update in a while but was focused on getting the outside of the house rendered, painted, guttered and drill vented before the scaffolding came down. It was off hire on a Monday and I worked 11-12 hours days on the Saturday and Sunday to get through a few tasks including chain drilling the MVHR vents (2) among other things. Basically anything at height. Anyway, while peeling the masking tape off the soffit while lying down on my side I moved to all fours to get up and my back went into spasm! I was still able to move around but the next day it was sore. Off I went to the Chiropractor the next day and he thankfully sorted me out. A few weeks later and I was putting the floor down in the new attic and again lying down while slightly propping myself up to secure the T&G OSB with screws and I felt my back get sore. The next day again I was in agony and off to the Chiro the next day. The following week I took a different approach to finish the attic, very carefully, and remaining standing on the ladder all the time working backwards towards the hatch opening. Thankfully this avoided any further injury and I completed the task. Fast forward a few weeks later and I visited my mum, contracted covid and while propped up in bed the OTHER side of my back went. And this was no fun. No Chiro for me while testing positive (had to wait another 7 days) and it really set itself in. As soon as I tested negative I booked in to the Chiro but despite two visits it was still sore. I could do a 1/2 day at the weekend and a good nights sleep could repeat but it was hindering me. I'd booked 30 x 2x4 and 100 2x6 for delivery this week before the latest episode and had taken the week off work. After they arrived on Tuesday (I insisted on a HIAB thankfully so they could be dropped inside my boundary where I could secure it) I moved the thirty 2x4's inside but felt my back beginning to go again. I lay down but it was getting worse so I covered the remaining lumber and headed home. A few bad days to follow. I tried one Physio my neighbour recommended on Wednesday but it didn't shift the slow, gradual healing along much. I tried Panadol, Ibuprofen, even CBD oil but nothing was helping. I went to a local Physio yesterday and have received some treatment and exercises so I'm resigned to 2-3 months of recovery (my estimate, not theirs) to make sure this is really healed but start Pilates as soon as the Physio says I'm ready. I've been resting up all week and just have to accept I'm the weakest link! In an 18 month project so a few weeks isn't that much but I'd hoped to crack on this week after covid etc. Not to be!! Yeah, so take care of yourselves, especially if you are solo. I've accomplished so much over the last 10 months to get here, it was just one deadline where I pushed my body too hard and am now paying the price. It was a fear of mine but now its here I'm just going to rest, get back to work, wait for my back to be comfortable again (it's still sore) and take things easy for a while (I can plan electrical, home automation etc in the meantime!). How do people in their 60's even do this?!! I'm in my 50's and finding it hard! Fair play to those folks!! Anyway, Off to lie down, I'll call a few favours to get the lumber indoors when I fell I can help at least a little and only tackle jobs when I have a good back regime in place. I reckon it's 8 more months to finish. Can't wait!!!

Week 9 and 10 The gable ladder is up, and the OSB 3 is installed over the rafters. The overhang supports are shaped for the secure attachments and put up. The South side of the roof gets its cross batten. The scaffolding comes down, unfortunately due to miscommunication between the director of the company in the office and the director working on site the scaffolding comes down before the North side gets battened. The builder has given us the materials and refunded us an amount for the labour. It was always our plan to try and get the foundations and walls put up by the same company, so there is no doubt about site measurements. During the tendering process we found it very hard to get a groundworks team who worked closely with a builder where the combined price was what we expected. We had builders who came and quoted then ‘ghosted us’, perhaps they didn’t like us living so close to the build or like that it was only a shell build. One builder put his estimate in for both groundworks and the build but suggested his mates company could do the groundworks cheaper as he had his own equipment, but his mates quote doubled the first estimate. Which left us with little confidence in the builders estimate. Getting a detailed estimates and quotes for groundworks, build and roof became nigh on impossible, and I was quite prepared to call the whole thing off or just do the bare minimum to secure the building works had started. We had still added value to our land and it would have kept our long term options of selling the land with the planning permission commenced. Eventually we found a building contractor who could do the foundations and the build. Although I ideally wanted a dry shell before we took over the project managing, we are parting company with the builder sooner than planned. This is partly due to his inflexibility of using only his choice of solar installer who wouldn’t put the solar panels on that we wanted. The builders solar installer wanted to install 6.52kwp but I had found panels giving me 8kwp and this was better for us and the SAP/EPC. The builders installer kept looking at an outdated list and saying the panels were not MCS certified. The panels only got their MCS certification in July and despite me telling him the MCS certificate number, checking with the wholesaler and MCS that they were ok he wouldn’t change his mind. Due to the builders rising costs we decided we could no longer continue with his company and instead we have sourced our own roofer and solar installer, who will install the all black 500w panels I wanted. This has saved us over £12,000 but delayed work slightly as one lot of scaffolding had to come down on the Friday/Saturday and the roofer will put his own scaffolding up on Tuesday. Total man days of labour for week 9 is 14 days. Total man days of labour for week 10 is 17 days. Grand total of labour from building contractor is 157 hours, this has been recorded by me just for reference it does not include any scaffolding, up or down. The actual cost was on a fixed price quote. Total cost to date. Brought forward £45645 Payments to builder for installing ICF walls, internal load bearing walls, stud walls and roof structure £95000 (ICF £15,000 apx) Total to date £140,645 I have quotes for £20k for the roofer, £8k for the solar and £22K for the installed windows. If this all goes to plan thats less than £200k before internals start.

