Construction halt because the wall collapsed? When to continue building?

I think there are enough cases where purely by chance during the work the one wall worth preserving was knocked down ;-) The office will know such cases by the dozens and therefore reacts allergic.

It doesn’t seem to me that the office is upset about the wall itself, but rather because it no longer sees significantly more than half of the original structure preserved, and thus considers it a black new build where only a renovation should have been done.

...I'm finding it very hard right now not to see the building authority as an opponent...

I wish you a good "hommmmmm" and in the end building officials who are receptive and believe you. Maybe the wall can be rebuilt in the old style. Then there would be no visual loss of the substance.

, you are probably right... However, I had assumed that it was also clear to them.
Thanks again for the great tips and the moral support.
