Camden
We design rear extensions from the complete West Hampstead application site, planning unit and proposed work. Camden is the local planning authority for a confirmed West Hampstead site, while conservation, Article 4, property type and landlord routes are checked independently rather than inferred from NW6 or station proximity.

The short answer
A rear extension may be feasible after the complete application site, planning unit, property type, mapped controls, history, neighbour relationship and ownership are checked. We prepare the applicable drawings without promising consent, buildability or timing.
Planning at a glance
West Hampstead
| Local planning authority | Camden |
|---|---|
| Postcode district | NW6 |
| Likely approval route | Householder planning application or permitted development, depending on conservation status, listing and property type — confirmed for the exact address before drawings begin |
| Statutory determination time | 8 weeks for most householder applications (13 weeks for major applications) |
| Local planning note | West Hampstead is a neighbourhood label, not proof that an address is inside the Fortune Green and West Hampstead Neighbourhood Area, West End Green Conservation Area, South Hampstead Conservation Area, a heritage Article 4 direction or a listed building. Camden adopted the Camden Local Plan on 3 July 2017. Its proposed replacement was submitted for examination on 3 October 2025; hearings ended on 12 June 2026 and Camden was still publishing examination documents on 3 August 2026, so it was not an adopted replacement on the 12 August 2026 source check. The Fortune Green and West Hampstead Neighbourhood Plan was made on 16 September 2015 and applies only inside its mapped neighbourhood area. The West End Green appraisal was adopted on 28 February 2011, but its recommendation for Article 4 controls is not itself an operative direction; Camden’s current heritage Article 4 page does not list West End Green. Camden adopted a replacement heritage direction on 9 June 2026 for mapped South Hampstead properties and scheduled operations only. Its separate borough-wide basement Article 4 direction took effect on 1 June 2017. Check the exact address, property type, planning history, policy and designation maps, Article 4 schedule, national and local listing records, title and lease, and proposed works before advising. |

Use the complete application site, planning unit, history, proposed work and measured conditions to select the route and drawing scope. Do not infer property type, plot levels, drainage, Party Wall status, landlord requirements or technical evidence from West Hampstead, NW6, station proximity or a building-type label.
We map conservation and Article 4 records for the complete application site. A street name, neighbouring road or nearby boundary is not a substitute for the current property and operation map.
Surveyed sections should record the subject building, garden and neighbour levels where they affect massing and amenity; the area label does not establish those conditions.
For a flat or building containing flats, Part 1 is unavailable because of property type. Read the executed lease for any landlord route and define the external planning work separately; station proximity does not decide either route.
Check the defined boundary, party-structure and excavation work against the Party Wall etc. Act 1996. If notice is required, an award follows only after dissent or a deemed dispute; valid written consent does not require an award. Locate and classify drains or sewers, and check the sewerage undertaker's requirements only where its controlled sewer is affected.
Define the legal building and proposed work before identifying any Building Regulations fire and escape requirements; no protected-route solution follows from the NW6 or open-plan label.
For a qualifying dwellinghouse, test every relevant Part 1 limitation and condition, planning history and operative direction before choosing an LDC or planning application. We do not predict consent or timing.
Camden is the local planning authority only after the complete West Hampstead application site is confirmed. Measured site and neighbour conditions, not comparisons with Hampstead or Highgate, determine the section and amenity evidence.
Related routes include house extension architects, side-return extensions, and building regulations drawings.
A useful first pack is the complete address, application-site plan, rear photos and legal property type. We will not freeze depth until mapped controls, planning history and tenure are clear.
Delivery sequence: confirm the application site and planning unit → map current controls and history → survey measured conditions → define the work → select separate planning, landlord, Party Wall, drainage and Building Regulations routes that apply.
Use the complete application site, measured host and actual rear context to assess materials and bulk; do not infer a design language from West End Lane, Kilburn or NW6.
Test depth from the measured wing lines, classified drainage, neighbour openings, planning history and proposed work rather than a catalogue or postcode assumption.
Local analysis
Survey the host, garden, rear context and neighbouring openings. Use the resulting plans and sections to assess the defined proposal rather than inferring a shared building line or level plot from the area.
Planning amenity, Party Wall procedure, right to light and Building Regulations remain separate decisions even where they use the same measured base.
West End Green and South Hampstead are separate mapped conservation areas. Check the complete application site rather than inferring controls from NW6.
South Hampstead's 9 June 2026 replacement direction applies only to mapped properties and scheduled operations; West End Green's appraisal recommendation is not an operative direction.
Locate and classify the drain or sewer. A build-over agreement is not inferred from a shared or private drain, or from proximity alone; check whether work affects a sewer under the sewerage undertaker's control and whether that undertaker requires an agreement.
Check the defined boundary, party-structure and excavation work against the Act. An award follows only after dissent or a deemed dispute; valid written consent does not require one. Define any fire-safety information from the legal building and proposed work.
This page owns rear house extensions on West Hampstead application sites confirmed in Camden. Property type, mapped controls and the actual work select the public, landlord and technical routes.
Wraparounds and dormers have separate owners when those forms are the real brief.

Local planning
Camden is the local planning authority for a confirmed West Hampstead application site, but the complete address must be mapped rather than inferred from NW6. West End Green and South Hampstead have separate boundaries; South Hampstead's replacement heritage direction was adopted on 9 June 2026 for mapped properties and scheduled operations, while the West End Green appraisal recommendation is not an operative direction.
Assess the proposal from the complete application site, planning unit, measured building and proposed work. Surveyed sections should record actual floor, garden and neighbour levels where they affect design; a West Hampstead or West End Green label does not establish a slope.
Flats and buildings containing flats cannot use Schedule 2 Part 1 because of property type, not station proximity. The public planning route follows the defined external work and history; landlord consent follows the executed lease, and Building Regulations remain separate.
Map the complete application site against the separate West End Green and South Hampstead boundaries; proximity to either boundary is not designation.
Match any operative Article 4 direction to the mapped property and scheduled operation. Conservation status creates class-specific restrictions rather than removing every householder right.