One aspect of the Passive House PHPP I paid close attention to was overheating risks. As a result we looked at shading and extended the downstairs porch to shade the downstairs bedroom window. The upstairs we though about using Brise Soleil and have 3 canopies over the 3 main windows. I've been working on this for about 8 months with more than half on design and structural engineering and manufacture taking place in June. Then I spent most of July / August trying to get them to fit before bring back the bricklayer to finish some work and the day before scaffolding being taken down, finding I couldn't get the blades to fit....!! So the idea was get briese soleil drawings and have my timber frame SE come up with a plan to support them. This involved extra vertical posts either side of the windows and a big metal "caison" as I call it bolted 360 degrees into the timber structure. I got the timber frame lads to do this bit for me as it was a 2 man job and I'm a solo worker. Then it was over to me to fit the arms. There are two arms per shade with 5 x blades between them. Each arm has a baseplate, a thermal break plate and is bolted through the timber frame and caison and meets another metal plate and then washers and nuts are attached and the whole thing fits together. There were a number of issues, the first was the hole centers for the mild steel caison didn't line up with any of the the powered coating aluminium brise soleil components. Well, Aluminium is an easier material to work with so I used a step drill to enlarge the holes in everything but the mild steel. 1 Arm fitted, then the other. Next a dry fit with with the inner and outer solar sail in place so we can see how we are doing and nope, wouldn't fit! I ended up having to go at the mild steel too but it was much tougher going and I probably only ended up hardening it. Eventually I got the six arms fitted and knocked out the sails so that the brick layer could finish the final course. Last weekend I left re fitting the sails until Sunday, and the scaffolding was off hire on Monday. Not chancing my luck I went at it and found the arms for the longest blades (1.8 meters apart) 30mm too close. It was too far to wedge my body in the gap so how do I solve this. I know it was tight but thought I'd finagle it somehow!?! In the end I figured out how to use a car jack to create the space I needed and managed to get all 5 blades installed this way on all arms but it was a close thing loosing light towards the end. The rooms do look darker but I'm hoping the scaffolding coming down will offset this a bit. Of all the house projects so far, this one was my hardest! Advice: never give up, never surrender, unless it's tea time!

There were 28 cattery pens and an office building to get rid of. We really didn't want to have to pay to have this removed, so we put an advert on Facebook, and were inundated with calls. We sold the lot for 2.5k and after 3 days of removing the roof structure (didn't want to risk people falling through it), the buyers came and removed it. They left a complete mess, but I spent a further three days putting the remnants in one 4 yard plasterboard skip and 2 * 10 yard skips. This meant we were still up 1.5k, so not a bad result. Pictures of the site before clearance and afterwards. The next task is to hire an excavator and break up the masses of concrete slab. Hoping that it is not reinforced so that I can hire a crusher and recycle the waste into hardcore.

We moved from Manchester to Cornwall 6 years ago and we are very happy with the overall location. Our existing converted barn, was converted by the previous owner and is very nice but is built on three levels and has 4 double beds, kitchen, dinner, lounge and snug and 3 baths so it is far too big for us when we retire. When we bought the house I always say we chose it for the working barn apx 300m2, not the barn we live in. We are building for our future in the hope that we can continue to live her a long time, if it takes us 10 years to build we will be 65 when we move in. My husband has a history of bad backs a bungalow with no steps and easy access is high up on our want list. More recently our Greyhound is refusing to go down to the snug in the lower ground floor at night preferring to stay upstairs in the kitchen. He is incidentally another reason we bought the property, two fields he can run off lead. We don’t want anything too large, a well insulated bungalow that will be cheap to run and maintain. We have a small cow shed on our land and although our property is listed the cow shed is outside the curtilage of the property and built in the 70’s so does not require any listed building planning consultations. When we purchased the property a new build was never on the agenda, but it is now. In September 2021 we engaged the services of a planning consultant with a view to demolish the small barn and replace it with a new build, his view was favourable. In January we then approached an architect who suggested full plans would be best since what we were asking for was in keeping with the surroundings, not that much larger than the existing barn and since it was visible from the listed property more detail such as windows and cladding would be required. Two months of absolutely nothing happened then in March we met up to discuss our requirements and finally in May we submitted our plans. In June we had our necessary bat and bird nesting survey, the gentleman who conducted the survey nearly started looking at another old stone barn until we corrected him and he then told us that bats wouldn’t like the old cow shed as it would be too hot in summer (tin roof) and too cold in winter due to the holes, drafts, and thin wood walls. Then in August we had the Phase 1 preliminary risk assessment, required because we were previously farm land. From the survey I learned that in 1884 there were two wells 165m W of the site another 580m SW of the site and two quarries quite a distance away and in 1906 a smithy in the village, no surprise there as there is a house called ‘The Old Smithy” . The geological map indicates that the site is underlain by the Bude Formation - Sandstone. Sedimentary Bedrock formed approximately 310 to 319 million years ago in the Carboniferous Period. The report was very detailed but returned very little about the land the barn is occupying, that a visit to site wouldn’t tell you. Nothing bad was reported so we were happy and we continued pushing more paper around. Eventually its our turn for the case officer to look at us in detail and we get conditional approval in mid October 2022. Mid March 2023 and we have submitted our building regs drawings and my Part O Spreadsheet, window