Can I stop our neighbours from building on to the already existing loft party wall that is between our houses ie can we do anything to ensure that they build just inside their boundary? I don't want to stop them extending but they have two dogs who bark incessantly from 6am to late evening. The owners refuse to do anything about it. I don't want our loft bedroom, which isn't affected by the noise,to be another area of the house where we will be disturbed. Any advice please?
