Every Wandsworth postcode district we draw in, the stock that dominates it and the authority that validates a full project cost package there. Wandsworth fees below are the statutory England rates for 2026, not full project cost package estimates.
| Postcode | Area | Dominant stock | What it means for a full project cost package |
|---|---|---|---|
| SW15 | Putney / Roehampton | Edwardian terraces, Victorian villas, mansion blocks | SW15 covers Putney / Roehampton only; Wandsworth Council handles the full project cost package. |
| SW17 | Tooting / Earlsfield | Edwardian terraces | SW17 straddles a boundary: Tooting / Earlsfield addresses fall to Wandsworth Council or Merton Council, so confirm which authority validates the full project cost package before submitting SW17 drawings. |
| SW18 | Wandsworth / Earlsfield / Southfields | Victorian villas and terraces | SW18 covers Wandsworth / Earlsfield / Southfields only; Wandsworth Council handles the full project cost package. |
| SW4 | Clapham | Victorian terraces, Edwardian villas | SW4 straddles a boundary: Clapham addresses fall to Lambeth Council or Wandsworth Council, so confirm which authority validates the full project cost package before submitting SW4 drawings. |
| SW8 | South Lambeth / Nine Elms | Victorian terraces, new-build apartments | SW8 straddles a boundary: South Lambeth / Nine Elms addresses fall to Lambeth Council or Wandsworth Council, so confirm which authority validates the full project cost package before submitting SW8 drawings. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | A full project cost package in Streatham / Norbury may land with Lambeth Council or Wandsworth Council or Merton Council or Croydon Council — SW16 crosses the boundary, and the SW16 policies map decides it street by street. |
| SW19 | Wimbledon / Colliers Wood | Victorian villas, Edwardian terraces | Wimbledon / Colliers Wood is split at SW19. Either Merton Council or Wandsworth Council can determine a full project cost package here, so the SW19 address is checked against both policies maps first. |
| SW11 | Battersea / Clapham Junction | Victorian terraces, mansion blocks | Battersea / Clapham Junction sits wholly inside SW11, so Wandsworth Council validates every full project cost package submitted from an SW11 address. |
Roof pitch, wall build-up and plot depth change every few Wandsworth streets, and each one changes what a full project cost package can achieve at that address.
How designation changes a Wandsworth full project cost package: Wandsworth Council maintains 45 conservation areas, including Magdalen Park, Nightingale Triangle, Wandsworth Common. Inside any of them a Wandsworth full project cost package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Wandsworth Common sets the tone for Wandsworth casework.
What Article 4 removes near Wandsworth: Article 4 for HMO conversions covering the whole borough. Before pricing a full project cost package we check whether the SW11 address is inside the mapped area, because Wandsworth Council draws the Wandsworth boundary street by street rather than across the whole of Wandsworth.
What Wandsworth is built from: Extensive Victorian terraced streets — the classic London side-return extension opportunity; Edwardian villas around the commons; 1930s semi-detached in Southfields. Family-oriented, high side-return extension and loft conversion rates; planning department experienced with Victorian terrace modifications. That mix decides the full project cost package route in Wandsworth more than the postcode does.
