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

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

PostcodeAreaDominant stockWhat it means for a drawing package
SW9Brixton / StockwellVictorian terraces, post-war estatesBrixton / Stockwell sits wholly inside SW9, so Lambeth Council validates every drawing package submitted from an SW9 address.
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.
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.
SE19Upper Norwood / Crystal PalaceVictorian villas, Edwardian terracesUpper Norwood / Crystal Palace is split at SE19. Either Croydon Council or Lambeth Council can determine a drawing package here, so the SE19 address is checked against both policies maps first.
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.
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.
SE11Kennington / VauxhallGeorgian terraces, post-war estatesSE11 covers Kennington / Vauxhall only; Lambeth Council handles the drawing package, and Kennington / Vauxhall case officers apply the SE11 conservation-area map.

Which Lambeth neighbourhoods suit a drawing package best?

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

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

How designation changes a Lambeth drawing package: Lambeth Council maintains 64 conservation areas, including Brixton Road, Kennington, Brockwell Park. Inside any of them a Lambeth drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Herne Hill sets the tone for Lambeth casework.

What Article 4 removes near Lambeth: Borough-wide Article 4 for HMO conversions; plus office-to-residential restrictions. Before pricing a drawing package we check whether the SE11 address is inside the mapped area, because Lambeth Council draws the Lambeth boundary street by street rather than across the whole of Lambeth.

The building fabric around Lambeth: Victorian terraces in Clapham, Brixton, Herne Hill; Edwardian villas; 1930s and post-war estates in parts of Streatham; Georgian in Kennington. Mix of dense Victorian residential and post-war estate; strong conservation area coverage; generally design-led planning decisions. A drawing package in Lambeth is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Lambeth Council.

Which neighbouring authorities border Lambeth?

What are the chances of approval in Lambeth?

Over the 12 quarters from 2023 Q2 to 2026 Q1, Lambeth decided 1,736 householder planning applications and approved 80.1% of them — 2.9 percentage points below the London average of 83%. That places Lambeth 23rd of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.

Speed matters as much as the odds. Lambeth decided 95.2% of householder applications inside the eight-week statutory period and let 0.3% run past thirteen weeks. A drawing package that is complete and correctly described at validation is the part of that timeline you control; the rest belongs to the council's caseload.
