What is a Side Return Extension?

A side return extension is a type of home extension that extends into the unused space at the side of your property. This type of extension is particularly popular in London, where many homes have narrow, underutilised side returns. A side return extension can be used to create a larger kitchen, a dining area, or a living room, and can be designed to blend seamlessly with your existing home. We work with you to create a design that meets your needs and preferences plus adds value to your home.


Benefits of a Side Return Extensions

A side return extension is a popular way to add more living space to your London home. Here are some of the benefits of choosing a side return extension:

Improved functionality:

 By extending into the unused space at the side of your property, you can create a larger kitchen or living area that’s more functional and better suited to your needs.

Enhanced natural light:

 A side return extension can also improve the natural light in your home, making it brighter and more inviting.

Increased home value:

 By adding more living space and functionality to your home, you’ll also increase its value, making it a wise investment for the future.

Customisable design:

With a side return extension, you can customise the design to suit your specific needs and preferences. Whether you want an open-plan living area or a more traditional layout, we can help bring your vision to life. A side return extension makes use of an area that many families don’t use or can’t use due to its shape and size. These areas often have access issues as well so encompassing it into your homes footprint can be a great way to increase your internal living area without giving up useable outdoor space.

Regulations for Side Return Extensions

Before you decide to go ahead with a side return extension, it’s important to be aware of the regulations that govern this type of work. Some things to consider include:

Planning permission:

Depending on the size and scope of your extension, you may need planning permission from your local council. The Market Design and Build can help you navigate this process and ensure that your extension meets all necessary regulations.

Building regulations:

 Your extension will also need to meet certain building regulations to ensure that it’s structurally sound and safe to use. We have extensive experience in building regulations and will ensure that your extension is compliant with all necessary standards.

Party wall agreements:

 If your extension will affect a party wall (i.e. a wall shared with a neighbouring property), you’ll need to enter into a party wall agreement to ensure that the work doesn’t cause damage to the wall or neighbouring property. We are experts in helping you to navigate this process and to ensure that all necessary agreements are in place before
work begins.

Costs of Side Return Extensions

The cost of a side return extension can vary depending on a number of factors, including the size and scope of the work, the materials used, and the location of your property. At The Market Design and Build, we offer competitive pricing for side return extensions that are designed to meet your needs and budget. Our transparent pricing policy ensures that you’re aware of all costs associated with the project, and we’ll keep you informed of any additional costs throughout the process.

Here are some factors to consider when estimating the cost of your side return extension:


The design of your side return extension will have a significant impact on the cost of the project. More complex designs or unique features, such as bespoke finishes or floor-to- ceiling windows, may increase the overall cost.


The materials used for your side return extension can also impact the cost. High-end materials, such as natural stone or hardwood, will increase the overall cost, while more budget-friendly options, such as uPVC or composite materials, may help to keep costs down.


 The location of your property in London can also affect the cost of your side return extension. For example, if you live in a prime location, you may need to budget more for the work due to higher labour costs and material prices.

Site conditions:

 The site conditions can also impact the cost of your side return extension. For example, if your site requires extensive groundwork or has difficult access, the cost may be higher.


The timeframe for your extension will also affect the cost. The longer the project takes, the more you’ll need to budget for labour costs. At The Market Design and Build, we understand that cost is an important consideration for our clients. That’s why we work closely with our clients to find a solution that meets their needs and their budget. We provide transparent pricing and will keep you informed of any additional costs throughout the project.