amendments to the planning department and the SE has quoted and is starting on his work. We are over 150m from the fresh water main so will need chlorinating. I found a great guy who has dug the first trench for the Water, Electric and Openreach, he will return when the new build is ready for the second trench to install the services into the house and will then chlorinate the pipework. Site electric is in from the pole in our neighbours yard towards the Old Cow Shed. We were offered a good price by National Grid for 3 phase, they would have struggled giving us single phase due to lack of supply network and another new build close to us in the village has gone off grid because there connection fee was too expensive. We wanted 3 phase any way as we hope to fill the roof with 30 solar panels facing SSW with no shading. As soon as it warms up and the field is firmer we plan to start clearing the site and moving the spoil down the field into our larger field. Doing it now would be like making a mud bath. Sometime between October and February we will demolish the barn and this time next year the new ICF build will go up. In the meantime lots of planning continues and I’m going on a short plumbing course. The husband is an Electrician by trade and can do some plumbing but hates getting down on his hands and knees now. Last year I tanked and tiled our existing en-suite and have learned all about wet wipes and silicone so another job moved from the husband to me. 😀 The main photo shows the site electric and the drive leading up to the cowshed to the left at the end and just on the edge of the photo are the old stables used as workshop storage each stable bay has a different items stored. A new entrance to our field will be made diagonally from the site electric to the left of the old cow shed which will make our farmer happy as he currently has a very tight turn left just in front of the cowshed. He comes twice a year to cut the grass and in return he usually takes at least 15 round bales away. The other images are from the architect but are already out of date. To pass Part O we are submitting an amendment for the removal of 4 windows on the North elevation and replacement with 6 roof windows that offer more ventilation.

After removing the old heating system a couple of weeks ago, the engineers arrived at 10am Monday morning last week - waiting for the delivery of all the 'bits'! We'd installed a couple of electric oil filled radiators for mum and dad and luckily the weekend was mild. The lorry arrived around 11am, things were unloaded and taken into the back garden, then the guys all disappeared to go and get the pipework..... So after lunch, back the 2 chaps came and installed the ASHP into the back garden, with pipes into the roofspace. (one lives in Stamford, 2.5 hrs drive from here! - no wonder it took a while for them to arrive.) Tuesday, we had 3 guys, ftting the radiators into the place. I was told the electricians would be there thursday and friday to connect everything up. Wednesday 3 guys again, all sorted of things were now fitted into the cupboard and the radiator installations continued. There were 2 under bench blowers in the kitchen as there are no walls for a radiator. They were fitted but not connected - needed an electrician. Two radiators had to be removed and replaced as they had faulty paintwork (nice to know they arranged that themselves, we didnt have to complain). Not sure what happened thursday but no electricians turned up. 🙁 Friday, 2 electricians arrived and started to connect the system. But then one said they had to leave at lunchtime! I was not impressed but to be fair, they carried on, until the system was up and running. I had a quick explanation and off they went, around 2pm. The house was lovely and warm with hot radiators! Yippee. 😁 Saturday as I drove to a friends many miles away, we had a call from the parents - they had no heating! Grrr. But after emailing the 'boss' - within an hour, he arrived at the house and sorted out the problem - air in the system. Heating resumed. 😄 Sunday - Mums 85th birthday. House toasty and all happy. 😁 Dad mentioned a problem with his bathroom radiator which was so cose to the door that it could only be opened half way. email sent to 'boss' who arranged for an engineer to come MOnday. Which he did (from Stamford), he moved the radiator (cursing the idiot who placed it there) and fixed the fronts onto the under bench heaters. All looking good. Tuesday - unknown to me (they didnt tell me), there was no heating again and the 'boss' was called by Dad. He arrived after an hour and got it working again, telling them it was all sorted. But today, wednesday, when I arrived at 9am, the house was cold. Arghhhh!!! After emailing the 'boss' who arranged for his business partner (the elctrician from last week) to ring and come out. In the cupboard, the box which seemed to talk to the thermostat was flashing amber - and not sure that was right, i pressed a button and it turned flashing green. But still no heat after half an hour. I then found a manual online for the thermostat - Drayton Digistat - from which i discovered it had been set to a particular schedule for those out at work all day - ie on for a couple of house in the morning, low during the day, warmer for the evening and off at night! Not ideal for two 85yr olds, at home all day. After installing the app on the tablet - didnt work - and then on my phone, i was albe to amend the temperatures up to 21oC from 6.30am to 22.00pm with 16oC at night. I could see the Digistat registering that change and start the heating symbol. but the radiators stayed cold and the temperature did not change from 17oC. The electrician rang and I told him about the flashing light. I was told to press it till it was constant green which we did. And then i heard the pump start and water could be heard moving. But still no heat. After a couple of hours, he arrived and confirmed that while the App was controling the Digistat, they were not talking to the bix in the cupboard. After some work and a call to the Manufacturers, he re-set the system and everything seemed to be talking to each other. I was able to boost the temperature with the App and the house started to warm up. So thats the current situation - its taken several visits and several days without heating but fingers crossed, it continues to work. When it does work, the place is toasty, and I have to admit that all the guys have been great with mum and dad, moving out the way when needed, and being polite/helpful. And the 'boss' and Electrician have been quick to come out and try to fix the problem. I just hope there are no more calls. Will update in a few days.

