who would have though rubber was stretchy. lol

its virtually guaranteed grp will movement fail before EDPM. EDPM also greener being a recycled product.

EDPM superior in every way including fitting, the warmer it is the softer the rubber!

all i will say is they get soggy as buggery when it rains... They are still the least worst option though.

interesting. is there really that much load though ? Looks like maybe a pack of bricks above the cutout, same in blocks on inside. A share of the roof as well. The corner is still there taking most of the load and assume the floor joists are still sharing the load with the other wall. Fair enough they should have dropped a scaff plank or 2 under the acro's. Doesnt look that bad though ?

i wouldnt. kitchen down first then run flooring into the legs, covered by plinth. guarantee you have no issues with movement then.

go for 300mm EPS. cheap and good bang for the buck. You have the room already. simplify your buildup. trench block + concrete common then beam on top.

just looks crap. built into a stud wall is soo much cleaner.

very very bad year for pollen, my eldest is really struggling. the hepa+uv filter on the mvhr will be a godsend.

the slab wont be level enough to lay flooring on. Dig it down more and the problem is solved.

take it on the chin. some flooring is worse than others for expansion. You supplied it so ball stops with you really. Not a massive job, remove skirting, trim it back and put new skirting on - repaint. Get some karndean next time!!

just be careful scaling off printed plans. not all printers print to scale. This can work in your favour should enforcement come knocking, a pencil line on some drawings is 100mm on the ground......

not necessarily. Depending on your ground type building control can cover upto 2.5M depth. £25k is daylight robbery. Have them do plans and elevations to your liking then sack them off. If you have the time and inclination all the rest you can sort.

just to derail your thread, the mrs wanted bars on the new windows but they cannot pass new regs with them. ruins the U value apparently....

correct. unless HMRC now have below ground footings inspectors with X-ray vision.

shame the correct flooring detail below FFL is often overlooked. see a lot of threads here with same. A simple thing to get right at the time, very hard after. Yet another basic building function architects are clueless on.

i use these guys, they do a water and tear proof paper. https://www.ezeeplan.co.uk/

you have cold bridging there. we are delinking the footings with Marmox block here to avoid it. bloody expensive too

150 batt 150 cav etc.

interesting, how did that work stopping the cold bridge to footings ? Having to use marnox blocks to achieve this on ours and they are horrendously expensive....

maybe there is a double ashp so in cooling mode it can shed the heat into the other pump to blast the dhw.

have 9.9kw solar, this time of year the heat pump will be in cooling mode though so not available for dhw.

they dont need it, limitless virtually free natural gas (waste product of their massive oil reserves).

dont confuse the two issues, green is bs politics. Insulating homes is common sense.

would have extended the cill to the wall rather than leave a little gap. Doesnt look that bad in fairness, decent decorator will polish it up.
