Why would they do it like this just sounds like aggro. I can understand the other way round waiting till roof is on and pour a slab/screed that is pretty common

I think it's all cyclical. We've been so long in the time when land prices are so high. I remember early 2010 you could haggle for prices with plots on open market and there was a lot of meat left on the bone for whoever built it out. Nowadays builders seem to be almost buying the work with the plots for sale on the open market. All that risk and capital tied up for 20 maybe 25% with all the time it takes and regulations to comply with. God forbid there was ever an accident with all this principle contractor and designer nonsense. I'm sure it will go back the other way at some point.

Channel it with a saw and breaker it out or deeper than 6" from top?

Joe90 had a simple wide cavity with solid eps fill. Off the denby wood design or whatever it was called

Yeh wasn't it terrye that rings a bell

Oh well you can't bring another up now but one near opposite corner or in stud / plant room behind would of been helpful. I think you are limited to how close connections can be on the horizontal level. Ie a branch connection has to be so far below a toilet waste. Check out the build regs doc it has these dimensions in

Do you also have to consider what your cladding the frame with? Lightweight works well with raft, brick or block can be a bit trickier. Didn't someone here have a bit of bother with this and cold bridging years ago?

Why is you waste pipe miles away from where it's needed? I'm not sure you can have 2 appliances into a single 40ish mm pipe? Building regs doc is pretty helpful. Check that out.

No. Sometimes I rethink on self build. For the price you pay for an older property, I think especially with some of the nicer period ones, you literally couldn't rebuild them for the price you can buy them for. The skills are not there. That's before you consider the quality of the materials used compared to now. Obviously there's cons to an older house but I'm not sure energy efficiency is the be all and end all it's made out to be.

I think even the quality of clay is not as good as it used to be. I've chopped into old clay before to make connections good as gold tried it couple of years ago on some modern clay stuff, supersleeve? It just went dead brittle and splintered into a million pieces. You can probably find some better quality stuff though. Was on a job where a 6" public drain had to be diverted and that was all in clay so must be a reason the water companies prefer it.

I set ours too high in last place. Got used to it but would've been better lower. Can't remember the best angles for watching but available online.

I think deciding on shower tray is a pretty crucial decision very early in the process. My last place was a bungalow and I decided, and maybe bought it before even coming up out of the ground. Got the 110 waste pipe bang on centre of the shower waste I'm sure there are enough different layouts of tray to get you out of trouble on a first floor but for gf showers in solid floor it's especially important.

Thanks for detailed reply. Looks like heat pump is the winner for new build if you are on the right tariff. I will consider for my next place. Maybe bottled gas is the way forward for cooking. In those articles are they saying that the price difference between gas and leccy is growing? To me it seems like the more renewables they turn on the higher energy prices go. Subsidies and linking the price to gas is killing us on these. I remember years ago jeremy saying how the gas price was only going to increase relative to leccy. My argument was if it went too high the govt would end up subsidising it. When the Ukraine business happened and energy shot up this is exactly what happened. It's stupid because we're only subsidising our energy bills with debt or future taxes but that's how daft politics can be.

I just came across a post on x and it had both these articles linked

While browsing online this afternoon I see this crop up. Apparently govt chef scientist says heat pumps won't save money. I'm sure there are nuances and I know that the high performance houses being built by members on this forum would be more suitable than others. How does this link square with what was being said here @JohnMo? Are they referring to cop with the figure of 2.8? Are they saying that it would have to be 4 to match gas? Excuse my ignorance I've never never ran a hp before. https://thegwpf.org/publications/new-paper-reveals-governments-heat-pump-plan-as-uneconomic/ https://www.telegraph.co.uk/money/net-zero/not-clear-heat-pumps-save-people-money/