Apart from the “picture from the mound” timelapse blog entry, there’s not been much of an update since mid September 2022. So, get your preferred hot drink (maybe a SteamyTea), and settle back for the next instalment. Where were we? SWMBO was still in recovery from her foot infection - you remember? The one that might have killed her? The second floor ICF had been installed, and the concrete poured. I’m still going to spare you any pictures of the foot, but here is a concrete pump truck instead. So, next on the list - a roof please. But before that, the final steel beams had to be installed [FX - thumbs twiddling in the foreground and whistling can be heard as we wait for the steelworker once again], but it wasn’t too long a wait, and by mid October 2022 we had the beams installed. In late October and early November I set to work with the ground worker to do some backfilling, and of course on the days I chose to have the digger onsite, Cornwall delivered some of its traditional autumnal weather so any attempt to properly compact anything was nigh on futile. In the meantime, more joists, endless sheets of T&G OSB, vapour barrier, 160mm deep sheets of PIR insulation, and some of the biggest screws are readied for ordering. The joists arrived in and in early December I had my supervisor and client (SWMBO) back on site 🙂, and she has graduated to being a mountain goat. She now refers to the site as her "happy place", even though we have a strong suspicion that the infection was started by a visit to a local beach. By mid April, with help from some now local family members, we’d installed the roof joists, and in mid May we were ready to start boardin’, vapour barrierin’, and insulatin’. The GRP was installed in mid July 2022 (by others). I’d also been readying the Great West Wall (GWW) to have the triple glazed sliding doors and windows installed (by others), and this took place in mid August, just in time for my significant birthday. There were some fitting errors, but I have to take my hat off to the installation company, they have been back to rectify their work, and have supported me with making the suppliers change some of the sliding door fittings as they were just not correct despite their protestations. In October, we had the mains electric and meter moved from their temporary location to inside the house. Over the ensuing autumn and winter months, we’ve been installing some of the final internal partition walls, running water pipes, installing more insulation around the GWW windows, and recently started on the ventilation ducting following some core drilling being undertaken (Tip: always ask for a hole to be drilled that is about 10mm bigger than you need - expanding foam is your friend. I donate my scar tissue to you all 😂) In December, I got made redundant. No worries, this may actually be a blessing in disguise. Next up on the list: Finish ventilation system Finish insulating the GWW Finish backfilling Electrics Floors Walls ASHP and HWC Kitchen Bathrooms The remaining plumbing Outer wall coverings But, in the meantime, we have the small matter of our daughter’s wedding. DOES SHE NOT KNOW WE’RE TRYING TO BUILD A HOUSE!? (Time to end: 2 years 🙂 )

I thought I'd publish some rough figures for the running costs for 12 months. Details. 85 Sq M bungalow. North Scotland -highlands All electric (heating/DHW/cooking and running * two self catering cabins) 4 kW South facing solar panels. 0.88 ACH EPC A103 Heating set to 20⁰C DHW set to 43⁰C Year to date: Total Electricity usage 3300kWh ASHP usage 890kWh heat and DHW don't know if Samsung gen6 can split the usage? Solar Generation 4254kWh Solar export (given away) 2359kWh. I'm happy with the house, and the heat retention seems very good for our budget build. Heating hasn't been needed since mid April, and has only been on around 6 days this autumn. Obviously my biggest issue is reducing our solar export. I have done nothing in this regard with the exception of manually loading shifting washing machine / drier / dishwasher on sunny days. My issue with solar diverter is that the meter is located 50M from the house (in an enclosure) the house is supplied separately from the cabins so I can't just monitor the house as the cabins maybe using power. I'm in the early stages of exploring using ESP-Now as a CT clamp monitor and building a diverter similar to how @ProDave and others have done. How do these figures look? *We had around 170 days of cabin usage which use electric for cooking/heating and the laundry.

