When it comes to maximising your home’s potential, few renovations are as effective as a side return extension. If you have an unused alleyway adjacent to your property, this type of extension can transform that dead space into valuable living area, whether you’re looking to create an open-plan kitchen, a cosy dining nook, or even a study. But before you dive into your exciting home project, it’s crucial to understand how much a side return extension will cost and what factors can influence the overall budget.
A side return extension refers to the addition of space to the side of your property, typically filling in the gap between your house and your boundary. This is particularly common in Victorian homes and Edwardian homes, where narrow alleyways often exist between properties. Unlike other types of house extensions, a side return allows you to expand without encroaching on your garden, making it an attractive option for homeowners who wish to retain outdoor space while increasing the interior area.

While it’s difficult to provide an exact figure for the cost of a side return extension due to the variety of factors at play, here are some average shell-cost estimates based on different configurations and locations:
A single-storey extension is the most common choice, providing additional space on one level. Typically measuring around 3m x 5m, this extension allows for a seamless transition from your existing living area.
This option is perfect for maximising space across two levels. A double-storey extension usually measures about 2m wide x 7m deep, providing ample room for additional bedrooms or a spacious bathroom.
Specifically designed to enhance kitchen space, a side return kitchen extension focuses on creating an open-plan layout, ideal for modern living.
Incorporating large glass panels, this extension floods the interior with natural light while maintaining a modern aesthetic.
These extensions are especially popular among homeowners in Victorian terraced houses, turning narrow alleyways into functional living spaces.

Before embarking on your side return extension journey, it’s essential to consider the planning permission and legal implications. While many side return extensions fall under permitted development rights, some may require full planning permission, especially if they’re in conservation areas or have specific height restrictions.
Generally, side return extensions can be built without full planning permission as long as they adhere to specific guidelines called permitted development rights. These home extension rules include not exceeding 3m in height (flat roof) and not extending more than 50% of the original width of the house.
If your project does not meet the criteria for permitted development, you will need to submit a planning application. This process usually takes around 8-12 weeks and costs between ÂŁ200-ÂŁ500, depending on your local council.
All construction work must comply with building regulations, ensuring safety and structural integrity. You will need building control inspections at various stages, which typically cost around ÂŁ400-ÂŁ1,400.
