Are your or your neighbour carrying out building works? There is a good chance that you or your neighbour will have responsibilities under the  Party Wall etc Act 1996.


What is a party wall?

The main types of party walls are:

  • a wall that stands on the lands of 2 (or more) owners and forms part of a building – this wall can be part of one building only or separate buildings belonging to different owners
  • a wall that stands on the lands of 2 owners but does not form part of a building, such as a garden wall but not including timber fences
  • a wall that is on one owner’s land but is used by 2 (or more) owners to separate their buildings

The Act also uses the expression ‘party structure’. This could be a wall or floor partition or other structure separating buildings or parts of buildings in different ownership, such as in flats.

What the Act covers

The Act covers:

  • new building on or at the boundary of 2 properties
  • work to an existing party wall or party structure
  • excavation near to and below the foundation level of neighbouring buildings

This may include:

  • building a new wall on or at the boundary of 2 properties
  • cutting into a party wall
  • making a party wall taller, shorter or deeper
  • removing chimney breasts from a party wall
  • knocking down and rebuilding a party wall
  • digging below the foundation level of a neighbour’s property
