ToggleWhat is a boundary and how close can you build an extension?
A boundary represents the point that separates one property from another and can include walls, fences, or other structures. When planning to build an extension, understanding the rules and regulations regarding boundaries is crucial. In most cases, you can build your extension up to 50mm from your neighbour’s boundary if you have either Permitted Development Rights or Planning Permission.
This distance may vary depending on the specific regulations set by local authorities. It’s important to consult with your local planning department to ensure compliance. However, if you can secure a Party Wall Agreement with your neighbour, you may be able to build your extension right on the boundary line, maximising the available space for your project.
Securing a Party Wall Agreement is not always guaranteed and may require additional negotiation and legal processes. However, it can be a beneficial option for those looking to optimise their extension ideas and maximise the available land.
Considerations for building near boundaries

When planning to build an extension close to a boundary, it is important to take into account several key considerations. One of the first things to consider are the permitted development rules, which dictate certain conditions that must be followed. These rules may include restrictions on the maximum height and distance from the original rear wall. Adhering to these rules is crucial to ensure compliance with local regulations.
Boundary restrictions are another aspect that should not be overlooked. Planning officers often apply a “45-degree rule” to evaluate whether an extension would encroach on the privacy or sightlines of neighbouring properties. This rule helps ensure that the proposed extension maintains an appropriate level of privacy and does not negatively impact the surrounding properties.
If you are planning to build your extension on a shared boundary, securing a party wall agreement may be necessary. This agreement outlines the rights and responsibilities of both you and your neighbour and helps prevent disputes during the construction process. Open communication and seeking agreement with your neighbours is vital to maintaining positive relationships throughout the project.
Lastly, design considerations play an important role in creating a successful extension. It is essential to consider the overall impact of the extension on access to gardens, natural sunlight, and the aesthetic compatibility with the existing property and its surroundings. Creating a design that seamlessly integrates with the existing structure can enhance the overall appeal of the property.
