I've had a bucket under our mbhr for four years now. It only produces condensate when it's cold and dry outside. Dry most of the time. Maybe makes 10l in a year.

We fitted 100mm EPS on the outside to get our standard amvic blocks to 0.15. it's a LOT of work!!! But relatively easy. If you do PIR inside, you lose space and make fitting plasterboard more problematic - no guide lines for screws and screws will have to be something like 100mm+ We never did a service void, spark was happy to chase out with a hot wire cutter. Nothing else is really run in the external walls

Is agree. UFH all the way in 1st floor. We bought towel rads as well, still sitting in their boxes. As we had concrete and screed 1st floors, cost of UFH on 1st floor was minimal, 500m of pipe, pump and manifold. rads would have coated way more and compromised the rooms.

Yes, I would. A few long screws would do the job well. For the sake of £10 and less than an hour of work.

We've sockets with USB A and C ports in them through the entire house. It's wonderful, no longer need to faff around looking for a charger, or not having enough sockets. Ours are Click brand and we've not had a single failure 5 years in. The C ports are more powerful than the A ports and most of our plugin chargers.

Where is the water currently discharging to?

Worked on various projects in the middle east where TSE (treated sewage effulant) is used for municipal irrigation. It's common and perfectly safe for non-crop irrigation. But it all depends on your treatment system and what standard of effulant comes out. Storage, distribution and handling needs to be thought out and designed. To be honest, I'd just get a couple large rainwater storage tanks (e.g IBCs) instead. Two IBCs will irrigate a medium sized garden for a minimum 20 days with no top-up. Tanks, connectors, pump etc will come in at less than £300.

A few insights from my ICF build. The planks can only partially bear as you have vertical rebar coming up from the wall below that needs to tie into the next wall. You don't need to seal up the end of the slabs - a combination of the small diameter of the holes, interference from rebar, and by not working the concrete at that point (poker will vibrate the concrete at the bottom of the formwork), it simply won't flow in more than a short lenght if the consistency of the concrete is correct. You won't have an issue unless you are using an overly low slump / high flowing mix. Also, you normally need to bend over a certain number of the vertical bars and break into the planks. Then get grouted in, in order to tie the floor to the wall.

I'd just bring out a stud wall to the top step to ~1m height.

I used the HEP20 3/4 - 15mm push fit directly into my cross water mixer. A bit of PTFE on the threads. No issues 5 years in.

Ours were all screwed directly to the icf (amvic). Just need to chase out the cable runs in advance with a hot wire cutter. Battening out is not required, more money, time, no performance gain, and less space in your rooms.

Phone Scottish water and they will send somebody out to sort it.

Waterproof PVA 🤣 A smear of silicone Lick of varnish Used all three from time to time and all good options. Waterproof PVA would be my choice if it's MDF, silicone if it's chipboard.

I made sure the washout area was a spot that would be later paved / concreted over. Each time there was a dump of concrete or cement, I'd rake it out flat and level. Ended up covering a good 20m²+ and 100mm+ thick by the time we were done. Concrete pumps produce a lot of waste!

Don't do any filling now, give it a year to let any drying/ movement/expansion/contraction finish off. And when you do, rake out any narrow cracks with edge of a paint scraper before filling.

Maybe. Pro: longer PRV life Con: likely to get clogged and reduce flow over time. Regular cleaning needed. In water networks, strainers cause more issues and cost than they save. Primarily because once they are fitted, they are forgotten about. Hidden. Don't provide a day to day function, and no telemetry giving any idea of condition or functional performance. If you do fit one, set a reminder on your calender to clean it every 6 months.

1.8m from local ground level. no limits on hedges.... Get some 6ft Griselda/laurel/box for fast growing screening. Wouldn't plant this time of year tho, we're struggling to keep our new beech hedge alive in this weather

Key thing is the steel to concrete ratio along with spacing between the mesh. See if you can use this to do a quick check. https://wutools.com/calc/engineering/rebar-calculator

Welcome. First thing will be to get a drawing from Severn Trent showing the location and details of the sewer. If there are any discrepancies, request they come out and survey it to confirm. Check your property deeds for a way leave. There may not be one depending on the age of the sewer Whether you get permission to build over or not, that's a complete lottery I'm afraid. same for planning. Precedence a couple miles away doesn't really apply, it's what's been done on your street. Best of luck. Ask as many questions here as you like.

No need to fix down once you get worktops on and fill the cupboards.

Is it just a vent pipe or is it a function stack? If it's just for venting, bury over it, fit another one somewhere else, or use a combo of air admittance cables instead.

200mm is a bit out of what you could call a margin of error. we did similar, ended up 250mm too high by the time we got up to the ridge. I made the call to drop the wall plate by 100mm and the ridge by 150mm. So we edend up about 100mm too tall. Could not got away with any more as we set the ridge height to be mid way between the houses either side of us. It depends on your design and construction method, but trimming 100mm off your ridge and wall plate might help you sleep at night. we were building ICF and a panel roof system, sownqs dead easy to make the change.

Internal on painted steels. Not a clue where I got it from, was five years ago.

I used foil faced aerogel, easier to work with and stick down. I think I used double sided tape.

We (un)subtlety told the surveyor the valuation we needed. He did this on all bar one occasion.
