Quite.
And now I have the cartoon image of there being a small, winding, void that ends in a pinhole in the adjacent property, and someone going hell for leather with the expanding foam whilst it fills up the while of next door. 
Anyway, next up is removal of a grim mouldy section
, and a knackered sagging
section, of the true ceiling that needs to be replaced. Fingers crossed the joists above that aren’t knackered.
Not expecting a full strip out of the remainder of the suspended ceiling, on the basis that they reckon a full skim should deal with the tie-in join.
^Photo for context of ceiling. Those carcasses are the tall ones removed from the wall, revealing damp/mouldy marks in the the built-in fridge and freezer bits
- they’re getting replaced, along with the wall cabinets.
. As is the whole of the worktop. And therefore the tiles, too, most likely.
In removing the appliances, they managed to chip a previously
door under the sink.
They reckon that can be fixed, rather than needing a new replacement. Hmmm. If a new door is required, then that could lead to new doors all round, and next to nothing from the room actually being retained! 
So, presuming the hidden joists are alright, I think that’s just about it apart from the reinstatement itself (at worst, there’ll be some minor haggling over something not being covered in the small print).
Oh, I forgot to ask about them installing new replacement appliances in place of the old ones if we buy them in. Seems like a missed opportunity to have a refresh like this but retain what are quite dated white goods (small washing machine, cramped fridge, a freezer that ices up… I guess the tumble dryer and dishwasher are ok).
