What we deliver in Wandsworth Town
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.
Rear extensions transform period and post-war houses; wrap-around projects include internal reconfiguration.
Dormer and mansard conversions add bedrooms; flat-roof post-war homes allow easy upward extensions.
On vacant plots between older buildings we design modern family homes that respect the street’s scale.
