SE21 primarily covers Dulwich Village in Southwark. It also touches Lambeth.
Decisions for SE21 are made by Southwark Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Southwark: Yes.
Building regs from £950. We do not charge hourly. Free site survey across all SE21 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Southwark Council timelines align with the national norm.
Dulwich Village in SE21 is characterised by the housing stock of Southwark — broadly georgian and regency in bermondsey and borough.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SE21 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SE21 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SE21 | Dulwich Village | Georgian 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. |
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | Adjoining district to SE21, also inside Southwark for drawing package purposes. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | Adjoining district to SE21, also inside Southwark for drawing package purposes. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | Adjoining district to SE21, also inside Southwark for drawing package purposes. |
| SE16 | Bermondsey / Rotherhithe | Warehouse conversions, Georgian terraces, new-build | Adjoining district to SE21, also inside Southwark for drawing package purposes. |
| SE11 | Kennington / Vauxhall | Georgian terraces, post-war estates | Adjoining district to SE21, also inside Lambeth for drawing package purposes. |
| SE24 | Herne Hill | Victorian villas, Edwardian terraces | Adjoining district to SE21, also inside Lambeth for drawing package purposes. |
| SE27 | West Norwood / Tulse Hill | Victorian terraces, Edwardian villas | Adjoining district to SE21, also inside Lambeth for drawing package purposes. |
| SW2 | Brixton Hill / Tulse Hill | Victorian terraces, post-war estates | Adjoining district to SE21, also inside Lambeth for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SE21 streets, and each one changes what a drawing package can achieve at that address.
