When planning construction or renovation work on your property, especially in urban areas where houses are built closely together, you may encounter the term "party wall."
It is crucial to understand what a party wall is, its legal implications, and how it impacts your project.
Definition of a Party Wall
A party wall is a shared wall that separates two adjoining properties. It sits on the land of two or more owners and can form part of a building or be a garden wall (excluding timber fences). Party walls are most common in terraced and semi-detached houses, where the wall is a structural element supporting both homes.
Types of Party Walls
There are three primary types of party structures:
Party Wall – A wall that straddles the boundary of two or more properties. It can either form part of one building (e.g., the wall between two terraced houses) or separate distinct buildings (such as semi-detached homes).
Party Fence Wall – A standalone wall that sits astride the boundary between properties, usually made of brick or stone. (Timber fences are not considered party fence walls under the Party Wall Act.)
Party Structure – Any structure that separates sections of a building approached via a common area, such as a floor or ceiling between flats or a partition wall in a converted property.
The Party Wall Act 1996
In the UK, the Party Wall etc. Act 1996 sets out the legal framework for preventing and resolving disputes related to party walls, boundary walls, and excavations near neighbouring buildings. The Act applies when work is carried out that may affect the structural integrity of a party wall or boundary.
Key Aspects of the Act:
Serving Notice – You must provide a written notice to all affected neighbours (known as "adjoining owners") at least two months before any work begins.
Agreement from Neighbours – If your neighbour agrees in writing, you can proceed without needing a party wall award. If they do not agree, a surveyor must be appointed to negotiate terms.
Role of Surveyors – If an agreement is not reached, each party must appoint a surveyor (or agree on a single "agreed surveyor") to act impartially and draft a party wall award. This legally binding document outlines the scope of the work, how it will be executed, and who is responsible for any costs.
Consequences of Non-Compliance – Carrying out work without serving notice or obtaining necessary agreements violates the law and can result in legal action from your neighbour.
Common Party Wall Works
You may need a party wall notice if you plan to:
Cut into a party wall (e.g., for a loft conversion).
Insert a damp-proof course.
Raise a party wall or remove projections that prevent this.
Demolish and rebuild a party wall.
Underpin the foundations of a party wall.
Excavate within 3 metres of a neighbouring building, if digging deeper than their foundations.
Excavate within 6 metres of a neighbour’s building, where the excavation could undermine their foundations at a 45° downward angle.
Benefits of the Party Wall Act
Avoids Disputes – The Act establishes a clear legal framework for resolving disputes, ensuring fairness for all parties.
Legal Protection – Following the Act protects homeowners from future claims by ensuring that neighbours have been formally notified.
Preserves Structural Integrity – Ensuring work is done correctly protects both properties from damage caused by improper construction methods.
Steps to Comply with the Party Wall Act
Serve Notice: Provide written notice to your neighbours at least two months before starting work.
Obtain Consent: If your neighbour agrees in writing, you can proceed. If not, a surveyor will need to prepare a party wall award.
Appoint a Surveyor: If there’s a dispute, you (and possibly your neighbour) must appoint a surveyor to create an award detailing how the work should be carried out.
Follow the Agreed Terms: Carry out the work in line with the agreement to avoid penalties or legal action.

Understanding party walls and the legal responsibilities under the Party Wall Act 1996 is crucial for homeowners planning renovations or construction work. The Act provides a clear framework to help avoid disputes, protect property values, and ensure safety during building projects.
