This page covers the western part of the borough — West Hampstead, Kilburn, Swiss Cottage and South Hampstead and the streets around them. The stock here is largely Victorian terraces and large purpose-built red-brick mansion blocks, and we prepare drawings across every one of those types for Camden Council.

Whichever route your address falls under, we confirm it free at the measured survey and design to match the western Camden streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.


Every application in West Camden is decided by Camden Council. Householder applications carry a statutory 8-week determination; allow around 12–14 weeks from first call to decision once the measured survey, design and validation are included. We hold a 98% first-time approval rate across Camden.

Every Camden postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Camden fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| NW8 | St John's Wood | Victorian villas, mansion blocks | A drawing package in St John's Wood may land with Westminster City Council or Camden Council — NW8 crosses the boundary, and the NW8 policies map decides it street by street. |
| WC2B | Covent Garden / Holborn | Victorian and Edwardian terraces | WC2B straddles a boundary: Covent Garden / Holborn addresses fall to Westminster City Council or Camden Council, so confirm which authority validates the drawing package before submitting WC2B drawings. |
| N1C | King's Cross | Modern apartments, converted warehouses | N1C covers King's Cross only; Camden Council handles the drawing package, and King's Cross case officers apply the N1C conservation-area map. |
| N6 | Highgate | Georgian villas, Victorian and Edwardian semis | Highgate is split at N6. Either Camden Council or Haringey Council can determine a drawing package here, so the N6 address is checked against both policies maps first. |
| NW1 | Camden Town / Regent's Park | Victorian terraces, mansion blocks | NW1 straddles a boundary: Camden Town / Regent's Park addresses fall to Camden Council or Westminster City Council, so confirm which authority validates the drawing package before submitting NW1 drawings. |
| NW3 | Hampstead / Belsize Park | Georgian and Victorian villas, listed buildings | Hampstead / Belsize Park sits wholly inside NW3, so Camden Council validates every drawing package submitted from an NW3 address. |
| NW5 | Kentish Town / Gospel Oak | Victorian terraces | Kentish Town / Gospel Oak sits wholly inside NW5, so Camden Council validates every drawing package submitted from an NW5 address. |
| NW6 | Kilburn / West Hampstead / Queen's Park | Mansion blocks, post-war flats | NW6 straddles a boundary: Kilburn / West Hampstead / Queen's Park addresses fall to Camden Council or Brent Council, so confirm which authority validates the drawing package before submitting NW6 drawings. |
Roof pitch, wall build-up and plot depth change every few Camden streets, and each one changes what a drawing package can achieve at that address.
