Yep. The wall will get built up and the house will look as good as new. Pain in the arse but will get over it.
The neighbours will have a good deal more rebuilding to do though.
You'll be expecting the neighbours to pay for your damage and they might contest?
Surely easier to make sure that they have all the proper planning permissions and party wall agreements signed by you so that work is done in a controlled way with your agreement so that if anything goes wrong they are liable. You actually wouldn't just let them get on with it - you'd get your risk mitigation and contingency plans in place before they started.