I really hoped that now we are progressing after our suspended floor saga that things would get better, but something somewhere is determined to make sure that doesn't happen. The only change is that this time the things that have gone wrong are not build related. Firstly, my brother, only 63, died of a heart attack with no history of problems. I spent 5 days with him and his wife / kids in intensive care hoping against hope that he would pull thorough, but at 6am 6th Feb his heart gave way for the last time, no more restarts, RIP Alan 😞 Just before that, 6 days before, I got told that I've been made redundant, as the only breadwinner that's another major blow, the build funds are sorted, but we still need to eat and pay the bills and run the cars. So, forget build PM I'm now looking for a job that offers enough for us to live on. The only snifter I've had would be a 20k reduction in pay with an hour's drive each way and 24hr on call once every 4 weeks. I may be desperate, but I'm not that desperate yet. The trouble is I'm in my 60's so although age discrimination is illegal you can't prove it's happening. But, with ALL the experience on my CV it shows that I'm not just out of uni. Right, back to the build. In December we had just got the details about our suspended floor. It had to have a bearing of 130mm, plus 20mm expansion foam, plus shear links. After much huffing and puffing it was prepped and ready for inspection. The BCO came out and just said yes with no hassle and went on to talking about the other parts of the build and our future under pinning of the back wall. He was really helpful and has even sent a message to the SE saying that he feels that 2.5m deep foundations is over the top with our sandy soil. He wants us to dig two trial holes of 1.5m deep and then have a site meeting with BCO & SE to discuss what we really need. He feels that the SE is being over cautious bearing in mind we are converting the barn into a single storey bungalow when there have been no issues with the existing barn over the last 70+ years. This will all happen about March as hubby is going to build this 'room' first. This will actually be our hall and snug. The above is the inside wall of the cavity wall up to DPM. As I speak the mostly external wall is finished although the bit nearest stays internal as that borders the kitchen. I wanted a 'proper' wall for hanging a sliding door and kitchen cabinets. It was already a separate space when it was a barn so it is a bit like an extension. The long awaited concrete pour happened, at one point it looked like they might not make the slope as it was raining, but after a lot of slipping and sliding they got there. bit of a wet day for it, but all dry now The only other thing we did this month was buy a block saw at auction (for not a lot of money), it needs a new engine as it's been stood outside for years, when hubby took off the old casing it was obvious just how long. This is how it arrived and this was what was under that casing. I wonder how many years the birds were nesting. We actually got 2 for the price of one, when we got to the auction to collect they said, oh there were 2 of these in a lot. So, hopefully we can make a bit of money by cleaning, replacing the engines and servicing. These beasts are seriously expensive to buy working at about £750. Hubby has worked with a company in the paste who are going to do the work for us and refurbish so we should end up with at least one working machine for less than £250. I've not been able to work for over a week on the build and we stopped for 10 days over Xmas so a very short month. Once again, I'm just hoping next month will be better, but somehow I'm losing hope on that front.

As I've previously discussed we have an MBC Passive Slab and Timber-frame, but unlike most builds, our house also has a very traditional stone cottage-style exterior because the new build sits between our current farmhouse, which dates back over 400 years and a cottage which dates back approaching 200 years, so our planners required that we use the same local quarried stone. So a topic that often comes up is "how do we do the window / door treatment on a timber-framed house with an exterior stone / brick / blockwork skin?" In this blog entry I want to describe how we approached and addressed these issues on our build. Whilst I make no claims about our approach being the only or the best one, Jan and I do believe that this has worked well for us; we are pleased with how it has all turned out and we don't think that we would do it differently if we were doing this all again. So if you are in a similar situation to us, please consider this as one possible approach. There are a number of issues that we considered in designing our detailing: Decoupling the inner and outer skins. In order to achieve thermal isolation of the inner passive slab, MBC also lays a separate outer ring beam for blockwork, brick and stone skinned houses. The inner slab carries the Larson trusses of the MB twinwall frame, and the outer ring beam carries the stone skin. The inner frame is CLS; the outer stone and mortar, and these two have different expansion characteristics so you should anticipate up to 5mm, say, differential movement between the inner and outer skins. So we decided that we should not use the window and door furniture to couple these. Closing the gap. Even so, we still have the issue of the 50mm nominal air gap between the inner and outer skins and how we close this for weather protection and cosmetics. Our solution to thee two points is to move the front of the windows some 45mm forward of the outer surface of the frame. The stonework then sits immediately in front of this,overlapping the window frame by some 30-40mm. Fixing the windows and doors. We have Internorm KF200 Aluclad PVC windows and I agreed a fitting profile with both MBC and ecoHaus SW who supplied the windows. This comprised a box section (something like marine ply would do here) that framed each window opening at the top and sides as follows. there was a 10mm filling gap for fixing the windows there was a 15mm filling gap at the top ditto the windows had to sit hard at the bottom, but I inserted a 44 × 38 tanalised carrier to lift the base above the internal frame base. This was to give adequate clearance to fit the internal cills. Protecting the windows during the build. EcoHaus SW fitted the windows on day 8 of the the frame erection, so by day 9 we had a completely weather-tight and lockable house. The windows had to be in place before erecting the