Planning drawings for Hampstead start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Camden Council. On NW3's grand victorian and georgian villas, mansion blocks, the recurring questions are roof additions, rear and side-return extensions, and alterations within Hampstead, Belsize, Fitzjohns / Netherhall, Swiss Cottage. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Hampstead, Belsize Park, Swiss Cottage, Frognal.
A fixed-fee, end-to-end service — measured survey, scaled drawings, Design & Access Statement where required, Planning Portal submission, and full agent liaison until the council's decision.
Across Hampstead, Belsize Park, Swiss Cottage, Frognal in NW3, the dominant property is grand victorian and georgian villas, mansion blocks and large semi-detached houses across hampstead and belsize park. That stock shapes what planning permission drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Camden Council judges each on design quality and neighbour impact. We survey the specific Hampstead property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the NW3 streetscape.

Listed, conservation or complex sites.
Among the most controlled in London. The Hampstead and Belsize conservation areas, with many listed villas, mean full planning — and often Listed Building Consent — for almost any external change, with detailed scrutiny of brick, render, sashes and roofscape. We design to that standard and produce the Heritage Statement Camden requires.
Sometimes, on the larger plots, but Camden's basement policy is strict — single-storey, with a Basement Impact Assessment covering structure, hydrology and trees. The Frognal and Belsize Park Gardens villas can suit it. We draw the scheme and coordinate the engineering and arboricultural reports.
They can be. The Fitzjohn's Avenue and Belsize mansion blocks are often within conservation areas and have freeholder controls as well as planning, so internal reconfiguration and any external change need both consents. We produce drawings that satisfy the freeholder and Camden, and handle Party Wall matters between flats.
It shows the area is well-understood — we've worked across Belsize Park and Hampstead and know how Camden's conservation officers assess these streets. That experience shapes how we detail and justify a scheme so it reads as part of the original villa, which matters on NW3's heavily designated roads.
Our fixed fee for planning permission drawings in Hampstead starts at £840 — no hourly billing. With Hampstead property at around £900,000 for a flat and £3m+ for a Hampstead villa, the professional drawing fee is a small fraction of the value the work adds to NW3's grand victorian and georgian villas, mansion blocks. Camden Council charges its own statutory application fee on top (currently £258 for a householder planning application, £578 for a full application). We quote the drawings as one fixed price and the free site survey covers every NW3 address.
For a NW3 project across Hampstead, Belsize Park, Swiss Cottage, Frognal, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Camden Council (8 weeks for a householder application). We carry the Hampstead application through every officer query to the decision.
Hampstead (NW3) sits primarily in Camden, so applications are decided by Camden Council. Article 4 in force in the borough: Yes. Conservation areas within NW3 include Hampstead, Belsize, Fitzjohns / Netherhall, Swiss Cottage, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind planning permission drawings in Hampstead — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Camden Council Building Control or an approved inspector. On NW3's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. With Hampstead (NW3) property at around £900,000 for a flat and £3m+ for a Hampstead villa, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £840 keeps the professional cost predictable. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on NW3 homes.
