West Hampstead is Victorian and Edwardian villa streets. The streetscape is dominated by edwardian mansion blocks, victorian villas, 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.
