Neighbours are doing the standard knock through kitchen and dining room, sliding doors, autopsy table extension. Just been given party wall notice. No idea what to do - do we just say yes do it to keep the peace or do we contest it to protect our property? Bit fed up. Theyre going to move in with her parents and we are going to have to endure the building work for 3-4 months (at least). Any advice on how to respond would be much appreciated.
