Camden
A whole-house refurbishment in West Hampstead begins by defining the legal building, ownership evidence, existing structure and proposed work. We establish the planning unit, executed lease and demise where relevant, then survey what previous work actually did to the structure and services before design.
Last updated
The short answer
A refurbishment may be feasible after the planning unit, proposed work, executed lease, retained structure, planning history and mapped controls are checked for the complete application site. Flats and buildings containing flats cannot use Part 1 because of property type, while landlord and public consents remain separate. No consent or programme is guaranteed.

| 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. |

The opening move on a West Hampstead refurbishment is to establish the legal building and proposed work. Property type affects Part 1 availability, while the executed lease and plan establish the demise and any private alteration route. The roof void, rear wall and garden should be checked rather than inferred from how the home appears or is occupied.
Flats and buildings containing flats cannot use Schedule 2 Part 1. That does not make every alteration development. Define the proposed work and planning history for the public route; use the executed lease and plan to determine whether written landlord consent is required and what information supports it.
Reunifying a previously converted house is a distinct project type in West Hampstead, and it is far more than removing a few internal doors. A conversion leaves fingerprints: a second entrance and lobby that now has to be undone, stacked kitchens and bathrooms on upper floors sitting over what will become bedrooms, duplicated consumer units and meters, a stair that was truncated or boxed in, fire-separating ceilings and floor build-ups added between the former flats, and drainage that was routed to serve two households rather than one. Some of that fabric is worth keeping — acoustic floor build-ups often are — and some has to come out. The honest way to plan a reunification is to open up and record before committing, rather than to draw an idealised house and hope the building agrees.
Fire strategy can reshape a whole-house refurbishment. Define the legal building, existing layout and proposed work, then identify the applicable current Building Regulations requirements for escape, compartmentation, doors, linings, alarms and service penetrations. No single fire or stair solution follows from the West Hampstead, terrace, flat or refurbishment label.
Where measured railway noise or another acoustic condition affects a refurbishment, the proposed window performance must be coordinated with any mapped heritage evidence. Heavier frames, thicker or asymmetric glazing and different opening patterns can alter established sightlines. Existing and proposed elevations, window sections and a material schedule should show the actual property and specification; neither railway proximity nor a conservation-area label predetermines the evidence or outcome.
From there the project becomes a matter of sequence and evidence. Survey and opening-up establish the structure, services and fire position before design fixes them. Produce planning information only for the defined public route, Building Regulations information for the applicable technical route, landlord information only where the executed lease requires it, and Party Wall notices only for defined notifiable work. Any occupation, access, common-part or working-hours requirements must come from the project and written obligations rather than an NW6 or tenure label.
Local analysis
Planning, landlord consent and Building Regulations are separate. Define the proposed work for the public-law route; use the executed lease and plan for any landlord-consent route. Record title, demise, retained parts and available alteration history as evidence rather than inferring them from the layout or West Hampstead label.
Previous alterations can be a significant unknown in a refurbishment. Use survey, records and proportionate opening-up to establish fire separation, floor build-ups, wet areas, services, stairs and structure where the proposed work engages them. Record remaining unknowns and allowances in the tender information rather than inferring conditions from West Hampstead or a converted-building label.
Where the address sits inside a conservation area, the West Hampstead frontage is assessed as a set rather than as separate components. The neighbourhood plan describes a homogeneous piece of Victorian and Edwardian domestic architecture, and Camden's West End Green material describes side streets of red-brick houses and mansion blocks, so a window whose frame is heavier, whose sightlines are thicker or whose opening pattern is reversed reads immediately against its neighbours — and against the rest of the terrace. That is the collision to manage on a rail-corridor elevation, where the owner's acoustic case is entirely genuine and the character case is equally real. We resolve it on paper rather than on site: existing and proposed elevations, window sections at a scale that shows the profile, a material schedule, and a clear statement of what is actually visible from the street. We do not promise approval on any of it.

Local planning
Camden is the local planning authority for a West Hampstead application site, but the neighbourhood name and NW6 postcode do not establish a planning unit or mapped designation. Purely internal work may sit outside planning control, while external changes must be defined and checked against planning history, listing, the separate West End Green and South Hampstead maps, and any operative direction. Proximity to a conservation-area boundary is not designation.
Property type changes the permitted-development route. Flats and buildings containing flats cannot use Schedule 2 Part 1; a qualifying dwellinghouse may use a class only if every limitation and condition is met and no planning condition or operative Article 4 direction changes it. Conservation-area status creates class-specific restrictions rather than removing every right. South Hampstead's replacement heritage Article 4 direction was adopted on 9 June 2026 for mapped properties and scheduled operations; West End Green's appraisal recommendation is not an operative direction. We select any certificate or application from the complete site and work without promising consent or timing.
Building Regulations and planning are separate routes. Define the work before identifying the applicable structure, fire, insulation, ventilation, drainage, stairs and waterproofing information. Whether the Act applies depends on the defined work. Section 1 covers qualifying work at the line of junction; section 2 covers specified work to a party wall or structure; section 6 covers excavation within 3 metres only where it goes below adjoining foundations, or within 6 metres where it meets the statutory 45-degree line. If notice is required, an award follows only after dissent or a deemed dispute; valid written consent does not require an award.
For an application site mapped inside West End Green, Camden's appraisal and adopted neighbourhood-plan evidence can inform frontage work. The appraisal was adopted on 28 February 2011, but its topography and character are mapped-area evidence rather than measurements or controls for every West Hampstead property, and its Article 4 recommendation is not an operative direction.
South Hampstead is a separate conservation area with its own map. Camden adopted a replacement heritage Article 4 direction on 9 June 2026 for mapped properties and scheduled operations. Match the complete application site and proposed window, door, roof or frontage work to the current boundary and schedule; being close to the boundary does not itself restrict rights.
