Bay-fronted suburban semis with hipped roofs and side passages. Dominant outer-London stock.
1930s semi-detached stock in Southwark 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.

Every Southwark postcode district we draw in, the stock that dominates it and the authority that validates a 1930s semi project there. Southwark fees below are the statutory England rates for 2026, not 1930s semi project estimates.
| Postcode | Area | Dominant stock | What it means for a 1930s semi project |
|---|---|---|---|
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | SE1 straddles a boundary: Bermondsey / Borough / Waterloo addresses fall to Southwark Council or Lambeth Council, so confirm which authority validates the 1930s semi project before submitting SE1 drawings. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | A 1930s semi project in Camberwell may land with Southwark Council or Lambeth Council — SE5 crosses the boundary, and the SE5 policies map decides it street by street. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | A 1930s semi project at an SE15 address in Peckham / Nunhead is determined by Southwark Council under its own Local Plan policies for Peckham / Nunhead. |
| SE16 | Bermondsey / Rotherhithe | Warehouse conversions, Georgian terraces, new-build | SE16 covers Bermondsey / Rotherhithe only; Southwark Council handles the 1930s semi project, and Bermondsey / Rotherhithe case officers apply the SE16 conservation-area map. |
| SE17 | Walworth | Post-war estates, new-build towers | A 1930s semi project at an SE17 address in Walworth is determined by Southwark Council under its own Local Plan policies for Walworth. |
| SE21 | Dulwich Village | Georgian villas, Edwardian villas (Dulwich Estate) | A 1930s semi project in Dulwich Village may land with Southwark Council or Lambeth Council — SE21 crosses the boundary, and the SE21 policies map decides it street by street. |
| SE22 | East Dulwich | Victorian and Edwardian terraces | East Dulwich sits wholly inside SE22, so Southwark Council validates every 1930s semi project submitted from an SE22 address. |
| SE24 | Herne Hill | Victorian villas, Edwardian terraces | A 1930s semi project in Herne Hill may land with Lambeth Council or Southwark Council — SE24 crosses the boundary, and the SE24 policies map decides it street by street. |
Roof pitch, wall build-up and plot depth change every few Southwark streets, and each one changes what a 1930s semi project can achieve at that address.
How designation changes a Southwark 1930s semi project: Southwark Council maintains 43 conservation areas, including Dulwich Village, Peckham Rye, Borough. Inside any of them a Southwark 1930s semi 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. Camberwell Grove sets the tone for Southwark casework.
Article 4 and your Southwark 1930s semi project: Article 4 for HMOs borough-wide; additional Article 4 for office-to-residential in Bermondsey and Elephant & Castle. At a SE1 address that matters twice over, because Southwark Council applies the direction unevenly across Southwark — we read the Southwark policies map for the exact SE1 address before quoting 1930s semi projects.
What Southwark is built from: 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. That mix decides the 1930s semi project route in Southwark more than the postcode does. Our fixed fee for 1930s semi projects in Southwark starts at £840, against £1,750 for the Complete package that carries a Southwark scheme through Southwark Council planning and building regulations together.
