Understanding Party Wall Notices and Proposed Building Works by Neighbors

When it comes to property ownership, it's not uncommon for neighbors to undertake building works that may impact the shared boundaries between properties. In such cases, a Party Wall Notice is typically served to inform adjoining property owners about the proposed works and seek their consent or agreement. This article aims to provide a comprehensive overview of Party Wall Notices, their purpose, legal requirements, and the rights and responsibilities of property owners involved.

What is a Party Wall Notice?

A Party Wall Notice is a formal communication served by a property owner (the "Building Owner") to neighboring property owners (the "Adjoining Owners") in accordance with the Party Wall etc. Act 1996 (the "Act"). This notice informs the Adjoining Owners about the intended building works that may affect the shared party wall, boundary, or adjacent structures.

Purpose and Importance of Party Wall Notices:

Notification: The primary purpose of a Party Wall Notice is to inform Adjoining Owners about the proposed building works. It ensures that all parties involved are aware of the intended changes and can prepare accordingly.

Agreement and Consent: The notice provides an opportunity for Adjoining Owners to give their consent or raise objections regarding the proposed works. It promotes dialogue between neighbors to resolve potential disputes and establish mutually agreeable terms.

Types of Works Covered by Party Wall Notices:

· Construction of new walls on the boundary line.

· Structural alterations to existing party walls.

· Excavation works near existing foundations.

· Building work that affects shared chimneys, flues, or other projections.

· Any other work that may affect the stability or structure of an adjoining property.

Serving a Party Wall Notice:

Timeframe: The Building Owner must serve the notice at least two months before the intended works commence, as stipulated by the Act.

Contents of the Notice:

a. Description of the proposed works.

b. The anticipated start date of the works.

c. The name and address of the Building Owner.

d. A statement outlining the rights of the Adjoining Owner(s) and the requirement to respond within a specified timeframe.

e. The option for the Adjoining Owner(s) to either provide consent or dissent to the proposed works.

Rights and Responsibilities of Adjoining Owners:

Consent: If an Adjoining Owner consents to the proposed works, it is advisable to do so in writing to ensure a clear record of agreement.

Dissenting to the Notice:

a. Appointing a surveyor: If an Adjoining Owner dissents to the Party Wall Notice, they can appoint a surveyor to act on their behalf.

b. Party Wall Award: The surveyor(s) will prepare a Party Wall Award, which outlines the rights and responsibilities of both parties and the manner in which the proposed works should proceed.

Resolving Disputes:

Surveyor's Role: In case of disagreement, the appointed surveyor(s) act impartially to resolve disputes and safeguard the interests of both parties.

Mediation and Arbitration: If the surveyor(s) fail to reach a resolution, alternative dispute resolution methods such as mediation or arbitration can be pursued.

Legal Implications:

Failure to Serve a Notice: If the Building Owner fails to serve a Party Wall Notice, Adjoining Owners can seek legal recourse to halt the works or claim damages.

Legal Protection: The Act provides legal protection for both Building Owners and Adjoining Owners, ensuring that their rights and interests are safeguarded throughout the process.


Party Wall Notices play a crucial role in maintaining neighborly relationships and resolving potential disputes arising from building works. By understanding the purpose, legal requirements, and rights and responsibilities associated with Party Wall Notices, property owners can navigate the process effectively, fostering open communication and preserving the integrity of shared boundaries.
