Builders in Balham & Tooting
Side return extensions, dormer loft conversions and full refurbishments for the Victorian and Edwardian terraces of Balham and Tooting.
What we build in Balham and Tooting
Just south of Clapham, Balham and Tooting are rows of Victorian and Edwardian terraces, with larger houses around Tooting Bec and Wandsworth Common. Most families here want the same things: a bigger kitchen through a side return, a bedroom and bathroom in the loft, and a house that works for modern life.

The side return and loft combination
On a typical Balham terrace, the side return is the narrow strip beside the back addition. Building into it, usually with a glazed roof, turns a galley kitchen into a wide kitchen and dining space. Many are permitted development, but not in a conservation area or on a flat.
Add an L-shaped dormer in the loft and the house gains a bedroom and en suite without losing garden. We plan the staircase, fire safety and steels at the start, which is what keeps these jobs on time. See our extensions and loft conversions pages for more.
Questions about building in Balham and Tooting
Do you work in Tooting Bec and around Wandsworth Common?
Yes, along with Balham, Tooting, Furzedown, Earlsfield and Clapham South.
How long does a side return extension take?
Usually about 10 weeks on site for a single-storey side or rear extension, depending on size and spec. You'll get a programme with your quote.
Can you do the extension and loft at the same time?
Yes, and it often saves time and money, as the scaffold, steels and building control visits are shared. We'll phase it so the house stays as livable as possible.
