Side Return Extensions in Surrey & South West London
Side return extensions make use of the often-wasted narrow passage down the side of Victorian and Edwardian terraced homes, significantly increasing your ground floor space.

Our Process For Side Return Extensions
We handle everything from initial design through to final completion. Your project starts with a site visit where we discuss your requirements and assess what’s possible. Our design team then creates detailed architectural drawings, which we submit for planning approval or building regulations as needed. Once approved, we provide a fixed-price quote covering all aspects of the build.
During construction, your dedicated site manager coordinates all trades and keeps you updated throughout. We handle structural work, electrics, plumbing, glazing, and all finishing trades. The result is a transformed ground floor that feels significantly larger and more connected.
Tell us about your plans for your home in Kingston, Wimbledon, Richmond, Esher, Cobham, Guildford and the surrounding areas. Our design and build team will guide you from first ideas through planning, approvals and construction.
