I hope not, there comes a point where you need to define a detailed budget. I assume the biggie that could account for a + £700 sqm figure is an architect. Then add site insurance, mid build planning revision applications, pre build enviro surveys, ground quality test digs, crane hire, muck-a-away, planning consultants, 10 year warranty, mortgage arrangement fees, site fencing and building control. Someone recently said their m2 costs did not include main service connection charges which is highly dubious accounting. What about tools? I have probably spent over a £1000 on these, they will offer some post build benefit but it is money I would not have spent otherwise. There is a consensus that a detached garage build cost is excluded. When considering the broadest financial picture, each year in a static caravan saves £1000 on council tax, no need for gym membership and our holiday budget has shrunk. Long term I will be far less likely to get trades in to fix problems.

So true. There are lies, damn lies and square meter build costs.

You have broken Goggle Translate.

Just curious if the formula for how fitting PV improves the EPC score is in the public domain? Without PV I would expect to get a borderline C/B score. As discussed in another thread I could get 3 panels on my complex roof for an extra mid build cost of about £800. Getting the panels operational below the roof involves further cost.

About 800 to 1000 sq ft of internal floor space? I assume you have a plot ready to dig? If a natural slate roof fit a truss every 400mm and not the industry standard 600mm. Don't set out with an expectation you can achieve a final valuation that beats mainstream developers unless you plan to do loads of hands-on building. If you have nabbed yourself a highly desirable plot that helps but conversely a small personal new build comes with fixed costs unrelated to property size that a larger developer would spread across multiple properties. Try to include one small architectural indulgence to distinguish your finished property from what is built for the mass market. In your case I would specify special roof trusses that have the horizontal ceiling joist half way up the slope of the roof to create a sense of space in the open plan area. Or how about a feature oak beam to separate the kitchen from the main living space. Attic trusses for the rest of the roof will allow for more useful attic storage which could be more significant in a smaller property.

I had a long chat with planning, as I am lucky to live within a District Council that assigns a duty planner each day to handle random approaches from the public. They don't charge for extensive interactive chats that ramble on for 30 minutes. I learned the following: There is a general positive attitude to solar PV. If the solar PV is not visible from the road and front elevation they are unlike to object. Reflections off the glass panel surface that might dazzle and inconvenience others is a PV planning consideration. He was not familiar with the in-roof GSE system but understood the concept. A frameless in-roof system was clearly preferable to some plonk-on retrofit. All black panels did not excite the planner so much. And in my particular case: PV in the conservation area is ok subject to points above. I do not actually have a planning condition to fit slate, just a satisfied condition that a material sample of the roof be approved. An NMA is the safest planning option for me though he went off for a chat with a colleague to see if the PV could be nodded through as an updated roof sample material approval.

Ok thanks, so no thermal concerns about the smaller air gap when counter battens are not a component of a roof design?

Everything crosses my mind from rats chewing my mains water feed under ground to a tornado sucking up lead flashing from my roof.

@thorfun I might be doing the same GSE/natural slate install soon. Can I ask if your roof design with counter battens was chosen to increase the air gap under the panels? I am still a but nervous at the thought of exposing the underfelt to the heat under a PV panel with just a 25mm air gap.

Quite frankly your account reads to me as though your own duplicitous behaviour is coming back to haunt you. You initially volunteered support to your neighbour without any prompt and then continued to engage in a supportive dialogue with the neighbour and his architect contrary to your own true feelings and I think your interactions with the Council.

She might not get that. How about a fake planning notice announcing the build of a Bail Hostel for Teenage Pyromaniacs.

I think so but by accident rather than design. The Mr FixMyRoof of YouTube recommends adjusting the batten gauge to result in full sized slates right up to the ridge but with preholed slates and just 10 rows of full slates from eave to ridge it was not possible jiggle this outcome. So I ended up with 10 full slates rows plus an extra batten just 60mm further up close to the ridge. The 11th top row will need 2/3rd length slates so yes not far off an eave type row. To help you guys help me I will take a photo tomorrow and also upload a diagram. Thanks so far. I have run the felt from both sides right over the ridge and about 400mm down the other side so there is no concern about water ingress into the attic space. My concern about a reduction of head lap in the last top two rows that would make it too easy for water to get under the slates and then dribble down over the felt to the eave. I could widen the lead flashing ridge cap to achieve a full lap but that would look daft on a small roof.

