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.

there has to be a tray installed above lintels so water isnt an issue. You dont want to build in cold bridging where you dont have to, so the thermally broken is far superior.

warm roof better, harder to build correctly. Issues if not detailed correctly. Need more height 200mm Cold roof, easier to build, just leaks warm air if not done correctly, doesnt need extra height.

rest band as a 'foot' on it so you can concrete it upright.

avoid long corridors.

need to make sure you have the vertical tray installed first on the walls.

what we did on our 7m bifold, we hard a normal 170mm cill on it which provides the drip detail for the doors then slabbed over the cill with porcelain, we put pea gravel under the cill to support and provide drainage. No need for any linear drains and nothing to worry about with splashing etc. Had no problems with it at all, the frame free drains as it should.

and in the meantime another 20000000 plants are growing. google carbon neutral.

cosmetic. would have been built on no footings at all.
