How about...a sliding door in the room itself? https://www.homebase.co.uk/our-range/building-and-hardware/doors/internal-doors/cottage-doors?facets=Type%3DSliding The link above, just for ideas! You make the door then use cheap as chips door gear. https://www.toolstation.com/sliding-door-gear/p34159?

Girl on the radio the other day said she'd run out of things for her kid to do so sat him down in the garden gluing stones together with PVA...

My Aurora Enlite spots have a 60deg spread.

Looks like a solvent sniffer's squat that. Not my place, random pic off the web. I do however think of my place as before I do one room, somewhere else needs to be used for"temporary" storage. Always looking for that elusive empty room. Ground floor plan:

What are the walls of the new outhouse going to be made of, brick, block, timber? What's the external finish, render, battened and clad etc. Edit, just reread the OP. I'd use a wall starter: https://www.screwfix.com/p/sabrefix-wall-starter-kit-stainless-steel/56037?

Tell me that dog rough, ragged hole was already there?

That's coley isn't it?

Might well be several buried under the debris.

Lot of sheep to round up?

I don't use ptfe tape on compression fittings now just Jet Blue Plus.

Yep, apologies @pocster, ? looking really good there.

Shed loads of these trim routers on Banggood from £22 upward. Search "laminate router".

Dead testing should have shown up any NE faults tbh unless subsequent works have caused it.

I dream of no lippage! Get the LVT down and you won't notice it!

Neutral earth fault? You need it checking. Have you done all the dead tests? IR between N & E?

As long as pickled onions, red cabbage, pigs in blankets and sprouts are still available I'll be happy. SWMBO less so...

Could be as simple as a loose neutral somewhere. Worth checking all your CU connections INCLUDING the factory ones. Often overlooked. That and test the RCD along with a ramp test.

I thought the ban was one way? No restriction on the boatloads coming in as far as I'm aware. This 48 hour ban will allow the French to devote more time and resources to pointing them in our direction surely?

Can you get a look inside the guts of the NAS? I've seen some horrors in the enclosures of external kit, water literally running down components that then go t!ts up. Often a tell tale smell (like TCP).

Your MVHR isn't going yet is it? Might make a world of difference.

Raise the NAS up on some blocks for a bit. Could be the hot NAS / cold shelf interface.

Is it worth running a dehumidifier in there for a bit?

If it's not clogging up over quickly then isn't a case the enzymes or whatever are doing their thing? It took me 18 years here to actually find out where my cess pit is and that's only because the loos were backing up. A pink toothbrush seemed to be the culprit getting wedged sideways and acting as a wet wipe magnet. I had it emptied anyway when I found the access hatch but left a good slug in the bottom in the advice of the chap who said you don't want to lose all the "good stuff".

Putting a prv on like @Nickfromwales said stopped the dripping taps and ball cocks in the house. I kept the outside tap on the 8bar though.
