Building Surveying : Party Wall

Terraced house with party walls

If you live in a semi-detached or terrace house you share a wall (or walls) with your neighbour - that is known as the party wall. It separates buildings belonging to different owners.

Where a wall separates two different size buildings, only the part that is used by both properties is considered to be a party wall. The rest belongs to the person on whose land it stands.

You must get your neighbour's agreement before you can start any building work on a party wall such as:

  • Extensions
  • Damp proofing works
  • Some internal refurbishment
  • Structural alterations

In some cases, excavating or constructing foundations for a new building within three or six meters of neighbouring properties will also need written agreement.

If you are the owner proposing to have the works carried out, you must identify whether the works are governed by the Act. If so, you must serve statutory notice on the adjoining owners and get agreement to the building programme, before you commence works.

We are able to advise you on your responsiblities and to obtain all approvals on your behalf.
