Don't tell your wife I said this, but you need to go grab the credit card for next years holidays, and to shoot down the big boys tool shop with it, and get fully kitted out asap lol. If there's one hole in your new oversized tool belt that is empty, you're in deep trouble It's easier to ask for forgiveness than get permission !

Guess who you're ringing tomorrow for a chat about this installation!!

If they use a 600mm bucket then there's an opportunity to comply with their requirements for 'segregation', however I am still bemused as what exactly the conflict could be between the water and the electricity supplies..... Electricity and gas, maybe more relevant, but what the heck!? This is when installing ducts becomes your friend You simply pull the services through after the foundation has been installed. I'm curious as to what advice you've taken (or been given) regarding foundation type? Have you done geotechnical surveys yet? From what you are typing, I am a bit worried that you don't have a very tight grasp on what's what here. Not a problem, because you are now a member here and we will 'learn you good'.

What make are the units?

You can get 1L tins iirc.

Prob better to use the £100 for beer as nobody can get the application approved. The architect should be advising as part of their ‘professional advice’.

Same if the existing boards are ok. Maybe use the opportunity to put some fresh acoustic insulation in there. For my SiL’s house I put plywood inside the metal webs of the MF tracks to beef up the walls before plaster boarding. Made the wall much stronger.

Cut along the red line, to leave the chipboard under the stud wall. Then put a piece of wood (18mm plywood or similar) under that existing flooring, wide enough to be 75mm under existing and 75mm on show, and screw / glue it by fixing down through the chipboard into the plywood to form a connecting ‘tongue’ of plywood. Then your new flooring will sit on that, which you then glue and screw down into, and job done.

erm....the other £70bn is engineered and just finds it's way out of the public purse and into the hands of c****. Same thing, year in year out. That's why in the UK we're switching off streetlights to try and save money. #utterlyfeckedandnothingwecandoaboutit

I was happy to install YY, until the merchant said they just don't sell any of it! 3-core flex it is. I just observe segregation where things like long LED strips are in the mix, so the DC runs are not bunched with equally long runs of AC stuff; unless it's a small bit of LED which doesn't really seem to ever care how you run the cable.......no complaints yet, so I'll belay starting to panic before bedtime. This. Under-volt = over-current, and then the LED's are on a shorter lifespan. RIP.

That's SELV, Safety Extra Low Voltage, old boy What someone says when a random Welshman on the 'interweb points out that they've spelt SELV incorrectly 🤦‍♂️😆

That projects out almost as much as the previous detail though? Very little in it, from what my Pentium 1 brain is looking at. Ultimately you will get a solution to the remit you have provided, so if you have specifically asked for the least projection solution possible then the AT needs to sharpen his pencil; however if you just said "give me a secret gutter" and no further information re particulars of how you want this to be presented have been forthcoming, then you must be willing to accept a draft revision (for discussion) at the outset so you can see what you 'don't like' and then request changes to arrive at something more inline with your expectations. This is self-build and feck all goes right first time plus...we're only human too. The issue I constantly struggle with is getting exacting information from my clients, but it's not because they don't know what they want, it's more about things getting lost in translation; folk simply don't know what the options and possibilities are, so they need to see something in front of them so they can say "close, but no cigar yet....let's discuss!". That's why I choose to work with a select few (patient and pragmatic) people, as they get the haywire between my ears. We arrive at solutions very quickly, with zero friction or fuss, and all whilst sharing the same common goal; get the client the best things we can for the least amount of time / money spent. Every damn day is a school day. I don't care who you are, how old, how experienced, if you can't be open to a bit of collaborative thinking and discussion (2 heads blah, blah, blah), and be patient whilst the answers begin to form into a thing or shape you like, then how would anyone ever get to the finish line with hair and sanity still intact? It's not a war, or a battle, it's a team effort; all you need are good team members to work with. So if the right solution doesn't jump off the 1st page of a thick book, best to not shit the bed methinks. Share your findings, google search images, likes and dislikes, and discuss! Then the juices will start flowing Then it'll be the best house it can ever be. Tres bien.

Erm, no? The red line is exaggerating the issue, and the only thing I would improve upon here is that the two insulation layers should meet, and not be separated by the flooring / deck boards as shown. The cold element of the steel is the edge of the upper 'toe' so is marginal at most (imho). Not if the airtightness is detailed correctly Attempting to use the PB layer as your AT layer is not a robust plan afaic, so maybe I have misunderstood you in that respect? The detail shown doesn't show an AVCL, so one can only assume you have not yet crossed that bridge with your AT and that's why it isn't detailed, yet?

Amen.
