Hampstead (NW3) is, in permitted-development terms, close to a special case. Three conservation areas cover the district — Hampstead, Belsize and Fitzjohns/Netherhall — and Camden has attached a non-immediate Article 4 direction to each of them, on top of the borough-wide Basements direction. The practical effect is that very little in NW3 proceeds under permitted development.

That reshapes what a project looks like here. Basement works need a full application under the Basements direction; the non-immediate Article 4 directions across Hampstead (excluding Frognal Way), Belsize and Fitzjohns/Netherhall strip further rights inside those conservation areas; the village core carries a very high concentration of listed buildings needing listed building consent alongside planning; and because so many of the large Fitzjohns Avenue and Belsize Park villas were long ago converted into flats, a large share of NW3 work is flat alteration — where permitted development rights do not exist in the first place. We establish the designation, listing and tenure position for an NW3 address before drawing to Camden's guidance.

Planning in Hampstead (NW3): what to know before you apply

NW3 is one of the most heavily restricted districts in London for householder work. Camden's Basements Article 4 direction removes permitted development rights for basement schemes, and non-immediate Article 4 directions apply across all three conservation areas — Hampstead (excluding Frognal Way), Belsize and Fitzjohns/Netherhall — removing further rights inside them. The village core has a very high concentration of listed buildings requiring listed building consent, and the widespread conversion of the large villas into flats means many NW3 projects have no permitted development rights regardless of designation. Assume a full application in NW3.

Typical Hampstead housing stock

Georgian houses in the old village core, substantial Victorian red-brick villas along Fitzjohns Avenue and Netherhall Gardens, and large Victorian semi-detached and terraced houses through Belsize Park, much of it converted to flats.

Planning Drawings for Hampstead (NW3) homes: the package and the process

Every planning drawings we prepare for an Hampstead property is drawn to London Borough of Camden’s validation standards and tuned to the NW3 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

What is included in a planning drawing set?

A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.

  • Site location plan (1:1250) and block plan (1:500)
  • Existing floor plans, elevations and sections
  • Proposed floor plans, elevations and sections
  • Roof plans where relevant, with heights and materials annotated
  • A design and access or heritage statement where the borough requires one

How are planning drawings different from building regulations drawings?

Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.

FAQ

Planning Drawings in Hampstead NW3 — FAQs

What scale should London planning drawings be?+
Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.
Do I need an architect to produce planning drawings?+
No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.
How many revisions are included in the fee?+
All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.
Can you draw from my existing plans?+
We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.
Do planning drawings guarantee approval?+
No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.
Do I need planning permission for a rear extension in Camden?+
Frequently, yes. Much of Camden sits within a conservation area or is listed, and near-borough-wide conservation coverage removes permitted development for many external works. On unlisted homes outside a conservation area a rear extension may still qualify, but in Hampstead, Belsize Park and Primrose Hill a full application is usually needed. We confirm the exact constraints for your address before drawing.
What is a Basement Impact Assessment and will I need one in Camden?+
Camden operates one of the most rigorous basement policies in London. Schemes involving a basement or lower-ground extension generally require a Basement Impact Assessment addressing structural stability, drainage and groundwater. If you are considering below-ground space we flag the requirement early and coordinate the assessment so the application is complete when it is submitted.
Can I make changes to a listed building in Camden?+
Often, but listed-building consent is usually required alongside — or instead of — planning permission, and internal as well as external changes can be controlled. Camden has a high density of listed buildings in Hampstead, Bloomsbury and Fitzrovia. We screen listing status for your address first and prepare the heritage-led drawings and justification the council expects.
How long does Camden take to decide an application?+
Camden determines most householder applications within the statutory eight-week period once validated; basement, conservation and listed-building cases can involve additional consultation. We prepare Camden submissions to the council's validation and design standards to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Camden?+
We agree a fixed fee before we start, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Camden approves. A conservation-area rear extension, a basement and a listed-building scheme differ in the evidence required, so we quote once we have seen your project rather than by the hour.
