Kensington & Chelsea / Westminster
Start with the complete address, mapped site and proposed work. Notting Hill and W11 do not select a planning authority: relevant land can route to RBKC or Westminster. Identify the council, adopted plan, conservation map, Article 4 position and listing before design. Keep title, lease, garden rights, Building Regulations, Party Wall duties and tree procedures separate.
Last updated
The short answer
Confirm the complete address, application site and whether RBKC or Westminster is responsible. Then map the adopted plan, any live Notting Hill East plan stage, conservation area, Article 4 and listing evidence, and read the actual title or lease. Agree services only after planning, heritage, private consent and technical routes are separated.
Planning at a glance
Notting Hill
| Local planning authority | Royal Borough of Kensington and Chelsea or Westminster City Council — confirm the exact address |
|---|---|
| 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 | Notting Hill is a neighbourhood description, not a local-authority or conservation-area boundary. Confirm the complete address and application site before using council material. For an RBKC site, use the Local Plan 2024, the current policies map and the mapped conservation area, Article 4, listing, tree and planning-history records. For a Westminster site, use the City Plan 2019–2040 (2026), Westminster mapping and the applicable conservation, Article 4, listing, tree and planning-history records. The submitted Notting Hill East Neighbourhood Plan completed independent examination in May 2026 and was recommended for referendum, but Westminster’s checked list of made neighbourhood plans does not include it; do not describe it as adopted or made. RBKC’s basement Article 4 direction took effect on 28 April 2016 for the defined basement rights of single dwellinghouses across that borough; Westminster’s separate city-wide basement direction took effect on 31 July 2016. Planning permission, listed-building consent, landlord consent, Building Regulations or BSR approval, Party Wall procedures and tree controls remain separate. |

A useful brief separates place identity from legal control. Begin with a verified record of council, planning unit, conservation area, Article 4 direction, listing, title, lease and history. Where the confirmed authority is RBKC, we act as conservation area architects in Kensington and Chelsea, building the heritage case from the appraisal mapped to that site rather than the place-name. Measure the boundaries, levels, neighbours, trees, shared fabric and access relevant to the work.
Programme statutory and private tracks independently. Planning does not grant listed-building, landlord or Building Regulations approval. Planning drawings explain scale, use and context; heritage, lease and technical information answer their own tests. State stages, consultants, applications, fees and exclusions.
Local analysis
Do not use the Notting Hill name, W11 or a nearby landmark to choose the council. Plot the complete address and application boundary, confirm the authority, then open that authority’s adopted plan and policies map. This prevents an RBKC policy from being applied to Westminster land, or emerging Westminster work from being treated as current policy. Record the result in the brief so every later drawing and statement uses the same jurisdiction.
Stucco, brick, a garden outlook or a period terrace does not identify the applicable designation. Match the site to the current conservation map, select the relevant appraisal and check whether an Article 4 direction affects that property and proposed operation. An address outside a conservation area still needs normal planning and design review; an address inside one is not automatically barred from alteration. The evidence changes the assessment, not the ownership label.
Local services
An initial review should list the address, authority, planning unit, designation, Article 4 position, listing search, title, lease, planning history and known building constraints. It should also identify missing surveys and specialist advice. That is more useful than sketching a maximum extension before the legal and physical site is understood, because it shows which questions can be answered now and which remain conditional.
Existing and proposed plans, elevations and sections should share one measured base. Add site and roof information where visibility, levels or neighbours matter, and use heritage material only where a mapped designation or listed status engages it. The written case should cite the current authority and plan, explain the proposal’s effect and avoid borrowed precedent that does not share the same boundary, building type or planning history.
Local evidence
The survey should capture the building, boundaries, levels, relevant trees, neighbouring openings, rear and roof context, access and visible shared fabric. Photographs and planning history help distinguish a genuine local pattern from a superficially similar precedent. For lower-ground work, identify drainage, structure, ground and water questions requiring specialist input. Evidence should be proportionate to the proposal, not a generic list attached to every address.
Obtain current title information and the executed lease where applicable. Mark the demise, retained parts, garden or roof rights, common access, services and alteration covenant against the measured survey. This exposes a boundary or ownership conflict while options are still flexible. It also prevents planning language about amenity or character from being mistaken for permission to build on land or fabric controlled by someone else.
