Rear House Extensions

Rear Extension London

Atomic Build offers bespoke rear extensions for London homeowners. Our approach to building is fully featured and tightly integrated, with design, engineering, and building solutions all available in a single package. If you want to add space to your single storey or double storey home, a rear extension might be the answer.

You can add value and extra space to your home with a rear extension. While we also offer L shaped extensions, side extensions, and numerous other extension options, a rear house extension can be the easiest option from a planning and design point of view.

We offer a variety of extension solutions, including rear extensions for semi-detached houses and rear extensions for terraced houses. At Atomic Build, we combine experience and building expertise with a working knowledge of local planning laws, council requirements, and boundary and height limitations.

The Atomic Build advantage

At Atomic Build, we specialise in building and renovation projects to inspire your imagination. Our approach to building is based on customisation, with project consultants and team leaders communicating with you throughout the process. Rather than a combination of discrete services, we combine multiple services as a single integrated solution.

At Atomic Build, we combine vision and experience with attention to detail and technical expertise. The desired budget, scale, and timeline of your rear extension influence every part of the build, which is why we ask the right questions from the outset. Unlike many of our competitors, our extensive range of services helps us to recognise the bigger picture while also focusing on the details.
