when you say buffer do you mean a tank/cylinder ?

cant. still want hot water but also cold air hence 2 separate tanks.

for next time. 1 chamber

have a look at a normal brick/block build and incorporate some oak features into it. Will be less than half the price of any of the timber builds, look better and last longer.

add a few more and make a feature out of them like crazy pathing!

move your toilets to stud walls to avoid the unsightly boxing in, lose the pipework in the stud.

middle leg, set back.

you need a planning consultant to manage the application. They swim in the same circles. Architects are next to useless when it comes to planning, and pretty much everything else...

the GSE in roof trays are £65 Solar panels say £160 plus inverter and cables. not a bad price id say. They making £1500-2000 for a days work.

pointless.

will need to have a very skinny handle and a forgiving BCO to pass that.

tru stud. Think of your carbon footprint using metal.

your not measuring it right. from the outside of the handle parallel to the wall into which the window is fitted. Not at that angle. Doesn't look wide enough, had to use a flying mulion on one of ours (1100 width).

amazed BCO signed off that. Shocking really.

couldnt you lose one of the chambers that are very close together ? a 300 can go 600ish deep, you are very close to surface by looks.

those are not fire hinges. just buy a set and the window will fully open.

why such big chambers ? They are bloody expensive!

where the DPC, the builders forgot it ?

not that great, corridors, no lounge, expensive flat roof box tacked on back. Are you planning to spend £4-5k m2 to build it as that is an expensive build. it hasnt got anything with a wow factor.

sikkens cetol is really good. not cheap.

tesla.

thinking more on the cooling setup. Would a dedicated 'cooling' cylinder make sense ? In our setup we have 120m2 of ufh pipes to cool then 7 fancoils which adds up to a lot of piping. would it be more efficient for the ASHP to cool down a dedicated cylinder then spin this cooled water through the fancoils/ufh via the cylinder heat exchanger?

7038 looks really good, hard to tell from a computer screen as they show colours differently.

shockingly bad design. open everything is the work of the devil like purple bathroom suites from the 70's

be careful of using a 'hybrid' method with insulation below. very much harder so seal the roof structure to make it airtight.