Local process
Plot the address and site, identify RBKC or Westminster, record the adopted plan and neighbourhood-plan stage, and check conservation, Article 4 and listing sources. Gather title, lease, management rules and planning history. Issue a short constraints schedule showing confirmed facts, absent documents and conditional questions. That schedule sets the survey and consultant brief without implying that every Notting Hill property carries the same risks.
Measure the property and the context needed for the work, then test proportionate options against planning, heritage, ownership and technical constraints. Confirm which drawings and supporting evidence each decision-maker needs. Hold a route review before fixing the preferred scheme so the client understands what depends on council permission, listed status, landlord agreement, Building Regulations, Party Wall procedure, tree controls or further investigation.
Develop one drawing base while keeping each approval distinct. Incorporate consultant information, answer queries against the evidence and update the risk schedule. Westminster’s 2026 Code of Construction Practice applies to new sites from 1 June 2026 and existing sites from 1 September 2026 where its scope engages them. Before tender, state outstanding approvals, responsibilities and exclusions; record construction changes that could affect compliance.

Local planning
Use the complete address and mapped application site to establish whether the relevant authority is RBKC or Westminster. Neither “Notting Hill” nor W11 is a jurisdiction test.
RBKC adopted its current Local Plan 2024 on 24 July 2024. Use that plan and the current policies map for an RBKC site.
Westminster adopted its City Plan 2019–2040 (2026) on 21 January 2026. Full New City Plan work announced in July 2026 remains emerging.
The submitted Notting Hill East plan completed independent examination in May 2026 and was recommended for referendum, but Westminster’s made-plan list does not include it. Do not call it adopted or made.
The London Plan 2021 remains adopted and current. Draft London Plan consultation from 16 July to 15 October 2026 concerns an emerging plan, not adopted policy.
Map conservation separately. RBKC records several distinct areas around the wider place-name; Westminster-side land can engage Westbourne or another mapped context.
Schedule 2 Part 1 rights are for qualifying dwellinghouses and remain subject to every class, limitation and condition. Flats and buildings containing flats do not use them.
RBKC’s basement Article 4 direction took effect on 28 April 2016 for defined basement rights of single dwellinghouses across that borough; Westminster’s separate city-wide basement direction took effect on 31 July 2016. Heritage directions are separate and operation-specific.
RBKC’s Basements SPD is 2016 guidance whose landing page still refers to the superseded Local Plan 2019. Pair it with the Local Plan 2024; do not call it current adopted policy.
Lower-ground feasibility also requires history and site evidence for structure, ground, water, trees, access and neighbours. A nearby excavation proves none of those points.
Planning, listed-building and landlord consent, Building Regulations or BSR approval, Party Wall duties and tree procedures remain independent. For building work, the headline higher-risk-building height test is at least seven storeys or 18 metres, with the applicable use test; a residential building also needs at least two residential units. Check the statutory method and exclusions.
A service-specific child may be scoped to a verified authority and project route. Recheck the address before using its guidance across the wider place-name.
No neighbouring approval, conservation description or pre-application discussion guarantees permission.
Notting Hill is not one conservation designation. RBKC mapping can identify Ladbroke, Norland, Pembridge, Colville, Oxford Gardens, Kensington Palace or another distinct area.
Westminster has separate mapping. A Westminster address described as Notting Hill can require the Westbourne record or another designation, not an RBKC appraisal.
Conservation designation does not prohibit every alteration. Read the applicable appraisal, current policy, history and any operation-specific Article 4 direction against the measured proposal.
Heritage Article 4 coverage is property- and operation-specific. A direction for one external change does not automatically decide another operation or address.
A private or communal garden relationship is site-specific. Confirm title, lease, management rules, outlook and footprint before describing private or design consequences.
Older appraisals can document character, but superseded policy references are not substitutes for the current plan and live map.
Search the National Heritage List and council records by address. A nearby entry, terrace description or conservation-area location does not establish listing.
Listed-building consent can be required for work affecting character as a building of special architectural or historic interest; internal fabric can matter.
Listing, planning, title and lease answer different questions. Confirm the affected fabric and consent route before design.
