Housing stock in Wandsworth
Victorian and Edwardian terraces at scale — Tooting, Balham and Battersea are the classic rear dormer heartland.

Wandsworth has published clear extension SPDs and is one of the more predictable planning boroughs. Conservation zones (Nightingale, Battersea Park) tighten design review.
Party Wall Act — what to expect

Typical costs in Wandsworth
For a mid-spec 25 m² rear dormer loft conversion, all-in (structural design, building control, party wall, VAT and 12% contingency), expect roughly £125,000 to £185,000. A mansard, a hip-to-gable with high-spec en-suite joinery or a conservation-area application will push above the top of this range; a self-built rooflight conversion comes in well under the bottom.
