Yes, we moved into our new house on Monday last week, pretty much 9 months to the day since we broke ground and 15 months after we purchased the plot. We know we’ve been very lucky with our build. The weather has generally been in our favour and we had no supply issues or delays. Above all, we’ve had some excellent people working for us without whom we could not have achieved the build. There are too many stars to mention here but if you look through the blog you will see them all get a shout out for their excellent work as it happened. Ahead of the move, Mrs P. did a superhuman job getting everything packed, and the move itself went relatively smoothly, with dry weather and no mishaps. Amazingly, Mrs P. also managed to unpack most of those boxes within a few days, though we do still have some residual boxes to deal with in due course. Moving in day: As we all know, moving house is always a stressful business and moving to a new house is no different. But it is a relief to finally get in - there is always the nagging fear that some disaster will strike at the last minute while the house remains unoccupied. But of course, all was fine. Is our build complete? Not quite. We have some minor electrical and joinery items outstanding, both inside and outside; we have the garden landscaping well under way but some distance from completion as you will see from the photos below. Beyond that, there is a list of jobs of the sort you’ll have following any house move: curtains, blinds, wardrobes, shelving, etc. - but these are ‘house move’ rather than ‘house build’ tasks imo. We do still have to obtain Building Control sign-off and there’s a VAT reclaim to do. On the BC front we had our ‘As Built’ air-tightness test performed by Richard Harris of Peninsular Energy Compliance this week (highly recommended). The result is 1.16m m3/m2 at 50hPa on the envelope basis. Virtually the same figure for Air Changes per Hour , as our envelope area is 583m2 and our volume is coincidentally 580m3. We are very happy with 1.2 ACH. Air-tightness test under way: We have been in the house for a week now and we are really happy with the way it feels and works for us. It’s warm, draft-free, well-lit, quiet, and comfortable; the layout and spaces are working just as we hoped. We are both sure we are going to really love living here. The plant room is (to me) surprisingly warm, running at 25-26 deg C due presumably to the amount of heat-generating equipment in there. I raised this as a separate Build Hub topic but the consensus seems to be that it's not an issue, so I shan't worry. As a side benefit, it does make a splendid clothes airing room. https://forum.buildhub.org.uk/topic/46744-hot-plant-room/ Energy use The combination of solar panels, batteries, ASHP and insulation levels seems to be working well - in our first week we used 0.7kWh from the grid and exported 63kWh. Not bad for February. I need to work out our best tariff option but that’s a job for the future. Enough talk, time for some more photos (some taken just before we moved in)... Kitchen/dining/lounge: Hall: Bathrooms - master ensuite: Shower room: Guest ensuite: Bedrooms Master bedroom: Guest bedroom: Bed 3 / hobby room (Ok, so we still have some unpacking to do.) Landscaping - plenty to do yet. The layout is literally as clear as mud to me... I'm sure it will all be fine in the end(!) And finally... Troy likes the new house - it still has yogurt pots that need licking out Dashboard: Contractor days on site this past two weeks: 15 Contractor days on site since build start: 587 person days That 587 days is well over the 500 days which requires HSE being notified of the build using form F10 (which we did). HSE have not spoken to us or troubled us at all and the F10 notification is simple and costs nothing, so I would recommend any self-builder do so - if you are unfortunate and have an incident it’s surely means less chance of getting into hot water if you registered properly. Budget: I confess that in the final weeks we have gone a bit beyond our self-imposed budget contingency and dipped slightly into savings, but that is really down to choices we have made about the quality of the fit, e.g joinery, kitchen, bathroom equipment etc., and also the extent of the landscaping we have chosen to do. We could probably have remained well within contingency had we needed to but luckily we had some leeway. Plan: We did it! Conclusion: Overall, we set out to use the entire proceeds of our previous house sale to buy a plot and build a better house, and we believe we have achieved that. Thanks once again to all the dedicated and skilled people who have worked on our house and made the build a success. Especial thanks to Mrs P. who indulged my yearning to do a build provided brilliant design input and kept the whole show on the road throughout - a truly wonderful person! That then dear friends is the final blog! Thank you for following us and for your kind words of encouragement and support through our project.

