In addition to needing planning permission and building regulations approval, The Party Wall Act 1996 also applies to anyone carrying out:
- work on an existing wall or building shared with another property.
- building on the boundary with a neighbouring property.
- excavating within 3 or 6 metres of a neighbouring building or structure depending on the depth of the hole or proposed foundations
You must serve a statutory notice on all those defined by the Act as adjoining owners to get their agreement before you start work. The Act provides a framework for preventing and resolving disputes in relation to party walls, boundary walls and excavations near neighbouring buildings.
