What we deliver in Tooting Bec
Every street sits differently — a period terrace, a post-war semi, a modern infill. We shape the recommendation around your actual house, its planning context and how you want to live.
Two-storey rear extensions create open-plan living and extra bedrooms; wrap-around projects are possible on wider plots.
Dormer and hip-to-gable conversions add bedrooms and home offices. L-shaped dormers can provide two new rooms in larger houses.
On corner sites or deep gardens we replace smaller bungalows with modern, energy-efficient homes.