I’ve got to be honest, there are times when it feels like we are inching towards the finish line ever more slowly, with lots of jobs nearly but not quite done. Pulling together this regular blog is really helpful in that respect: Every fortnight I start off thinking there is hardly anything to say so it’s probably not worth issuing an update. But once I start to look at what’s happening since the previous blog I realise that we have generally made good progress. And indeed it’s a case of more good progress over the last two weeks. It does now feel like we are nearly over the line. Several long-standing activities have been closed off thank goodness. So here are some of the things we’ve made progress on since the previous blog. (Confession time: I meant to take more photos of the bathrooms, kitchen and lighting but seem to have forgotten to do so, so you’ll have to wait for next time for those.) Bathroom After our disaster last time with the wall hung shower toilet, my brilliant brother came back over from Sussex to hang the replacement, even though he had managed to break his foot in the meantime - that’s what I call dedication to the cause! The (revised and up-to-date) instructions we were given with the replacement WC pan said to tighten the wall bolts to 7Nm torque. Which seems really very low - the sorts of torque used on bicycle parts. Anyway, that’s what we did to the best of our ability. It was just about enough to stop the toilet feeling at all wobbly and the good news is nothing cracked, nothing fell on the floor, and the toilet seems pretty stable. Especially now it’s been siliconed around the edges - though I’m sure the silicon doesn’t add any strength at all. While he was with us, Chris also fitted the small hand basin in our ensuite, tiled and grouted the splashbacks, then fitted a lot of sound insulation into the stud work between the three bathrooms (they all back on to each other, so good acoustic insulation is a definite plus!). He also bailed us out of a looming problem with our porcelain tile skirting… Tiling We were getting increasingly concerned whether our floor tiler would finish off the porcelain skirting tiles before we moved in. The quality of his work has been great, but since Christmas it’s been hard to schedule any time from him partly because he’s been ill and also he’s got a lot of other work, I guess. So we agreed to part company amicably, we agreed a payment for his completed the work, and my brother Chris stepped into the breach. Chris then spent a long day finishing off the skirtings, which really meant doing all the tricky mitre corners which had been left until last plus a few straight runs. For a simple, relatively open-plan house we had a surprising number of corners! Chris then went round and grouted 130 m of skirting. Great job Bro! We decided to hire a recommended specialist silicon guy to apply silicon around the bottom and the top of the skirtings, 260m in total. He did a great job, and very quickly. He is certainly getting a good rate for it! But I’d agreed a fixed rate and he did it to a good standard so, fair enough… Specialist siliconing is obviously where the money is these days! Anyway, all our tiling and skirtings grouting and siliconing is now officially… done! Kitchen Chris the carpenter has finished off all the outstanding jobs in the kitchen, including the final fit of ‘wall of ovens’ in the alcove where they sit. I’d been pondering the best approach to ventilation and with Chris’s help we came up with a what I think is a neat solution - creating a slender recessed ventilation strip above the ovens which is there but doesn’t catch the eye. Chris also fitted the plinths which make the kitchen look finished rather than work-in-progress. The Quooker tap is now powered up in as well as plumbed in and we have been using it for the first time over the past couple of days. I have to say I’m really impressed; it works really well and feels and looks great too. Electrics Progress on second fit electrics has been frustrating, I think mainly because our electricians have got too much work on and they’re trying to juggle multiple jobs. Also to be fair, our installation has been more complex than originally envisaged due to choices we’ve made. The rate of progress hasn’t been a problem until recently but it’s begun to feel like we might not have the electrics ready to move in: However, our main man Darren was in this week and made good progress, and we now have power and lighting throughout the house. All the kitchen equipment is powered up and whilst there could still be a fair few jobs outstanding after we move in (e.g. external lights) it’s clear that the electrics are going to be working well enough for us to move in as planned on the 23rd. Yesterday Nick, the electric contractors boss, demonstrated the seamless switch-over from mains to battery by switching off the mains supply without causing so much as a flicker to the lights. I wanted to try it myself when we had friends round later but Mrs P wouldn’t let me: “it’s not a toy” apparently. I was wondering whether we would actually know if we had a power cut, but the battery app sends us a message to say the power’s tripped over to batteries and then another one when the power is restored and it’s tripped back. I was a bit worried that, with the electrical work ‘growing’ and there being a fair few extras that we’ve asked for, the final bill was going to be way over the original quote. So I have been badgering Nick to give us a revised quote. He has finally done that, and yes, it’s going to cost us a bit more than he first quoted but actually not nearly as much more as I feared. Which is a result! Joinery Meanwhile on the joinery front, the oak we ordered to use as full