stone skin, and so needed protection from the stone erection process. The solution that we agreed with the ecoHaus technical manager was very simple and extremely effective and one that I would suggest to anyone else doing this. We simply covered the windows in heavy grade clear building polythene, and this served a dual purpose: It provided total protection against the muck and dust of stone erection. You need a slip surface between the aluminium cladding and the stone skin. (Cf. the first point) The PVC does this. Once the stone skin was complete we simply cut around the PVC on the mortar line. All that is then needed to achieve a total weather seal is to run a thin bead of sealer at the join. Minimising any bridging impact. The windows have fire-break socks around them which acts both as insulation and a gap closer. The doors require special treatment. Here prior to slab pour, we had the MBC team cut out 50mm deep slots at the door openings and we placed extra shuttering in to extend these out by some 40mm in front of the outer frame line. These were rebarred and when the slab was poured, these became a 50mm deep concrete tongue that extends out to the front face of the door opening. The doors then sit on a 30mm upstand on these tongues. The upstand acts as a thermal break, but to minimise any bridging through the tongue itself, we used FoamGlass structural bricks to isolate the tongue from the outer cill and the stone skin. If you do the 2D thermal calcs (or at least I did), the thermal capacity of the stone face overlapping the face of the windows materially mitigates the extremes of the temperature variation, and whilst there is a little uplift in the Psi-factors for the window, in absolute terms this equates to adding an extra ½m2 of glass to the house overall, and not enough to cause condensation risks Maximising internal light. Our old farmhouse has thick stone walls with window reveals and these work well. So we decided to ask MBC to do a similar treatment in our new build. In short not only do they work, they work brilliantly. They let in perhaps 10-15% more light than deep squared frames and they help open out the rooms. They are an extremely attractive feature and both Jan and I would recommend them to anyone considering using a twinwall frame. Here is a picture of the slab during the pour. Note the trays for the kitchen French windows and the back door. Here are a couple diagram extracts showing the window treatment and detailing: and some photos of the wall in construction showing the set forward windows and the finished effect (less the porch that still has to go in.). and an internal shot of the kitchen window detail showing the angled reveals:

So it's mid-2019. After 4+ years of trying to find an 'oven ready' place that suited us, we finally gave up and went the alternate route. Build our own. Found a bad house in a great location. Main downside was the small garden, but you unless you're absolutely loaded you can't have it all. And of course the real estate agreed with our timelines. "Yes, if you buy in may 2019, the design will take you into december, and you can probably start early Spring, and maybe even be done before 2021." Seemed reasonable at the time. * just a small note, I'm not advertising this blog for now, I have no idea if I can muster the willpower to truly build it out, I have a lot on my plate. Let's see what happens.

Results for us as they come forward...(and not what I expected) Our Cool Energy inverTech Air Source Heat Pump CE-iVT9 4.3kW-9.5kW has been on standby only, for the last few weeks, and I have measured the power consumption. It appears to use about 0.1 kWh an hour. That's about 2.25kWh a day in 24 hours. We use a Solic 200 to direct our excess electricity produced by the PV to the hot water immersion. Whilst the Solic way of heat the hot water uses more energy, because it only runs using power we would otherwise give to the grid, its better for the bills to turn the ASHP off all together rather than use it to heat the hot water tank. You would think that with a high COP it would be better to use the ASHP but with the other things on in the home and the car being charged, you can never be sure your not buying all the power. Secondly I think the ASHP runs at a minimum of about 1.5kW when heating the water. The Solic can use any spare power from the PV: 10 to 3000 Watts. We could turn the ASHP off altogether and on only when we need hot water and I have decided this is a bit fiddly so won't do it. Another benefit is the fact that the hot water tank is set to 70C ( the ASHP will only do up to 60 and that is at its least efficient) and this lasts us at least 2 or 3 days before needing to be heated up again! ( We do have a super insulated tank) Days when it could be cloudy and we would have to pay for the power. ( We will turn it up higher in the winter and use it as a thermal store for night time warmth...) And finally I would rather wear out the £50 immersion than the £3180+VAT ASHP! Good luck with your project. M

As we are in difficult times for installing or using anything Russian-related , i obviously went full blown politically correct and installed a Gender Inclusive Austrian Cladding "Der Holzbau" but "Die Verschalung" https://tintabernacle.blogspot.com/2022/04/start-cladding.html

It's been a while since we obtained planning permission and my last blog entry but we've not been idle. it seems that the last 3 months or so have been a constant stream of decisions that need to be made to get this project started. It's also been a period where money seems to be going out but we don't have much to show for it! The majority of the decisions have stemmed from the architects needing to get the detailed BC drawings finished. here's a nice summary of our decisions so far (although I've probably missed and forgotten a few) Timber Frame Company This was a one of the biggest decisions for us (windows and doors was the other) and was the one that had to happen as soon as possible after getting planning permission so that we could get the timber frame designed and the BC drawings created. We previously had quotes from 9 on the original plans before we had to make changes to get through planning. Of these one was discounted as they never got back to me about changing their set specifications, one because they wouldn't use metal web joists insisting that they only used I-joists, another due to extortionate costs and one more because of costs although not as excessive the ones that made the shortlist but just enough for us to make