What Is a Party Wall?

Defining a Party Wall

A party wall is a wall or structure that physically stands on the boundary line between two neighbouring properties and is shared by both owners. It plays an important role in separating properties and supporting structures.

Common Examples of Party Walls

  • The shared wall between two attached houses such as terraced or semi-detached homes
  • Boundary walls that divide gardens or yards between neighbours
  • Shared structural features like chimneys or retaining walls

Party Structures Beyond Walls

The Party Wall etc. Act 1996 also covers “party structures,” which include floors and ceilings that separate flats or maisonettes within the same building.

Importance of Identifying Party Walls

Correctly identifying a party wall is important because specific rules and procedures apply when you plan work affecting these walls. The Act ensures that both property owners’ rights and interests are protected.

Implications for Building Work

If you intend to build, alter, or repair a party wall, you must follow the legal procedures under the Act, including serving notice to neighbours and potentially appointing party wall surveyors.

Why This Matters to Property Owners

Knowing whether a wall is a party wall helps avoid accidental breaches of the Act, which can lead to disputes, delays, or legal action.