width door jambs and the pocket door frame sections have all arrived. Mrs. P. has Osmo oiled them, fitting has started and they should all be installed by the time we move in. Rear landscaping Lots of activity is now underway on our rear landscaping. We have a fall of about 1.5 metres from the house finished floor level to the far end of the “residential garden“ part of our land. As I am a wheelchair user we are naturally wanting to have step free access to as much of that as possible. The garden design we have involves level access from the house to a terrace seating area, then 1:20 ramps down to three different further small seating areas between planting areas. That obviously involves quite a lot of low retaining walls and ramped paths. So given we are in the middle of the winter monsoon season, it was clearly an ideal time to start work on those walls, paths and terraces! Ashley and his team have made great progress despite the weather, as you can see - although if their landscaping work ever dries up (ha ha!) they could probably get good employment as World War 1 battle scene recreators. Front landscaping If the back garden looks like the Somme, in front of the house the parking/turning area is looking much more civilised. We debated about how to finish the surface, considering a number of options, but in the end we’ve gone for simple tarmac. Gravel is a no-no for the wheelchair, resin bonded is too expensive, brick pavers we don’t like the look of and need regular cleaning. In a previous house we had hot-rolled grit into tarmac and that does look nice but we found it collects dirt and is a recipe for bringing grit into the house, so we’re keeping it simple this time. The base coat is down and the front apron is being done tomorrow(!). The aim is to leave the top coat until all the heavy work in the back is done, to avoid damaging it. Ashley has told us several times we’re doing it the wrong way round - we should have started at the back and worked forward - but having that base coat down is transformational for me - no more wheeling through lumps of clay or getting bogged down in loose type 1. Preparation under way: Troy anointing the prepared sub-base. "May God bless her and all who walk/wheel on her": Laying down the blacktop: First flower bed planted! Focus for the next two weeks: Moving in! Dashboard: Contractor days on site this past two weeks: 45 Contractor days on site since build start: 572 Budget: No change - over budget but within contingency. Plan: Moving in on 23rd February. Issues and worries closed this fortnight: Hanging that toilet Whether the electrics would be ready Finishing the skirtings Current top issues and worries: Packing! (I expect Mrs P. has it all under control ;-))

Weeks 56 to 74 The UFH is laid and the screed is providing a lovely wobble free surface for the ladders and makes brushing up so much nicer. Our neighbour kindly lent us his scaffold tower so that we could insulate the vaulted ceiling in the open plan area which is approx 5m high. This has enabled me to finish insulating between the rafters with 140mm of Rockwool and I have PIR sheets to put up under the rafters. For cutting both the Rockwool and the PIR I created a few templates of different angles and had them ready for when my husband came to help pass them up to me. Once the Rockwool was finished we both took it in turns on the scaffold tower fitting the PIR. Having a vaulted ceiling in the openplan area and partially vaulted elsewhere will give us plenty of light and nice high ceilings but for now they are awkward to cut around to insulate and ensure the VCL is tight around the junctions. The time spent doing this will no doubt be forgotten once we move in and it is starting to feel closer. We marked out the kitchen island location and dining room table location to get first fix electic lighting located and measured for the kitchen units. For my birthday treat our daughter came to stay and dog sit our elderly Greyhound so that we could go shopping looking at kitchens. We spent almost 4 hours in Wren Exeter with Harvinder but we think we have ordered a lovely kitchen and pantry. Unfortunately our neighbour needed the scaffold tower back but said we could borrow it again as soon as he had finished with it. We then decided we should book in the plasterer as things were starting to come together, rather luckily for us our plasterer had just had a job cancel on him and when we spoke to him on a Thursday he said he could start next week either Tuesday or Wednesday. As we hadn’t finished insulating one side of the vaulted ceiling we said we couldn’t be ready that quick unless he wanted to quote for fitting the PIR and the VCL, which I had already purchased most of. We then spent the weekend and Monday getting first fix electrics in the kitchen and mocking up where the TV was going to get the electrics and room wall lighting ready. Things have therefore started to move on quicker than we expected, so we are hopeful of moving in by winter this year with a working kitchen, one bathroom and one bedroom finished at least. Kitchen design render. Testing TV and speaker location. Even with the plasterboard lifter its hard with 3 on the scaff and one on the lifter, so glad I'm not doing it. Taking time off the insulation has meant I can tidy the UFH expansion foam up in all the rooms and the trip hazards we kept ignoring at door room openings, whilst being on hand for the plasterers if they need more tape etc or have any questions. Once they have finished with the VCL membrane I might finish the VCL I started before we borrowed the scaffold tower or I could take a rest from the build and catch up on so many other things, even paint schemes maybe. I have caught up on the build paperwork this weekend. The total spend to date including the provisional kitchen figure of £15,000 which includes VAT, units, worktop, tiles and some appliances so not the reclaim amount. Total to date £238917 over 135m2 is £1770 m2 for a 3 bed, 2 bath, bungalow This is broken down as follows. General £4200 Carpentry £500 Kitchen £15100 Roof insulation, inc membrane and tapes etc £4500 First Fix Electrical £1230 First fix plumbing and partial bathroom costs (ongoing) £1430 UFH £900 Drainage and gutering £8540 Floor insulation inc tape and membranes £2670 Screed £2740 Cladding (over ordered but ideas are developing) £5690 Render £3090 Solar 7.5 KWp £8570 Roof £23300 Windows £20870 no front door yet. ICF Construction £119600 Pre build costs and fees etc £15830 The back of envelope guesstimate of future spend is £35k to finish apx £2k per m2

