Planning Permission in Camden
London Borough in London · Last updated April 2026
Camden is an inner London borough stretching from King's Cross and Bloomsbury in the south to Hampstead and Highgate in the north. The borough has some of London's most architecturally significant neighbourhoods — from Georgian squares in Bloomsbury to large Victorian villas in Hampstead and Belsize Park. If you're planning building work in Camden, this guide covers permitted development rights, application fees, and the local rules you need to know.
Camden has 40 conservation areas covering roughly half the borough, plus 19 Article 4 direction areas and a borough-wide basement Article 4. With nearly 2,000 listed buildings, planning in Camden is tightly controlled. Most homeowners in Camden will need planning permission for works that would be permitted development elsewhere.
Whether you're considering a rear extension, loft conversion, or basement, the rules in Camden depend heavily on your conservation area and Article 4 status. Read on for specific rules, fees, and contacts.

Permitted development in Camden
Permitted development rights in Camden are heavily restricted. Around half the borough is covered by conservation areas, and many of these also have Article 4 directions removing householder PD rights. Outside conservation and Article 4 areas, you can typically build a single-storey rear extension up to 4 metres or add a rear dormer without planning permission. But in Hampstead, Belsize, Bloomsbury, Primrose Hill, Redington/Frognal, and many other areas, you'll need planning permission for almost any visible external change. Crucially, Camden has a borough-wide Article 4 direction for basements (since June 2017) — all basement excavations need planning permission.

What Camden expects from your project
Camden's housing stock spans several centuries. Bloomsbury has formal Georgian squares and terraces in London stock brick with stucco detailing. Hampstead, Belsize Park, and Highgate feature large Victorian and Edwardian villas in red brick and stucco, often set in substantial gardens. Kentish Town and Gospel Oak have redbrick Victorian terraces. The borough also has notable modernist architecture, including the Grade I listed Isokon Flats and the Alexandra Road Estate. Camden's design guidance is set out in the Camden Planning Guidance (CPG) documents — particularly CPG Design, CPG Altering and Extending Your Home, and CPG Basements (adopted 2018, updated 2021). Key principles include respecting the scale and character of the streetscene, using materials that complement the original building, preserving original features in conservation areas, and meeting CPG Amenity standards for daylight, sunlight, and privacy. The Hampstead Neighbourhood Plan (adopted July 2025) adds further locally specific design policies for the Hampstead area.
Local design guidance
- Camden Planning Guidance: Design
Local Plan: Camden Local Plan
The Camden Local Plan was adopted in July 2017. It provides policies for one of the most diverse and pressured boroughs in London, covering areas from the West End to Hampstead. The plan allocates over 16,000 new homes over the plan period. The London Plan (2021) also applies.
Emerging / replacement plan
Camden is preparing a new Local Plan. A Regulation 18 Issues and Options consultation ran in 2022-2023, and a Regulation 19 Pre-Submission Plan consultation took place in 2024.
40 conservation areas
Camden has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
19 Article 4 directions
Camden has applied Article 4 directions to 19 areas, which remove certain permitted development rights in those zones. Use our free checker to see if your property is affected.
Conservation areas in Camden
40 designated conservation areas
Camden's 40 conservation areas cover roughly half the borough, protecting neighbourhoods with exceptional architectural and historic character. Key areas include Bloomsbury (grand Georgian squares and terraces including Bedford Square), Hampstead (historic village character with winding lanes and mixed periods), Belsize Park (large Victorian and Edwardian villas on tree-lined streets), Primrose Hill (Regency and Victorian terraces with protected views), Redington/Frognal (large detached houses in generous gardens), King's Cross/St Pancras (railway heritage and major regeneration), and Fitzjohns/Netherhall (Arts and Crafts and Victorian residential). If your home is in a conservation area, you'll need planning permission for works that would otherwise be permitted development — including rear dormers, cladding, and external alterations. You'll also need consent before removing or pruning significant trees.
Article 4 directions in Camden
19 Article 4 direction areas
Camden has 19 Article 4 direction areas that remove permitted development rights in specific locations. These include heritage/conservation directions in Hampstead, Fitzjohns/Netherhall, Redington/Frognal, Swiss Cottage, Belsize, Primrose Hill, and Dartmouth Park — removing PD rights for works like window replacement, cladding, and front elevation changes. There's also a borough-wide basement Article 4 (since 1 June 2017) requiring planning permission for all basement excavations — Camden limits basements to one storey and 50% of garden area (Local Plan Policy A5). Additionally, Article 4 directions protect employment land by preventing commercial-to-residential conversions in the Central Activities Zone. Always check whether your property is affected before assuming PD rights apply.
Listed buildings in Camden
There are 1,964 listed buildings in Camden. If your property is listed, permitted development rights are significantly restricted. Most external and many internal alterations will require listed building consent, which is separate from planning permission. Always check with Camden's conservation team before starting any work on a listed property.
Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Camden received 2,314 planning applications and decided 1,993 in the year ending September 2025. The approval rate of 88.4% is above the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Camden approved 88.4% of planning applications in the year ending September 2025 — above the national average of 86.9%. The council decided 90% of householder applications within the 8-week target. While the approval rate is healthy, Camden's delegation rate of 90.3% (the proportion decided by officers rather than committee) is lower than many boroughs, meaning more applications go to committee — especially in sensitive conservation areas. If your application follows Camden's design guidance (CPG) and respects the conservation area character, you have a good chance of approval. Consider getting a Lawful Development Certificate if your project is permitted development, or use Camden's pre-application advice service.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Housing delivery in Camden
Housing Delivery Test 2023 measurement | Source: MHCLG
Camden delivered 1,539 homes against a requirement of 2,927 over the three-year measurement period, giving a Housing Delivery Test score of 53%. This is well below the 75% threshold, which triggers the most significant consequence: the “presumption in favour of sustainable development” (also called the “tilted balance”). This means planning applications for housing should be approved unless the harm would significantly and demonstrably outweigh the benefits. For homeowners, this is a strong signal — Camden is under considerable pressure to approve housing, making it one of the more favourable environments for residential planning applications in England.
Lawful Development Certificates in Camden
A Lawful Development Certificate (LDC) is formal confirmation from Camden that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Camden decided 420 householder applications in the year ending september 2025. Their 8-week performance of 90% is below the national average of 93%, so LDC applications may take longer than the 8-week target. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Camden
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Camden's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Camden must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
