What Is A Party Wall?

A party wall is a wall that is shared by two adjoining properties, often with separate owners. These walls serve as a division or separation between two buildings or land parcels. Party walls can be found in various types of properties, including townhouses, duplexes, and even commercial buildings with adjacent structures.

Key Characteristics Of Party Walls:

  1. Shared Ownership: Party walls are co-owned by the owners of the adjacent properties. This shared ownership means that both parties have certain rights and responsibilities regarding the wall.
  2. Boundary Marker: In some cases, a party wall serves as a boundary marker between properties. This is especially common in densely populated urban areas where buildings are closely situated.
  3. Common Structure: Party walls are typically structural elements that support the buildings on both sides. They may be load-bearing and essential to the stability of the structures.
  4. Legal Framework: Laws and regulations govern party walls to ensure that both property owners’ interests and the structural integrity of the wall are protected.

Why Party Walls Matter?

Party walls matter for several reasons, including:

  1. Property Division: Party walls delineate the boundary between two properties, preventing disputes over property lines and encroachments.
  2. Structural Support: Party walls often provide structural support to buildings on both sides. Ensuring their stability is crucial for the safety of the structures and their occupants.
  3. Rights and Responsibilities: The concept of party walls comes with rights and responsibilities for both property owners. These include the right to carry out work on the wall and the obligation to maintain it properly.

What Is The Difference Between A Boundary Wall And A Party Wall?

Although the terms “Party Wall” and “Boundary Wall” are often used interchangeably, the Party Wall Act makes the difference clear. A boundary wall is a wall that sits wholly on the land of one owner. Its piers are also on that same land. In contrast, a party wall lies astride the boundary line of two properties.