Been a bit bored as I have not been able to concentrate on anything much recently, but life is getting back to normal. I read on here a lot about the advantages of insulation, airtightness, MVHR etc, but this misses a few points. Form is one of them, a simple cube is a pretty good shape for thermal efficiency, and the bigger it is, the better it looks. So I thought I would knock up a very basic spreadsheet that can be used to explore the differences between size, form, thermal properties (just U-Value), air changes an hour for a cuboid. This is basically to just show the ratios and theoretical power transfers. Cells B3 to B11 can be changed with the snapshot results shown in cells B13 to B17. Below that are some data arrays that show ventilation and fabric losses, and ratios for surface area to volume and fabric to ventillation for different form factors for the cuboids. Not sure how useful this will be to anyone, but it does put numbers to changes i.e. you can change the ACH and U-Value and see which will have the greater effect. This is a very limited scope spreadsheet, so a lot of interpretation is needed. It does produce some charts though. Compare U-Values and ACH.ods

Week 36 When I posted the previous blog two weeks ago we were looking ahead to activity on the bathrooms and electrics, and also to making a start on the landscaping. Since then it’s been a fortnight of progress and challenges… Bathrooms My brother Chris made brilliant progress throughout the week he was with us. A toilet, basin and shower screen were fitted to finish the guest ensuite, a basin and shower screen fitted in the family bathroom to finish that room, and the bath, hand shower and basin were fitted in the master ensuite. It was all going really well. Too well. And sure enough disaster struck while fitting the wall-hung shower toilet in the master en-suite. We* were gently tightening the bolts that hold the toilet to the frame when there was a ‘ping’, then a crack appeared around one bolt boss, before replicating itself on the other boss, and then the whole pan came away from the frame in a Rapid Unscheduled Disassembly. Which was a bit disappointing, to say the least. (*Yes, I was 'helping' - that could be the true root-cause of the problem to be fair.) That white rectangle on the wall is a foam pad which is meant to cushion the pan against the wall to be trimmed away after fitting. We obviously never got that far. The actual cause proved to be a mismatch between the TECE wall frame instructions and those supplied with the GSI Ceramica WClean toilet. We followed both sets of instructions as closely as you ever can follow these modern 'pictogram', wordless instructions. Sadly, this led to the pan being inadequately supported directly behind the bolt bosses and the pan shattered as the bolts were tightened and the stresses rose in the ceramic. Here's the template the TECE frame instructions encourage you to cut out around. Which leaves you with an unfortunate void around the bolt holes. Of course, as soon as it happened we both kicked ourselves for not spotting the problem beforehand. At that point, I wished I had bought a Geberit frame and toilet as I originally intended rather than being persuaded by the bathroom showroom that these were better products. In fairness to the showroom (Island Bathrooms in Salisbury) they immediately agreed to supply a replacement pan, which arrived this week and we will have another attempt to fit it when my brother is back with us next week - first making sure that those bolt bosses are fully supported! Fingers-crossed! Notwithstanding that disappointment, as well as all the great bathroom progress Chris found time get the kitchen sink and Quooker tap, and the utility sink all plumbed in too! Landscaping Ashley Ralph, our landscaper, made a start on our external landscaping during the wettest January for years! (We had 259mm - over 10” - of rain in the month in our corner of Dorset.) Having temporarily turned our relatively tidy site into a recreation of the Battle of the Somme, he has quickly got a good covering of type 1 packed down and the site looks relatively tidy again. In fact tidier than it did before. To be fair, Ashley does keep things very tidy. Concrete pad for a future potential car port. The plan is to tarmac most of the front to make vehicle and wheelchair access nice and easy. We did consider a layer of hot-rolled grit over the top, which we did in our previous house and which looks attractive but when it’s not being walked into the house the grit collects dirt over time and becomes impossible to keep clean. So tarmac it is. Behind the house is more complicated with a fall of 1.6m over 17m of garden. To make that as wheelchair accessible as possible we have an intricate plan of terraces, ramps, dwarf retaining walls and planting beds which we’re hoping Ashley can install in our relatively compact garden. This