March 20, 2024In Party Wall Advice


Embarking on construction projects that involve building new walls along the boundary with an adjoining property requires a comprehensive understanding of the Party Wall etc. Act 1996. This guide will delve into the specifics of Line of Junction Notices, a crucial aspect of the party wall process. From the necessity of serving notices to the implications of dissent and the potential involvement of party wall surveyors, we will unravel the complexities surrounding this particular type of notice.

I. The Essence of Line of Junction Notices:

A.Definition and Scope:

Line of Junction Notices come into play when undertaking construction work that involves building a new wall along the boundary with an adjoining property. This can include walls that are partly on the builder’s land and partly on the neighbour’s land or walls wholly on the builder’s land but immediately adjacent to the boundary.

B.Examples of Necessity:

  • Constructing an extension where the wall touches or straddles the line of junction with the neighbour’s land.
  • Building a garden wall where none exists (Note: The Act doesn’t cover fences).

II. Serving Line of Junction Notices:

A. Timelines and Procedures:

When planning such construction, the builder must serve a Line of Junction Notice on the neighbour at least one month before the proposed works commence. This allows the neighbour ample time to consider the plans and respond accordingly.

B. Neighbour’s Response:

After receiving the notice, the neighbour has 14 days to respond, either consenting to the proposals or dissenting. Failure to respond within this period is considered automatic dissent.

C. Implications of Dissent:

If the neighbour dissents, the builder is restricted to constructing the proposed wall solely on their land, not encroaching onto the neighbour’s property. This emphasises the importance of obtaining consent within the specified timeframe.

III. Building Owners’ Rights and Responsibilities:

A. Construction of Foundations:

The Act grants building owners the right to construct foundations under the neighbour’s land if deemed necessary for the project. This provision ensures flexibility in construction while adhering to legal frameworks.

B. Disputes and Resolution:

Any disputes regarding the position of the wall or the necessity for foundations can be addressed through the appointment of party wall surveyors. These professionals play a crucial role in preparing and agreeing on a party wall award, resolving contentious issues through a formal process.

C. Party Wall Awards:

The party wall award is a comprehensive document prepared by surveyors, determining the requirements for foundations and the precise position of the wall. It serves as a legally binding agreement, providing clarity and resolution to potential disputes.

IV. Practical Considerations and Best Practices:

A. Communication and Collaboration:

Open communication between the building owner and the neighbour is essential for a smoother process. Collaborative discussions can lead to mutual understanding and consent.

B. Professional Guidance:

Seeking professional advice, especially from party wall surveyors, ensures compliance with the Act and minimises the risk of disputes. Their expertise is invaluable in navigating the complexities of Line of Junction Notices.

C. Documenting Agreements:

Thorough documentation of agreements, including consents and dissent, is crucial for future reference and legal compliance. Clear records contribute to the transparency of the process.


In conclusion, understanding Line of Junction Notice under the Party Wall etc. Act 1996 is integral to a successful and legally compliant construction project. From serving Notices on time to navigating dissent and involving party wall surveyors when necessary, each step is pivotal.
