What we build in Wandsworth
From the Toast Rack streets by Wandsworth Common to the Southfields Grid and the terraces of Earlsfield, Wandsworth is mostly Victorian and Edwardian family housing. That makes it ideal for side returns, rear extensions and loft conversions, which is most of what we're asked to quote for here.
- Side return and wraparound extensions
- Dormer and hip-to-gable loft conversions
- Full house refurbishments
- Kitchen and bathroom renovations
- Structural alterations
- Garden landscaping and patios

Extending a Wandsworth house
The Southfields Grid and the Toast Rack are full of houses with a side return and an unconverted loft, which is the combination that gives you the most for your money. A side return turns the kitchen into one wide room; a dormer adds a bedroom and bathroom without touching the garden.
Plenty of homeowners do both at once. That means one set of scaffolding, one round of party wall paperwork and one period of disruption rather than two. Our Wimbledon project went further still, combining a rear extension, a dormer loft, a full refurbishment and a new garden in a single 20-week build.
Questions about building in Wandsworth
Do you work in Earlsfield, Southfields and Tooting?
Yes, along with Wandsworth Town, Balham and the streets around Wandsworth Common.
Should we do the extension and loft at the same time?
If you can, it usually saves time and money overall: one scaffold, one party wall process and one period of disruption. It does mean a bigger budget up front and more time living with builders, so we're happy to price both options.
Do you help with planning drawings?
Yes. We work with trusted architects and structural engineers who prepare drawings, planning applications and building regulations packages, and we stay involved so the design is buildable and priced properly.
