Hampstead is affluent, listed Georgian and Victorian villas. The streetscape is dominated by georgian and victorian villas, listed buildings, which means design decisions — roofscape, rear glazing, side returns, mansards — must respect the period rhythm of the row. Camden planning (Camden Council) decides applications here. Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas.

Hampstead sits within Camden, so applications are decided by Camden Council. Most single-storey rear extensions and side-returns on terraced or semi-detached homes in Hampstead fall under Permitted Development — up to 3m deep (attached) or 4m (detached), under 4m high. Flats, listed buildings and conservation areas always require full planning. Article 4 status here: Yes. We check eligibility free at the site visit.
Hampstead is characterised by affluent, listed Georgian and Victorian villas. The dominant stock is Georgian and Victorian villas, listed buildings. We've drawn extensions and lofts for every period represented here — Victorian rear additions, Edwardian side returns, 1930s wrap-arounds, and contemporary infill where the streetscape allows.
Camden Council statutory determination is 8 weeks for householder applications. Validation typically adds 1–2 weeks. From your first call to a decision, expect 12–14 weeks total: 1 week measured survey, 2 weeks design, 1–2 weeks validation, 8 weeks determination. We've achieved a 98% first-time approval rate across Camden.

Every Hampstead postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Hampstead fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| 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. |

| NW1 | Primrose Hill | Victorian and Edwardian terraces | Neighbouring Primrose Hill, where drawing package work is handled by the same Camden Council case officers. |

Conservation areas covering Hampstead: Camden Council runs 40, and Hampstead, Primrose Hill, Bloomsbury are the ones Hampstead owners meet most. A drawing package inside a Hampstead conservation area loses permitted development, so the Hampstead submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Fitzrovia a drawing package is judged on the street elevation first.
Article 4 and your Hampstead drawing package: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. At a NW3 address that matters twice over, because Camden Council applies the direction unevenly across Hampstead — we read the Hampstead policies map for the exact NW3 address before quoting architectural drawings.
Hampstead below-ground policy: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Any drawing package in Hampstead that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Camden Council will want the NW3 ground and groundwater position set out.
Hampstead housing stock: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross. Creative, affluent in Hampstead and Primrose Hill; dense mixed-use around Camden Town and Kings Cross; academic character in Bloomsbury. Read that before choosing a drawing package route in Hampstead — construction, not postcode, sets what is achievable. Architectural drawings in Hampstead start at £840 on a fixed fee, or £1,750 for the Complete package covering both Camden Council submissions.
