Party walls and building work
You must tell your neighbours if you want to carry out any building work near or on your shared property boundary, or ‘party wall’, in England and Wales.
Party walls stand on the land of 2 or more owners and either:
- form part of a building
- don’t form part of a building, such as a garden wall (not wooden fences)
Walls on one owner’s land used by other owners (2 or more) to separate their buildings are also party walls.
You can also have a ‘party structure’. This could be a floor or other structure that separates buildings or parts of buildings with different owners, eg flats.
