Simple. Don't fit a dedicated UFH loop for the plant room, but lay the connecting pipes to other rooms spread out as if they were actually used for heating (not all bunched up together as seems normal) And for no extra cost or effort you get some heat into the floor of the plant room whenever any other room is heating.

What is that "support beam" supporting? It looks too tiny to be doing anything as a "beam"

If you have done first fix and fitted all the vents and ducts, then you have bought and installed the expensive bit. I found the actual MVHR unit cost less than the ducting so you might as well buy it and fit it. For a good portion of the year we sleep with the bedroom window slightly open, but that won't ventilate the whole house so we leave the mvhr on.

No problem, sometimes the shade it creates is welcome. Definitely a well liked and used space.

Dumb question. Is there no water coming out of the hot tap? Or is the "hot" water coming out cold? Not such a dumb question when I as an electrician drove 40 miles for "no hot water" expecting an immersion heater fault, only to find no water coming out of the taps and they needed a plumber.

One of the plumbers will advise I am sure but if you could take another photo with the pipe insulation removed they will see what joins to what more clearly. You have an interesting mixture of actuators. I assume as a result of failures and replacements?

Where are you? Which country? You definitely need one if in Scotland?

Loch Ness is the largest volume of fresh water in the UK, largely thanks to it's depth. It is not the largest surface area of fresh water though. You have to be very hardy to swim in the loch, it's only about 6 degrees and does not vary much. 73cm drop might require some dredging in Loch Dochfour to maintain navigation depth of 3 metres, and adjustment of the weirs to maintain some flow into the River Ness. For context, Loch Ness on a good day.

The traditional usage was pump water up whenever there was surplus and let it down again to generate to fill in the peaks, often for short periods like the late afternoon peak. If longer term storage is intended like to to fill in when there is no wind in the middle of winter then it may need to generate for a week, so would have to be at a very much lower power. I wonder how the Calley canal will cope with the rise and fall, some parts of Loch Dochfour approaching the top lock at Inverness are not that deep and the overfall over the weir keeps the River Ness flowing down through Inverness. Pump too much out of Loch Ness and boats may get stuck and the River Ness through Inverness will dry up. I am sure this has been thought about.......

What are your pre comencement conditions? Ours said we must first create the access from the highway before building work starts. So I created the access and the council confirmed in writing that by doing so the development had started.

Scotland generates most of the renewable wind and hydro power yet we as customers pay the highest prices. SOMETHING has to change. I say we have enough wind farms and there should be no more until the major hills in England like the Cotswolds, Chilterns, Berkshire downs, South Downs etc have the same windfarm density as we have. Build the windfarms nearer where the power is used rather than 400 miles away with more pylons to take the power down south from here.

Sorry misunderstood. Choose a flat metal plate screwed switch (not screwless with clip on cover) and carefully file 2mm off one end of the plate until it fits.

What depth is the back box. Is the "cover" you talk about the light switch? Can you find one that needs less depth (like they all used to when the standard light switch box was 16mm)

Also too deep and you might be below the water table in winter.

One thing I did for possible future runs, is in all the upstairs rooms I put a half board removable section of floor board at each end of the room, so 300mm wide, only screwed down and tongue or groove modified so it can be lifted. This will give access to the posi joist ends and allow additional cables to be pulled through around the room. Your spare conduits could be fitted in the walls as straight runs terminating in this accessible under floor space.

You can get swept bends for conduit which will work https://www.ebay.co.uk/itm/145467409061? Secure the conduit runs well, you don't want it coming apart if trying to fish a wire down later when it is inaccessible. Consider solvent welding the fittings to make sure.

My guess is no. You would need to reduce the height of that to be level with the road, which then creates the very real possibility you would be undermining the foundations of the house unless you are SURE they are a lot deeper than that. Then the parking created would be parallel to the house not what is more normal. It's one of those "I would not start from here" situations. I would never have bought that house because of this issue.

Again hard to visualise without plan and section drawings, but could you not get one more step on the first flight onto a 900mm deep half landing meaning one less step on the second flight and a larger landing at the top? Play with the on line stair design tools on stairbox and many others to find a solution.

Excellent news. I would peg it out on the ground with a length of rope and take photographs to show how much of which hedge might need a trim. I guess the thing here is not really needing to actually go and trim the hedges, but to get the condition removed from planning, and to know if the hedges are left to grow too close to the road, you can get them trimmed.

What nobody has mentioned yet, is if you cut any of the pipes to reconfigure the run to move the drain, then make sure you chamfer the outer edge of the cut so it feeds into the seal gently (with the correct silicon lubricant as already mentioned) Trying to insert a blunt square edge cut is a common reason for damaging the seal.

I know people say these Charles Austen pumps are the best but I am not convinced. They are basically a permanent magnet osciliating inside an coil which created a 50hz alternating magnetic field. The diaphragm at each end, is not only what does the pumping but that is ALL that supports the armature which is all the time trying to pull itself in contact with the stator. As soon as the diaphragm starts to age the first sign of a split and the magnetic force of the armature just tears it quickly and then the armature is stuck rubbing against the stator and hence all the red dust. It can go from seemingly working to broken very quickly. The other thing that annoys me the CE pumps I have only found the service kit as a package which included a new permanent magnet armature. It seems impossible just to buy the diaphragms. Other makes of similar pump do let you buy the individual parts and for less money. My argument in my other thread was for the price of the service kit I could by a complete pump of a different design. It was just that I could not find anybody reporting it works in this application. Now I know this piston pump works I am tempted to buy a second one to keep for when the first fails, which it will do at some point. And when it does I will dismantle it and see if there is any repair prospect, I suspect there won't be. I make weekly inspection (when I remember) which is basically unscrew the lid on the emptying point of the Conder and make sure I can hear it blowing bubbles. Then I know all is well.

Almost certainly it will be the diaphragms that have perished. They can be serviced, but I replaced them in mine and the replacements only lasted a year, very disappoionting. I had a thread on it recently and instead I chose to swap it for a very cheap Chinese piston pump to see if that was more reliable than a diaphragm pump. One thing I did because I did not know how long mine had not been blowing was contrived a long air line and connected my garage compressor to blow through it in case any sludge had settled, before connecting the new pump.

You need to find something you know the distance of like the width of your plot and scale from that to work out the actual scale.

That looks like a wet room so if it was done properly there would have been a proper tanking membrane on the floor and lapped part way up the walls before the tiles went down. So most likely a leak from the waste pipe?

What about if you measure to the middle of the road?
