Local context

Why Hampstead needs a specialist

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.

Where in Hampstead does a drawing package actually get determined?

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.

How does a drawing package differ street by street across Hampstead?

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

Does Hampstead planning policy restrict a drawing package?

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.
