West London
More Space Without Losing Character
A successful West London extension blends harmoniously with original elevations: matching London stock brickwork, lime mortars, and slate roof pitches. Internally, we configure expansive kitchen-living areas with concealed structural steels.
We resolve drainage connections, Party Wall awards, and daylight angles prior to site setup, ensuring timely delivery.

Practical Homes for Modern Family Living
From dedicated home offices to seamless garden connections, we balance open-plan volumes with acoustic insulation and tailored joinery.
