Where in Wandsworth does a drawing package actually get determined?

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

PostcodeAreaDominant stockWhat it means for a drawing package
SW11Battersea / Clapham JunctionVictorian terraces, mansion blocksA drawing package at an SW11 address in Battersea / Clapham Junction is determined by Wandsworth Council under its own Local Plan policies for Battersea / Clapham Junction.
SW12BalhamVictorian and Edwardian terracesA drawing package in Balham may land with Wandsworth Council or Lambeth Council — SW12 crosses the boundary, and the SW12 policies map decides it street by street.
SW15Putney / RoehamptonEdwardian terraces, Victorian villas, mansion blocksA drawing package at an SW15 address in Putney / Roehampton is determined by Wandsworth Council under its own Local Plan policies for Putney / Roehampton.
SW17Tooting / EarlsfieldEdwardian terracesSW17 straddles a boundary: Tooting / Earlsfield addresses fall to Wandsworth Council or Merton Council, so confirm which authority validates the drawing package before submitting SW17 drawings.
SW18Wandsworth / Earlsfield / SouthfieldsVictorian villas and terracesSW18 covers Wandsworth / Earlsfield / Southfields only; Wandsworth Council handles the drawing package, and Wandsworth / Earlsfield / Southfields case officers apply the SW18 conservation-area map.
SW4ClaphamVictorian terraces, Edwardian villasA drawing package 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 drawing package before submitting SW8 drawings.
SW16Streatham / NorburyEdwardian terraces, post-war flatsSW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the drawing package before submitting SW16 drawings.

How does a drawing package differ street by street across Wandsworth?

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

What local planning policy applies to a drawing package in Wandsworth?

Conservation areas covering Wandsworth: Wandsworth Council runs 45, and Tonsley, Magdalen Park, Nightingale Triangle are the ones Wandsworth owners meet most. A drawing package inside a Wandsworth conservation area loses permitted development, so the Wandsworth submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Clapham Common West a drawing package is judged on the street elevation first.

Wandsworth and Article 4: Article 4 for HMO conversions covering the whole borough. A drawing package 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.

Wandsworth housing stock: 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. Read that before choosing a drawing package route in Wandsworth — construction, not postcode, sets what is achievable. Architectural drawings in Wandsworth start at £840 on a fixed fee, or £1,750 for the Complete package covering both Wandsworth Council submissions.

Who decides a drawing package on the edge of Wandsworth?

Sources for this Wandsworth drawing package page: borough policies maps and conservation-area registers (2025–26), Royal Mail postcode district boundaries, the Town and Country Planning (Fees for Applications) (England) Regulations, the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended, and the Party Wall etc. Act 1996.
