I am relating mainly to disruption. The high wall I will just have to cope with. There does not seem to anything I can do to stop this now.
The party wall is about 2 strides if that from kitchen window!
I think your slightly missing the point which is my tenants could leave due to the disruption and therefore I will lose income, or they could ask for a reduction in the rent and I am wondering whether I can negotiate compensation from my neighbour. The party wall act does not appear to allow for compensation. Do I have any other recourse under law if I lose income due to my neighbours development?
