Highgate is village character on the hill, Georgian and Victorian. The streetscape is dominated by georgian villas, victorian and edwardian semis, 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.

Highgate 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 Highgate 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.
Highgate is characterised by village character on the hill, Georgian and Victorian. The dominant stock is Georgian villas, Victorian and Edwardian semis. 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.
Loft conversion drawings in Highgate start at £1,225 for planning + building regs combined.

We quote drawings as a fixed fee — no hourly creep.

Every Highgate postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Highgate fees below are the statutory England rates for 2026, not drawing package estimates.

How designation changes a Highgate drawing package: Camden Council maintains 40 conservation areas, including Camden Town, Fitzrovia, Hampstead. Inside any of them a Highgate drawing package cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Hampstead sets the tone for Highgate casework.
Highgate and Article 4: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. A drawing package planned at a N6 address is checked against that direction first; Camden Council publishes the Highgate extent, and the N6 line rarely follows the Highgate boundary you would expect.
Digging below a Highgate 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 drawing package in Highgate involves excavation that is read beside the Party Wall etc. Act 1996, which needs two months notice for a Highgate dig within 3 m of a neighbour, and Camden Council expects the N6 ground conditions addressed in the application.
The building fabric around Highgate: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross.
