Understanding Party Walls: What Every Property Owner Should Know

A party wall is a shared structure—typically a wall dividing two adjoining properties such as terraced or semi-detached houses. These walls are common in densely built areas and are jointly owned by the neighbouring property owners. They provide structural support and separation, while legally allowing shared use.


Key Facts About Party Walls

Shared Ownership
Both property owners have equal rights and responsibilities over the party wall. This includes upkeep, repairs, and alterations.

Legal Rights and Responsibilities
These are usually set out in a formal document called a Party Wall Agreement (or Party Wall Award). It defines how maintenance or building works should be handled and how associated costs are divided.

Different Types of Party Wall
Examples include:

  • The dividing wall between two terraced homes
  • A wall between semi-detached properties
  • Internal walls or floors shared by separate units in a block of flats

More Than Just Walls
Party walls may also include:

  • Shared fences or boundary walls
  • Garden walls built astride a boundary
  • Floors and ceilings between flats in a multi-storey building

Legal Framework
In the UK, the Party Wall etc. Act 1996 governs how works affecting party walls must be managed. This legal framework protects both owners’ interests and helps avoid disputes.

Role of a Party Wall Surveyor
If there is disagreement or planned work impacting a party wall, a party wall surveyor can be appointed. Their role is to assess the situation, mediate fairly, and issue a Party Wall Award that all parties must follow.


Why It Matters

Whether you are a homeowner planning an extension or a professional advising a client, understanding the legal and practical aspects of party walls is essential. It ensures that any works proceed smoothly, lawfully, and with minimal disruption.
