Purpose-built or converted flats with restricted PD rights. Internal-only alterations dominate.
Modern flat stock in Camden 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 Camden postcode district we draw in, the stock that dominates it and the authority that validates a modern flat project there. Camden fees below are the statutory England rates for 2026, not modern flat project estimates.
| Postcode | Area | Dominant stock | What it means for a modern flat project |
|---|---|---|---|
| WC1B | Bloomsbury | Victorian and Edwardian terraces | WC1B covers Bloomsbury only; Camden Council handles the modern flat project, and Bloomsbury case officers apply the WC1B conservation-area map. |
| WC1H | Bloomsbury / Cartwright Gardens | Victorian and Edwardian terraces | A modern flat project at an WC1H address in Bloomsbury / Cartwright Gardens is determined by Camden Council under its own Local Plan policies for Bloomsbury / Cartwright Gardens. |
| WC1N | Bloomsbury / Russell Square | Victorian and Edwardian terraces | Bloomsbury / Russell Square sits wholly inside WC1N, so Camden Council validates every modern flat project submitted from an WC1N address. |
| WC1R | Holborn | Victorian and Edwardian terraces | Holborn sits wholly inside WC1R, so Camden Council validates every modern flat project submitted from an WC1R address. |
| WC1X | Bloomsbury / Mount Pleasant | Victorian and Edwardian terraces | WC1X straddles a boundary: Bloomsbury / Mount Pleasant addresses fall to Camden Council or Islington Council, so confirm which authority validates the modern flat project before submitting WC1X drawings. |
Roof pitch, wall build-up and plot depth change every few Camden streets, and each one changes what a modern flat project can achieve at that address.
Conservation areas covering Camden: Camden Council runs 40, and Fitzrovia, Hampstead, Primrose Hill are the ones Camden owners meet most. A modern flat project inside a Camden conservation area loses permitted development, so the Camden submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Camden Town a modern flat project is judged on the street elevation first.
Article 4 and your Camden modern flat project: 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 N1C address that matters twice over, because Camden Council applies the direction unevenly across Camden — we read the Camden policies map for the exact N1C address before quoting modern flat projects.
Digging below a Camden property: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Where a modern flat project in Camden involves excavation that is read beside the Party Wall etc. Act 1996, which needs two months notice for a Camden dig within 3 m of a neighbour, and Camden Council expects the N1C ground conditions addressed in the application.
Camden housing stock: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross.
