Why Clapham homeowners pick 2VP.

Clapham's stock of Victorian and early Edwardian terraces around Clapham Common and Old Town is a natural fit for loft conversions and rear extensions. Lambeth's planning department is generally accessible, and the area's relatively open loft profiles mean most standard conversions proceed under Permitted Development.