mini-project could be running for some time! Cladding Alan, chippie No. 1, came in for a week and all the timber wall cladding is now done! All that remains now on the cladding front is for some of the soffits including those under the front and rear roof canopies, to be clad. The chippies may need to perfect the art of hovering above in-progress landscape works while they do that (!) Electrics Electricians seem to have become a bit scarce, which is a worry. To be fair we had two in the week before last, and a lot of lights were connected up but no significant milestones seem to have been reached. We still have a lot to get through to have a fully wired house before we move in on the 23rd February. And no electricians are planned on site until 9th Feb, so this is becoming a concern. Tiling We’ve also struggled to get our tiler in to finish off the porcelain skirtings - a couple of planned visits cancelled due to illness. Whilst we could move in with the skirtings as they are now it is obviously preferable not to be trying to finish them off with our furniture in the room. A ‘plan B’ is emerging to allow us to get this one over the line without relying on our principal tiler, who although good does not appear to be in great health right now. Internal joinery We have some further oak sections on order to give us enough material to finish the pocket door frames in oak rather than the primed MDF Eclisse supplied. Also since we have decided to opt for full width door stops to give a rebated door frame look, we are waiting for those to arrive so that they can be fitted. The oak door frames and architraves really do set the doors off well - we’re very pleased with them. Focus for the next three weeks: Electrics, still lots to do. Plumbing - that wall hung toilet! Landscaping - onwards and downwards. Packing - it has to be done , because… … we’re going to be moving in in three week’s time! Dashboard: Contractor days on site this past two weeks: 32 Contractor days on site since build start: 527 Budget: No change - over budget but within contingency. Plan: Moving in booked for 23rd February. Issues and worries closed this fortnight: N/A Current top issues and worries: Whether the electrics will be done in tome for our move. Hanging that toilet.

Last night was my first night sleeping in my new house, finally! Got 1 bedroom mostly finished. Ikea wardrobes, painted, blind and floor installed. Just enough to call it a home! Lots more to do but it saves rent and commuting time. I plan to take it easy for the next fortnight as the last two years have been creeping up on me. Small projects for the short term. Getting internal doors installed (by someone else!) currently. Put some acoustic insulation around the linings and cut it back. I like the look of the wood/oak veneer. Been chasing documentation for the BER (SAP) assessor. It adds up to quite a lot. Doors, Windows, Heating systems, section plans, U value calcs. Think I have all of it now - hopefully they'll issue a BER Cert soon! My airtightness commission went sideways, lots of leaks. So one of my snags is to put air tightness tape around all the ducts to the MVHR unit and outdoors and also between it and the manifolds. The testing unit is very sensitive (even dropping it puts it out of commission for two weeks!) so I've a bit of work to do before I call them back. The Renson Endura Delta 330 has a few levels of ventilation and they upped the minimums from 50m3/hr to 127. Will see with single occupancy if I adjust this down a bit. I can monitor the unit with an app only, there's no display. I noticed when I ran the supersayer gas heater for a few hours to warm the house (as the gas bottles had been unused for the last two years) the CO2 levels hit the roof and it went to max flow rate to clear it out. Anyway, I plan to use the Air to air system more going forward and that won't cause the same issue. Had two floods to deal with. I've a japanese bath I was trying out. We'd filled the bath with a little water to check for leaks a few weeks ago and it drained fine. The bath is on a platform to allow for a trap to be installed below it. The drain for the bath just fits into a grill so it's open and can potentially overflow which is what happened after I fully filled it, used it and two days later pulled the plug! Luckily I put the plug back in and used towels to keep the water in the bathroom as it's tanked / is a wetroom so no damage was caused to the rest of the house. There is a seat in the bath so I was trying to get the most comfortable position and removed the seat. I'll probably put it back as it's a short bath and my back didn't like the sitting position on the floor of that bath all scrunched up. The seat means you only get heat around your hips so will have to have a think about it more at some stage. Or get a bigger bath! The second incident was with the washing machine last night. The discharge pipe isn't big enough for the tumble dryer, air to air condensate and the washing machine so I got an adapter that taps into the side of the pipe with a spigot for the washing machine discharge. This didn't seal/hold so it spilled everywhere. I think I'll go back to basics, replace that section of pipe and glue on a y bend to create two parallel discharge pipes and this way I can get everything connected at once and no risk of floods! My car charger won't reach the car as it's about a meter short but that's due to a big hole I've to backfill with MOT. The dust is everywhere but at least with the internal doors I can mitigate this a bit going forward! So not finished yet but I have a doorbell, hot water, heating and an amazing house to walk around in and rest a bit before finishing the final list of projects and call it a day!
