How did you get away with less than the part F 4 ACH for the extract rooms?

Not sure I get this do you mean taking large bores off manifolds to higher manifolds is a problem and if so why are higher volumes more problematic is it to do with velocity in larger diameter ducts?

Welcome to THE forum for people like us. People on here are always up for moral, mental health, engineering & general building support. It is a struggle but you seem to have had more uphill at the start. If you have a clear site it must be a new build or have I missed something? Also warranties, ours is from buildStore, are really only any good for years 2-9 of the building exitance. This because the expectation of self builders is that they live in the building for at least a year so fix any issues and then the warranties kick in for 3rd parties who might purchase the property. However if it is your forever home then you won't be selling so the whole thig becomes a little less important. At the outermost level both your structural engineer and architect must carry Professional Indemnity Insurance (PI) and so in the case of major failure of one sort or another you may be able to claim on that - indeed your average warranty company will often look in that direction if things go wrong that are so attributable.

Connect the McAlpine shallow trap directly to the sink, it will run horizontally away from the sink outlet run parallel to the wall. This puts the McAlpine outlet some way from the pipe coming out of the wall hence the next bit. So if you fit a 90deg bend on the end of the wall pipe you can have the McAlpine and the inlet to the 90deg bend running parallel to one another. You can then either fit a u-bend or a flexi to join the two together mounted in the horizontal plane. All the pipework will run roughly horizontal so you will need to arrange a small slope but that should be possible. There will be no pipework more than a few millimetres below the base of the McAlpine trap and this should clear the drawer

Plus one to that - I also think having too big a machine will mean it won't modulate down far enough for average temperatures and will end up cycling! I wonder why people size for the extreme cases and not closer to the most common. If your house is well insulated then running a few towel rails might be a better way to deal with the extreme case or with UFH run a Willis in line to handle the three days a year when the outside temp get seriously out of whack.

Can you not go away from the sink waste parallel to the wall with the McAlpine shallow trap and then come back to the pipe with a U-bend mounted horizontally, so just acts as a pipe, or just use a flexi like THIS one with a 90deg bend on the end of the wall pipe. That should keep it all above the draw.

Are you allowed to make a wooden (same material as door)/ metal ramp the shape as indicated by @Roger440 and then fix it down to make it 'permanent' .

H mmm several members of my family think this way - I think you are supposed to make an effort (well somebody is!)

Good question - Welcome to THE forum for people like us - they look great in the showroom but not sure about longevity. You can usually access them by removing the inner pane of glass and the double / triple glazed unit is on the outside. So servicing is possible in the ones I have seen.

Can you see all the way to open sky through that crack?

Interesting I was taking to our insurance company and they are reckoning we need around £4K /sqM as a rebuild estimate for ours, also in SE! So somebody knows something I guess.

Yes - seen it, sadly my work for the block has gone on the back burner as work, build, family, looking after friends with issues and otherwise life has slowed me down. Will get back to it though. I did play with ESP-NOW to help a student with their project last session, worked well but limited number of nodes in network if you want security (and that is pretty basic) but sounds like a good fit for @Radians challenge.

Hi. You can go onto the land registry and register an interest to stop them getting it or saying it has been in their possession, for a long time. Essentially they will need exclusuve use, and to fence it for 10 years then they must advertise for the owners to come forward and then wait two further years. So it's a long way off but that does not solve the immediate problem for that you need legal advice.

Which one?

Crumbs - that sounds awful. Usually the two dwellings, yours and theirs, have separate water and electric systems but this does not sound to be the case. You probably need to get it checked by your water and electricity suppliers.

I dimly recall that in early schemes the payment was made on some notional export amount as they had no way of actually measuring it - smart meters tend to sort this one but may not have in your case. SO maybe yes / maybe no!

Looks like a little job for an Rpi, some current transducers, a small UPS, and a couple of contactors to shut the DC down as the grid power is turned off and then bring it back up in the correct order when power is restored. MIght work with a simpler scheme of just driving the DC contactors from the mains with a small on delay. Wish I had time to play.

Not sure cables are large enough for much power are they? It looks like some sort of controlled heat exchanger hot water, from some where else (is there anywhere else heat is coming from?) and some sort of valve and pump control the UFH circulation. Can you get the cover off?

Is there anything written on the box? No LED ON indicates not running, is there a thermostat somewhere that is not calling for heat or some time switch set to off?

Where did you find that figure - I was wondering how it would work for E7.

The big housebuilders are now getting into it - fully automated factories making Pods. https://www.property118.com/the-first-of-22-berkeley-modular-homes-are-being-built-in-greenwich/ an more on this here: https://www.berkeleygroup.co.uk/about-us/who-we-are/our-brands/berkeley-modular

Welcome to THE forum for people like us!

Just tell them you want it gone and let them worry about how to make it look right as I suspect that is what they are worried about.

Would anybody die in a ditch if we edit the title of this thread to read: "Relocating boiler to under-stairs cupboard"?

And what about those of us on LPG I wonder.
