I'm doing a job for some folks who've just bought a grade II listed building. (Not loadsamoney: they could only afford it because it's got walls, floors, sort of a roof and that's about it.) Got scaffolding going up for roofing and today apparently part of the chimney stack fell down! Builder went up to look and apparently went white and said he'd get onto it tomorrow. I know this guy and he's not the teeth-sucking "oh dear that'll cost yer" type: if he says it needs fixing it needs fixing.
Meanwhile helpful folks at council got wind of it and came round with binoculars and digicam, looked at it from the ground and said it didn't need rebuilding. Mrs New Owner not too happy, council bods say get a structural engineer to assess it.
Now Bobski the builder will probably rebuild the damn thing for less money than a S.E. would charge for a report, so Mr & Mrs N.O. are inclined to just get Bobski onto it asap.
Q is: what bureaucratic misfortune could council jobsworths wreak on them if they're not happy with this? Assuming chimney is rebuilt as it was before?
