A Homeowner’s Guide by MM Planning & Architecture

At MM Planning & Architecture, we understand that embarking on a construction or renovation project in London involves navigating a maze of regulations. Two critical legal requirements are build-over agreements and party wall notices. These regulations are essential for protecting your property and that of your neighbours, ensuring your project proceeds without disputes or delays. This guide will provide comprehensive information on build-over agreements and party wall notices, their importance, and the process of obtaining them.

What is a Build Over Agreement?

A build-over agreement is formal consent from your local water authority, permitting construction work over or near public sewers. This agreement ensures the structural integrity of the sewer system is maintained and that any future maintenance can be performed without hindrance.

When is a Build Over Agreement Required?

A build-over agreement is required if:

  • Your construction project involves building an extension over or near a public sewer.
  • You plan to modify the foundations of an existing building near a sewer.
  • You intend to install new drainage systems that connect to public sewers.

How to Obtain a Build-Over Agreement

  1. Application: Apply to your local water authority, including detailed plans of the proposed construction.
  2. Inspection: The water authority may inspect to assess the potential impact on the sewer system.
  3. Approval: Once the plans are satisfactory, the water authority will issue the build-over agreement.

Tips for a Successful Application

  • Ensure your plans are precise and comprehensive.
  • Consult with an architect or structural engineer to ensure compliance with regulations.
  • Plan for future access to the sewer for maintenance purposes.

Understanding Party Wall Notices

A party wall notice is a legal document that informs your neighbours of your intention to carry out work that might affect a shared wall or boundary. This notice is required under the Party Wall Act 1996, which aims to prevent and resolve disputes between neighbours.

Types of Party Wall Notices

  • Line of Junction Notice: Needed when building a new wall on the boundary line.
  • Party Structure Notice: Required for work on an existing party wall or structure.
  • Notice of Adjacent Excavation: Necessary when excavating near a neighbouring property.

How to Serve a Party Wall Notice

  1. Preparation: Draft the notice, detailing the planned work, start date, and duration.
  2. Serving the Notice: Deliver the notice to your neighbours at least two months before starting work.
  3. Response: Neighbors have 14 days to respond. They can agree, request modifications, or appoint a party wall surveyor.

Best Practices for Serving Notices

  • Serve the notice well in advance to allow time for negotiations.
  • Deliver the notice in person or via registered post to ensure receipt.

Legal Requirements and Compliance

The Party Wall Act 1996 provides a framework for preventing and resolving disputes between neighbours. It covers:

  • Building new walls on the boundary.
  • Work on existing party walls or structures.
  • Excavations near neighbouring buildings.

Compliance Tips

  • Understand your obligations under the Party Wall Act.
  • Keep clear records of all communications and agreements.
  • Consider appointing a party wall surveyor to facilitate the process.

FAQ

1. What happens if I don’t have a build-over agreement?

Proceeding without a build-over agreement can lead to legal issues and potential fines. It may also complicate future property sales, as prospective buyers will want to see that all necessary agreements are in place.

2. Can I start work before serving a party wall notice?

Work should commence once the notice is served and any disputes are resolved. Starting work without serving a party wall notice can result in legal action from your neighbours and potential delays.

3. How long does it take to get a build-over agreement?

The process can take a few weeks to a couple of months, depending on the project’s complexity and the water authority’s responsiveness. It’s important to factor this into your project timeline to avoid delays.

4. What if my neighbour refuses to consent to the party wall notice?

If a neighbour refuses to consent, a party wall surveyor can be appointed to resolve the dispute and create a party wall award. This ensures that work can proceed legally while addressing the neighbour’s concerns.

5. Are there any fees associated with build-over agreements and party wall notices?

Yes, there are typically fees for processing build-over agreements and for appointing party wall surveyors. These fees vary depending on the scope of work and professional rates. It’s advisable to budget for these costs in your project planning.