an easy decision not to include them. That left 5 for us to get updated quotes on the approved planning documents. We are going for an open panel system and I will be fitting the insulation to help reduce costs; even though this will extend the build time the savings are substantial enough to justify it. With those quotes we discounted another due to their location and narrowed it down to 3 local companies and MBC. MBC were by far the most expensive for an open-panel TF but they get such good reviews on here and we have friends that are using them we couldn't discount them out of hand, but in the end we couldn't justify the extra cost when we weren't getting from them what they excel at, i.e. factory fitted insulation and promised air tightness levels. to give them credit they were completely upfront about it and completely understood the decision. So that left just 3 local-ish companies to choose from. We visited sites from each company to see their work and after that, although it wasn't easy, there was one clear winner and that was Flight Timber (https://flighttimber.com) based in Essex. We were very impressed with the quality of the build we visited and are very happy with how they've conducted themselves during the negotiations. So we signed the contract and paid a deposit. Since then they've been doing great work in getting the TF design done and liaising with the architects to finalise everything. That has now been completed and it's all with the structural engineer to do the basement/foundation calculations and drawings. Structural Engineer For the structural engineer we had 3 quotes from firms that the architects use, one from a friend of a friend and 2 from recommendations from the buildhub hive mind. We are having a basement and so this was a consideration and needed someone who could provide us what we needed. One of those requirements was an insulated slab foundation under the basement and the arms of the house. There was quite a discrepancy on costs between the 6 quotes and a couple were easy to discount as they were so much more than the others. So from the remaining 4 and after much consideration and communication we decided to go with TSD as they have a great reputation for insulated slabs, are highly recommended by many on here and their price was very competitive! So far, they've only been working on the design since the start of the week, I've been very impressed with the communications and their open-mindedness to my ideas and requirements. I made a decision (doesn't really require it's own heading) to ditch the idea of using block and beam for the lid of the basement and will be using hollow core precast slabs. Sadly though, after the SE spoke to a supplier it was obvious that they wouldn't span our basement at a reasonable thickness without internal structural walls (which we were trying to do without) and so we've resigned ourselves to having load bearing walls in the basement, otherwise costs could easily have gotten out of hand by going for thicker precast slabs, thicker foundations and thicker external basement walls to all accommodate the extra weight of the thicker slabs. so be it, I'm sure it's not the last concession we'll need to make to save money. Civil Engineer we are creating a new entrance to our plot from the road that will go over a ditch and so requires a culvert. so we decided to hire a civil engineer to plan and manage that, the drainage, driveway levels and water course discharge. we only got 3 quotes (it's my magic number for quotes) all from companies that the architects deal with and simply chose the one that wrote the best proposal and the costs were reasonable trusting that the architect's recommendation for each company was good enough for us. Windows and Doors This was a huge decision for us and caused a lot of brain power to try and work out who best to go for with spreadsheets being created to compare the various companies. We have a lot of glazing (about 120m2) and we want triple glazed alu-clad units. We approached 7 companies initially, visited lots of self-build shows to get a feel of the windows to help us to decide. We did consider IdealCombi for full alu windows but in the end our desire to have timber internally won and we didn't proceed with them. We discounted a few others due to costs and in the end it came down to Internorm and Norrsken. Internorm windows are so nice but they are so expensive; despite this we thought we could potentially justify the extra cost but the reviews of the supplier on here put a dampener on them as the last thing we wanted was to pay a load of extra money for windows that we didn't get any sort of support for when things go wrong. We visited the Norrsken showroom in Poole and were very impressed with the windows, doors and sliders and I couldn't find any bad reviews on here for them. The price was very good and so we signed on the dotted line and paid our deposit. We are very happy with our decision and the money we saved over going with Internorm will pretty much pay for our kitchen! External Blinds With all the windows we are having I was worried about overheating, especially after reading some of the issues other forum members have had with solar gain. We needed to make a decision on these before the TF design was completed so that they could be built in to the frame and are then hidden from view. So, external blinds were on the cards and needed to be researched and a decision made posthaste. I've posted elsewhere about my experiences with Roma blinds so I won't repeat that here. In the end I came across Warema blinds which look good and seem to do what we would need them to and found 2 London based Warema suppliers to get quotes from. Both were so similar in price it was hard to choose between them. In the end, after my company house checks (which I do on all people I wish to do business with) it looked like one of the companies had grown their business really well over the last 5 years when looking at their accounts that I decided to take a punt on the smaller guy and went with Corner Star Aluminium. Only time will tell if I made the right decision on that one. MVHR This is a subject that I have done a ton of reading on here in the forums and also posted a few times on the subject. the whole 1 or 2 unit debate is real but I really would like a single unit solution. I got 5 quotes (one through the architect and 4 off my own research). BPC wouldn't do a single unit saying that the largest unit they do is for a 350m2 house but our house is 450m2 and so we need 2 units. I