Georgian townhouse stock in Wandsworth responds best to extensions that respect the existing rhythm. For Victorian and Edwardian period property, side returns and rear infill are routine. For 1930s suburban, single-storey rear and loft conversions dominate. We design to the block, not the brochure.

Which Wandsworth postcodes does this Georgian townhouse project service cover?

Every Wandsworth postcode district we draw in, the stock that dominates it and the authority that validates a Georgian townhouse project there. Wandsworth fees below are the statutory England rates for 2026, not Georgian townhouse project estimates.

PostcodeAreaDominant stockWhat it means for a Georgian townhouse project
SW15Putney / RoehamptonEdwardian terraces, Victorian villas, mansion blocksA Georgian townhouse project at an SW15 address in Putney / Roehampton is determined by Wandsworth Council under its own Local Plan policies for Putney / Roehampton.
SW17Tooting / EarlsfieldEdwardian terracesA Georgian townhouse project in Tooting / Earlsfield may land with Wandsworth Council or Merton Council — SW17 crosses the boundary, and the SW17 policies map decides it street by street.
SW18Wandsworth / Earlsfield / SouthfieldsVictorian villas and terracesWandsworth / Earlsfield / Southfields sits wholly inside SW18, so Wandsworth Council validates every Georgian townhouse project submitted from an SW18 address.
SW4ClaphamVictorian terraces, Edwardian villasA Georgian townhouse project in Clapham may land with Lambeth Council or Wandsworth Council — SW4 crosses the boundary, and the SW4 policies map decides it street by street.
SW8South Lambeth / Nine ElmsVictorian terraces, new-build apartmentsSW8 straddles a boundary: South Lambeth / Nine Elms addresses fall to Lambeth Council or Wandsworth Council, so confirm which authority validates the Georgian townhouse project before submitting SW8 drawings.
SW16Streatham / NorburyEdwardian terraces, post-war flatsStreatham / Norbury is split at SW16. Either Lambeth Council or Wandsworth Council or Merton Council or Croydon Council can determine a Georgian townhouse project here, so the SW16 address is checked against both policies maps first.

SW11Battersea / Clapham JunctionVictorian terraces, mansion blocksBattersea / Clapham Junction sits wholly inside SW11, so Wandsworth Council validates every Georgian townhouse project submitted from an SW11 address.

What changes about a Georgian townhouse project in each part of Wandsworth?

Roof pitch, wall build-up and plot depth change every few Wandsworth streets, and each one changes what a Georgian townhouse project can achieve at that address.

How do conservation areas and Article 4 affect a Georgian townhouse project in Wandsworth?

How designation changes a Wandsworth Georgian townhouse project: Wandsworth Council maintains 45 conservation areas, including Nightingale Triangle, Wandsworth Common, Clapham Common West. Inside any of them a Wandsworth Georgian townhouse project cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Clapham Common West sets the tone for Wandsworth casework.

Wandsworth and Article 4: Article 4 for HMO conversions covering the whole borough. A Georgian townhouse project planned at a SW11 address is checked against that direction first; Wandsworth Council publishes the Wandsworth extent, and the SW11 line rarely follows the Wandsworth boundary you would expect.

The building fabric around Wandsworth: 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. A Georgian townhouse project in Wandsworth is scoped against that stock first. Our Wandsworth fixed fee starts at £840; the £1,750 Complete package runs the Wandsworth scheme through Wandsworth Council planning and building control in one go.
