This although we have two UV sterilisers, the treatment plant compressor does switch off and on, borehole pump although that probably only runs once a day, control panel for that, our water is pumped into the house. Other half wfh so there’s three screens, and a laptop. I also have a bunch of networking stuff and Starlink consumes a bit. We’re np about 450W background load. It was higher but have put everything on standby when idling or off overnight.

Ours is about the same.

Agree with @JohnMo We run the house at a lower temperature on no schedules but it stays at that temperature pretty much rather than heating up and cooling down which you will feel more than a more constant but slightly lower temperature.

Cold here yesterday (below freezing all day) Heat pump consumed 11kWh of electricity but we have the temps set at 19.5°C. Very bright though so a bit of solar gain.

Jeez that’s bad. The detailing on ours isn’t the neatest but I’m reasonably confident in its robustness. I did also have to have the trims redone. There was gap between the flat roof getting started and finished. The stuff won’t weld if it gets dirty so has to be thoroughly cleaned with a specific product which they never did so the welds all failed. The manufacturer signs the work off and he wasn’t happy with it. I did fall out with the company we used for various reasons. I’ve looked at a few flat roofs using single ply and they are all a bit crap in the detailing. I have subsequently been up on another flat roof which was done well with very neat corners so I know it can be done well rather than it’s just the nature of this stuff.

There’s been examples of the BCO dropping by on here before now. Mine did once just because he was passing the house. I have experience of one house build and one BCO and he was excellent, very helpful and pragmatic and saved me money. I did everything by the book though.

Same score as us. I would have thought curiosity, if nothing else, would encourage you to get the air tightness test result. Bit late to do anything about it now of course if it’s crap other than switch off the MVHR. Like @JohnMosays it’s been a requirement in Scotland for final sign off for some time. You are right about you being the only person interested in it. The next buyer likely won’t be unless the cost of electricity gets high enough that low running cost houses attract a premium. Even my other half wasn’t that interested other than what was required to get the final sign off.

Ours is a little like a Larsen truss. Full fill and deep walls.

If I as building again I’d quite likely go ICF I think.

I’ve been in a few SIPs built houses (all Heb Homes) and also noticed they weren’t very sound proof from outside noises. I’d already decided not to use SIPs for other reasons but it added to my list of why I wouldn’t use it. The space frame we built is very quiet however it does suffer a bit from vibration but only at the French doors in that if they are shut quite hard you can feel the vibration very slightly upstairs.

You want BC in your side not pissing them off before you’ve got started so I’m with the above. It doesn’t stop folk from doing it of course. Some get away with it some don’t.

It’s better to reduce the extent of the glazing. However we bought the plot for the view and full height windows are nice feature in my opinion. Most of our south elevation is glass so the temperature in those rooms varies a lot more and more quickly. The temperature in the other rooms tends to be a lot more stable and consistent. As always it’s a compromise.

I used Raj Green sandstone wall cladding. Comes in sheets and only 11mm thick so quite neat. Matches the slabs perfectly. I had intended to use cut slabs but they are nominally 22mm +- a bit so too thick.

Good. 😂 As it turns out my insistence on doing it the way I wanted was the right decision too.

You’d think. Except that wasn’t my experience. On window installation day there was a lot of head scratching and disagreement on how to do it. The installation team wanted to do it one way, the joiner I had on-site said he wouldn’t do it that way, the generic construction drawings said something else that didn’t quite reflect our build. In the end we did it the way I decided to do it based on what I’d read on here. I think the only way to achieve consistency of build using generic construction drawings is to also mandate what is built other than size and shape assuming simple shapes. We went kit build for speed and reduced risk and we enjoyed neither benefit as it turned out. But we were probably just a bit unlucky with the choice of kit supplier.
