Recent project: House Extension in Tooting – Massingberd Way
In September 2026 we completed a house extension and kitchen refurbishment on Massingberd Way, Tooting. The work brought the new extension and the existing kitchen and living area together as one space, with a German-made Häcker kitchen, quartz worktops, Amtico herringbone flooring, and improved heating, lighting and ventilation. We also managed the party wall process with the neighbouring property.

Building work we do in Tooting and Balham
- House extensions – rear, side return and wraparound extensions for Victorian and Edwardian terraces.
- Loft conversions – rear dormer, L-shaped and hip-to-gable lofts.
- Zinc and aluminium roofing – standing seam roofs for extensions and dormers, a popular finish on period homes.
- Full refurbishments – kitchens, bathrooms, rewiring, heating and complete house renovations.
Building on Tooting and Balham’s period homes
Most homes in Tooting and Balham are Victorian and Edwardian terraces and semis, including streets on the Totterdown Fields estate and around the Heaver estate. These houses suit side return extensions and rear dormer lofts, but they come with shared party walls, narrow side access and, in some streets, conservation area rules. We plan for these from the start: party wall notices, structural steel, skip and material access on busy residential roads, and working with Wandsworth Council on planning or permitted development.
