South West London holds the city’s densest run of period houses. Chelsea and South Kensington stucco, Fulham terraces, Belgravia squares.

Most of our work here goes down or back. A new basement goes under the house. A kitchen extension goes behind it.

The design, the cost plan and the build sit in one contract. Our quantity surveyor prices the drawings line by line, so the figure stays honest.

We walk to most SW sites from the Fulham studio. Site meetings happen weekly, and you see the same faces throughout.
