- Full design-and-build for side-return, rear, wraparound and double-storey extensions — structure to finished, decorated space.
- Building-control compliant construction with structural work coordinated in-house.
- Often combined with a kitchen renovation to create an open-plan kitchen-diner in one managed programme.
A well-built extension is the most effective way to add space and lasting value to a London home. We handle the build end to end — foundations, structure, roof and glazing through to plastering, flooring and decoration — so you get a finished, usable room rather than a shell. Side-return, rear, wraparound and double-storey extensions are all delivered by one managed team, coordinated with any kitchen or bathroom work in the same programme.