felt that they're just sizing on Part F calculations and the manufacturers own statements regarding house size for unit size and didn't take running at Passivhaus levels that most on here feel that running their MVHR units at is fine. Also, they do sell bigger units, e.g. the Airflow DV245, so they could do a single unit but I just got the feeling that they couldn't be bothered to consider another option. so they're not getting my business. CVC were just too expensive and I didn't trust the company the architects asked to quote as they didn't give any details as to the ducting etc that they'd use (and also were selling a 2 unit solution). so it came down to PAUL Scotland and Enhabit, both of which were offering a single unit solution (Zehnder Q600 with 90mm ducting). Pricing was very similar so in the end it came down to location again (although a price reduction did help!) and Enhabit won. the deposit will be going over today and then they can crack on with the design. Others I'm sure there are loads of other smaller decisions we've made, like external finishes for the discharge of planning conditions etc, and I know there will be hundreds more to come as we move forward with the build including ASHP, Solar PV, UFH, DHW, RWH, floor coverings, tiles, lighting, home automation and so on. The next big decision will be the groundworks company to do the culvert, driveway, foundations and basement. Once I have the SE plans and designs I can approach the companies I've shortlisted to get detailed quotes and can carry on with the decision making. I have ended up having to make a list of decisions to be made there are so many. that way I can tick them off when they get done as it was getting to the point that it seemed they were never ending. at least this way I can see what has already been done and can see the list getting smaller as we progress. thanks for reading. ?

Why is it so hard to get planning approval? Such a simple thing is mired in bureaucracy, pettiness (at least perceived), personal interpretations of the planning policy (e.g. the definition of disproportionate to the existing building) and, in some cases, pure incompetence! One such example was from Southern Water who said they couldn't approve the proposal with a sewage treatment plant and we had to apply for connection to an existing sewage system. err....the nearest sewer is about 200m away as the crow flies over roads and fields that aren't owned by us! none of the houses in our hamlet have mains sewage and we even have an existing Klargester which we will simply be replacing with a new version. so why would they say that we need to connect to mains sewage? crazy. fortunately, I got on the phone and a few weeks later I got a call from someone who actually knew what they were doing and eventually got an email saying that using an on-site treatment plant was not an issue. Then we get to the highways agency. we're asking for a new entrance off the road as it's more practical with the way the plot is and where the new house is going to have it rather than use the existing entrance that is shared with our neighbours. We submitted the visibility splays (although the architect forgot this initially and the first letter from the highways agency was asking for them) and the response we got was basically, how can we put a new driveway in when we don't own the (approx. 1') of verge between the adopted highway and our land and also we needed a traffic survey for the road as it's national speed limit (albeit a single track road so no one could get or does get above 40mph). I got our solicitor on the case about the potential ransom strip and he's sorting that out so we pointed this out to the highways agency and also submitted the existing visibility splays and showed that the visibility of the new entrance is better than existing and so the highways agency eventually agreed to the new entrance and had no issues with the application but did stipulate some conditions. This whole thing took so long that we had to grant a 1 month extension to the decision date. It wasn't all bad though, the Parish council didn't have any objections but did raise a concern about the flat roof as there's a policy against flat roofs in our parish apparently and we had no complaints from neighbours as part of the consultation period and even had one lovely neighbour who wrote in support of the application. so, with all the above done and no issues it came to the planning officer being able to view the application in its entirety. We really weren't expecting too much of an issue here as, although the footprint was quite large, we were adding an annexe for my mum and figured that would be considered as a separate entity to the main house for footprint etc. also we have planned a basement but that also shouldn't count to the footprint. we thought we might get pushback from the ridge height as the outlying planning was for a chalet bungalow and we submitted for a 2 storey house with a pitched roof. So we were shellshocked when the architect said he'd heard from the planning officer and said that the gross internal area (GIA) was too much and we'd need to lose the basement, studio (the room above the garage) and the garden room and also shrink the annexe! wtf! we honestly couldn't believe it. Our initial reaction was to comply and then build the garden room and convert the garage loft post completion. but after thinking for a bit I decided not to capitulate and that we would fight it and so hired a planning consultant to fight our corner for us. we have since supplied to the planning officer the potential size the existing bungalow could be if extended under permitted development with an 8m deep rear extension along the entire length of the property and a loft conversion. with these figures it shows that what we intend to build isn't actually as much of an increase as the planning officer officially thought. hopefully common sense will prevail and he'll understand what we're trying to achieve here and that we don't want to have to have buildings in the garden to get the space we need but want it all under one architecturally designed roof that is sympathetic to the surrounding woodland. if it doesn't though and he's still adamant that the property is too big then we have a list of potential reductions that we're willing to do. And that's where we're at with the planning application at the moment. there's another extension in place until the middle of June so hopefully we can come to some sort of agreement to get the house built. fingers crossed!
