Question re: party wall rights
I'm planning to remove chimney breasts on 3 floors of a house (fireplaces taken out by previous owners). My architect and very experienced structural engineer say feasible and safe to do. However, neighbour that I share a wall with, and will at some point enter into a Party Wall Agreement (PWA,) is very anxious that the work involved will damage his property. He would like, in addition to hiring his own PW surveyor, to hire a structural engineer to check my engineer's work.
1. Does my neighbour have a right to hire an independent structural engineer in addition to a PW surveyor under a PWA? If yes, is this something that I would be expected to pay for under the PWA?
2. If for some reason his structural engineer disagrees with my engineer's opinion on the feasability of taking out chimney breasts in my house what happens e.g. does the decision go to another independent committee etc.? What is the arbitration process?
Thanks in advance for any helpful information