Contentious self builds in established residential areas smoke out the crazys that's for sure.

My understanding is that a property owner can insist on a wayleave if access is required for installation.

It will be a more tidy long term solution for all concerned. Better start calling her the nice neighbour who helped push you towards a proper solution. In my case the disputed cable is still overhead but was routed down a public road from another pole. That span is 61m.

I am covering a roof with natural slate and I am one row below the ridge. The ridge capping will be lead flashing extending 150mm down over the top slate row each side of the ridge. The slates are 500mm long. Now that I have had a chance to visualise the final overlaps of top two rows of slates and the ridge lead capping, I don't think the end result will have the same amount of head lap as the main slate portion of the roof. My proposed solution is to fit a continuous linear soaker to the top batten (that is just below the ridge), before the top row of slates are nailed into position. My Question: Is there a material that is cheaper than code-3 lead that can be fitted directly under slate? This material will be in direct contact with the slates nailed on top and will have minimal sunlight exposure between a few 3mm gaps between slates. I was thinking of using some 200mm plastic dpc that is spare onsite but this might suffer on a hot day should the slate reach say 60 degrees (c). Another idea is to use regular breather membrane but that might abrade over the years as the slates expand on hot days or shuffled during high winds. There are plenty of non lead flashing substitutes on the market but these usually contain an aluminium mesh and I am concerned about galvanic action between this linear soaker and the proper external lead flashing capping the whole ridge. The ideal would be a heat tolerant roll of plastic no thicker than 3mm. As I type I am starting to think code-3 lead is the best option. A 180mm wide roll of lead is about £7 per linear meter.

You can if access to the property is required to install the new line. Two years ago when faced with a similar situation, though in that case I was playing the role of @pocster's neighbour, the forum was sympathetic to my plight and told me to dig my heels in and object to the oversailing intrusion. The fickle madness of crowds as they say. There are always two sides to such stories. In my case the pole was on the west boundary of my plot and the other property was 15m beyond the east boundary. The neighbour and BT OpenReach wanted to sling the cable 45m across the entire and longest dimension of my 45m x 30m plot. The total span was greater than BT's own 55m guidance. We had bought the plot specifically for the central courtyard feature and its southerly aspect. The proposed oversailing cable would have bisected that southerly view. Such oversailing cables can droop to 10ft before BT Openreach is obliged to take action.

Nope. In the case of a supply and fit contract there is a zero-rated VAT exemption if the contractor is convinced the property is a genuine ongoing new build. It must get difficult for contractors to assess this in the case of slow self builds where the owner moves into a part complete property.

I don't know, my two stoves will be situated in traditional fireplaces. Why don't you treat yourself to a short break in the Welsh Boarders then you could pop into Ludlow and subject the staff to your technical proficiency test. I don't know but when buying a manufactured item with an expected 20 to 40 year life span people tend use non technical assessments of a business because a human life is not long enough to run a sequence of 30 year product test experiments.

Leisure craft try to avoid tidal races but not commercial shipping. Tidal races typically occur off a headland and headlands are often the turning points for the shortest A to B route. When timed right a tidal race is the maritime equivalent of a jet airliner catching the jetstream for a fast transatlantic crossing. That rules out 99.9% of British sea area.

I get quarterly warnings of price increases from my main Builders Merchant, the latest just arrived. How long before the whole house building industry prices itself into an idle wait and see standoff? Only a gambler would start a self-build today but I suppose these new-build inflationary pressures drive up the price of existing houses a touch. This is what happens when big-state liberals think furlough & money printing is the best medicine to control a global pandemic!

My point is there is a fundamental and dangerous fallacy behind the claim "I am a smart dude and will recognise when my stove is malfunctioning before it gets dangerous". Air starved combustion leads to incomplete combustion and CO production. CO makes you non smart with little warning.

I have yet to install one but I can recommend a trip to their HQ in Ludlow where they have many working displays. The staff are very knowledgeable as well plus you get free parking in the centre of a tourist town.

Sure if it could be made to work. I wonder how they will keep the kites weed free. Marine growth starts to attach to a surface underwater within days of immersion unless the surface is painted with a toxic layer. I suppose they could anchor the kites in deeper water where there is less sunlight.

Where is the Yawn emoji? I assume you cannot offer a constructive response to the main question about a PV calculator that can offer a daily breakdown of capacity through the year?
