Which postcode districts around Southwark do we cover for drawing package work?

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

PostcodeAreaDominant stockWhat it means for a drawing package
SE1Bermondsey / Borough / WaterlooGeorgian terraces, post-war flats, new-buildBermondsey / Borough / Waterloo is split at SE1. Either Southwark Council or Lambeth Council can determine a drawing package here, so the SE1 address is checked against both policies maps first.
SE5CamberwellGeorgian villas, Victorian terracesA drawing package in Camberwell may land with Southwark Council or Lambeth Council — SE5 crosses the boundary, and the SE5 policies map decides it street by street.
SE15Peckham / NunheadVictorian terraces, post-war estatesA drawing package at an SE15 address in Peckham / Nunhead is determined by Southwark Council under its own Local Plan policies for Peckham / Nunhead.
SE16Bermondsey / RotherhitheWarehouse conversions, Georgian terraces, new-buildSE16 covers Bermondsey / Rotherhithe only; Southwark Council handles the drawing package, and Bermondsey / Rotherhithe case officers apply the SE16 conservation-area map.
SE17WalworthPost-war estates, new-build towersA drawing package at an SE17 address in Walworth is determined by Southwark Council under its own Local Plan policies for Walworth.
SE21Dulwich VillageGeorgian villas, Edwardian villas (Dulwich Estate)Dulwich Village is split at SE21. Either Southwark Council or Lambeth Council can determine a drawing package here, so the SE21 address is checked against both policies maps first.
SE22East DulwichVictorian and Edwardian terracesSE22 covers East Dulwich only; Southwark Council handles the drawing package, and East Dulwich case officers apply the SE22 conservation-area map.
SE24Herne HillVictorian villas, Edwardian terracesHerne Hill is split at SE24. Either Lambeth Council or Southwark Council can determine a drawing package here, so the SE24 address is checked against both policies maps first.

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

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

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

Conservation areas covering Southwark: Southwark Council runs 43, and Dulwich Village, Peckham Rye, Borough are the ones Southwark owners meet most. A drawing package inside a Southwark conservation area loses permitted development, so the Southwark submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Bermondsey Street a drawing package is judged on the street elevation first.

Southwark and Article 4: Article 4 for HMOs borough-wide; additional Article 4 for office-to-residential in Bermondsey and Elephant & Castle. A drawing package planned at a SE1 address is checked against that direction first; Southwark Council publishes the Southwark extent, and the SE1 line rarely follows the Southwark boundary you would expect.

The building fabric around Southwark: Georgian and Regency in Bermondsey and Borough; Victorian terraces in Camberwell and Peckham; Dulwich Estate controlled housing; riverside new-build. Dulwich Estate private planning scheme affects much of SE21 and SE22; Southwark planning for rest of borough; strong heritage context. A drawing package in Southwark is scoped against that stock first. Our Southwark fixed fee starts at £840; the £1,750 Complete package runs the Southwark scheme through Southwark Council planning and building control in one go.

What happens if a Southwark property sits on a boundary?
