A party wall is a wall shared by two adjacent buildings or properties. It forms part of the structure of both buildings, even if only a portion of the wall is structurally integral to each. This includes flank walls built against an existing structure; the shared section constitutes a party wall.
Key Characteristics of Party Walls:
- Shared Structure: The defining characteristic is that the wall is a structural element of both buildings.
- Boundary Location: The wall typically sits directly on the boundary line between the properties.
- Multiple Buildings: Party walls are common in buildings such as apartments, condominiums, townhouses, and terraced houses where shared walls are inherent to the design. They can also exist between detached buildings that share a wall.
- Legal Implications: In many jurisdictions, specific legal procedures and agreements (like Party Wall Agreements in England and Wales) govern alterations or work affecting party walls. This is to protect the rights and interests of both property owners.
Examples of Party Walls:
- Apartment Buildings: Walls separating individual units.
- Terraced Houses: Walls between adjacent houses.
- Attached Garages: The common wall between attached garages.
- Semi-Detached Houses: The shared wall between the two halves of the building.
Important Note: While the term "party wall" often implies a wall, it can also refer to other shared structures, such as roofs. If a roof is shared between buildings, it can be considered a party structure, and similar legal considerations apply. This is particularly relevant when undertaking renovations or major works that could impact the shared structure.
