Won't work on concrete though. I've done floating timber with glued joints before now.

I think timber frame and block cavity are easy with finance. You'd have to check with CML or uk finance whatever they're called now make sure the majority of lenders are happy

Not as good for finance or future sales purposes I think?

You can still full fill up there then? I thought it went on exposure zones? The stuff is deffo water repellent. An offcut can sit in a puddle for a week and is no heavier for it.

Ive had pumped before and slabs. Id be interested as to what is better around cavity trays. Do pumped beads or dritherm work their way around all the folds and lintels? Pumped used to be cheaper at one point but then slabs became cheaper again. I find its easier to keep cavity clean of mortar with slabs. The compo just drops down onto last row of bats and clean it off. When you have an open cavity it drops right down to the bottom.

@Gus Potter i think there are a lot of items in your list that get copied and pasted between jobs with tweaks. For instance design and access. Moving forward maybe AI will also cut the labour involved in design and access down too? I've never used an engineer to set out or survey and have built a few houses now, just use the OS maps. Even though I've never been quoted fees as a % it is relevant because in your example 9k on a half a million pound house is a lot different to half a million on a 2 million quid house. The uplift in plot value on the planning permission will be a lot more.

Insured tree man. Like you say too built up around there. Ideally one with a stump grinder as well. Done and dusted in 1 day then.

Didnt @tonyshouse try this with a borehole in his basement. Probably too late to do now as it heated the ground up under his house iirc

Is there a photo?

Tbf im not really on about re building our network based on coal or running off 100% coal. All I'm saying is its been a choice to demolish our remaining working coal power stations. Will that be a good choice time will tell. I don't think it is. A lot here seem to be doing some impressive mental gymnastics to explain why China are building lots of new coal plants but it's ok for them.

Before you pour is better, while the digger is still there.

Sorry my reply wasn't aimed at you it was to the people who were telling me coal isn't secure.

So coal has a place to help secure energy. Are we all paying attention now

Say 200mm stone, 200mm insulation, 100mm slab. 500mm. Less full being 150mm above ground gets you to 350 reduced dig off ground height. Can reduce insulation with pir and prob go down to 150mm with stone
