Our neighbour did a loft extension and their builder has done an aesthetically poor job of building up the party wall. It is slanting upwards because the coping stones are too short. Their party wall surveyor is saying its structurally sound and we should not have any issues with the wall but we do not want to live with a wonky wall. Are we required to go with what their surveyor is saying i.e. live a wall which shows poor workmanship but is structurally stable? Eventually we have to pay the neighbour for raising the party wall if we also build into our loft but I would not be happy to pay for the wall as-is and would want to get it fixed. It is a shared structure and the neighbours builder should be fixing the wall ideally.
Have mentioned this to our neighbour already but will talk to them once they move back in.
Just trying to get a feel for what is acceptable and not in terms of raising the party wall. Does the party wall act make a distinction between aesthetics and structural stability?
