The tilers should sort out the ridge when they do the lathing but they might say it’s not needed. The ridge normally just sits on the tiles so I am not sure what the square section is for?

It is difficult to see the dimensions but the kitchen looks small for the size of the house, particularly with the doors and thoroughfare to the living room. This is my kitchen area for comparison, cupboards and worktops on three sides, generous island with plenty of space around it and no thoroughfare.

It depends what roof covering will be and anticipated loading. Assuming you don’t want to engage a structural engineer, I would suggest looking at specifications of prefabricated garages and shed. The slope is more than adequate for a ‘flat’ roof, ie. felt or fibreglass covering. Wall plate should be the same width as the wall, 4” for a single brick/block.

The inspector didn’t show interest in any systems, apart from electrical test certificate. It may be as simple as opening the access chambers and flushing a toilet but I would wait until they ask.

My warranty inspector wasn’t interested in any systems except the electrics. It is unlikely the warranty will cover any equipment faults, they just want to know that you are not going to burn the place down!

My flipper panel was supplied separately but it may depend on the manufacturer. Suggest you find out the make and model and look at the hinge fixings, you should be able to take it off.

Happened to me twice, once at home and once in a hotel room, wasn’t anywhere near them at the time. It’s pretty much a spontaneous explosion, could be a combination of material fault and thermal expansion.

It’s difficult to see from the pictures but mine (different stove) just sits on top of the fire bricks both at the back and sides.

I have a MiTower+, easy to errect and really stable. Got a used one from FB marketplace, should be able to sell for the same price I paid but can’t part with it!

Correct, some are also described as ‘self bunded’

I would say open bunds are not commonly used in a domestic setting. Most tanks have an integral bund formed by a double wall design in a similar way to oil tankers (there may be some with secondary skins purely for protection so best to check specs).

You could ask a (trusted) builder to give an informal assessment/budget cost, to see if they think it’s a major problem?

Sounds like quite a large garage which they are concerned could become another house, a separate property. You should be okay with games/sun room and even a home office.

The internal photos seem to be a different location, not the other side of that arch. Did you take these photos? They are more than hairline cracks, I would be getting a structural engineer to look at it. Remedial cost could be anything depending on cause.
