House Extensions in Notting Hill and Notting Hill Gate
For a Notting Hill extension, confirm ownership and access at the rear and whether the proposal affects a shared garden or boundary. A garden setting can influence the design, but consent depends on the property, rights and work proposed.
Start with the property address, the existing layout and the work you want to include. Access, service routes and any relevant approvals are checked against that brief.
Developing your house extensions brief
Start with the scope below, then discuss the building-specific decisions for your Notting Hill property. For the wider service and specification, read our house extensions guide. Fitted storage and vanity cabinetry can be discussed through the bespoke joinery service.
Resolve the extension before planning the finishes
Begin with the existing plan, intended use of the new space and relationship to neighbouring windows, gardens and boundaries. Check the exact property and proposal with the council; permitted development is not a general allowance for flats or listed buildings.
An extension can affect foundations, drainage, structure, insulation and the transition into the existing house. Investigations and structural design should inform the proposed openings and build sequence before the interior specification is fixed.
Check delivery and excavation access, protection of the occupied house and whether the work engages the Party Wall etc. Act. Planning permission, Building Regulations and any party-wall process are separate requirements. Include the existing rooms that need making good in the quotation.
House Extensions in Notting Hill: Questions
Does this page include Notting Hill Gate?
Yes. Use this Notting Hill page for enquiries around Notting Hill Gate too, and provide the full address so the building and proposed scope can be reviewed.
Is an extension included in a house refurbishment quotation?
Only if it is expressly included. Extension feasibility, structure, drainage, approvals and construction should be described separately so the scope can be compared accurately.
Does house extensions in Notting Hill always need planning permission?
No blanket answer applies. Check the proposed work and exact address with the council. Listed-building consent, planning permission and Building Regulations are separate; for a flat, check the lease and any freeholder consent as well.
How should I prepare the project brief?
List the rooms and items to retain, replace or repair, the preferred finish, access arrangements and any known building restrictions. A written scope makes supplier responsibilities, exclusions and changes easier to assess.
Relevant work elsewhere in London
These published examples show the stated service in their named locations. They are not presented as completed projects in Holland Park or Notting Hill.
Check the exact address and proposed work against RBKC planning guidance. Listed-building consent concerns changes affecting a listed building’s special character; conservation-area status and Article 4 directions are different controls. The council’s address-level Article 4 list identifies the properties and directions to check.
For a flat, read the lease and alteration-consent requirements with the freeholder or managing agent. Building Regulations apply separately. Where the proposed work falls within the Party Wall etc. Act, follow that process too. None of these approvals substitutes for another.

The local building context
RBKC’s Ladbroke conservation area, designated in 1969 and appraised in a document adopted on 15 October 2015, centres on the summit of Notting Hill, from which its crescents, terraces and communal gardens fan out along the contours. The appraisal calls the gardens behind the houses, reached directly from them, the estate’s great innovation; the housing is mostly terraced, most often three storeys over a basement and up to five in the largest houses, with villa pairs and triplets in Lansdowne Road, Clarendon Road and Kensington Park Gardens.
Historic England registers the communal gardens together as the Ladbroke Estate, a Grade II park and garden in Notting Hill laid out between 1840 and about 1868, most of them behind the houses and reached from the backs of the houses or through gates from the street. It also lists 10–22 Kensington Park Gardens, a mid-19th-century row of four-storey stuccoed houses facing Ladbroke Square Garden, at Grade II.
East of Pembridge Road and Portobello Road, the Pembridge conservation area, appraised in a document adopted on 30 January 2017, is a quiet residential area of late Georgian and Victorian streets between Westbourne Grove and Notting Hill Gate, from formal terraces in Clanricarde Gardens and Linden Gardens to detached and semi-detached houses on Pembridge Square, Pembridge Place and Dawson Place. Along Notting Hill Gate the appraisal records rows of shops with living accommodation above, and the Local Plan says the town centre was comprehensively redeveloped in the 1950s, at a scale and character different from the conservation areas around it.

Local design and consent context
The Ladbroke appraisal, adopted on 15 October 2015, says the rears facing the communal gardens are often as finely detailed as the fronts and almost all flat, without closet wings. It records harm from large plate-glass units at lower levels, light spilling from over-large windows and glass extensions into the gardens, and hard surfaces, enlarged lightwells and solid fences that can be seen from them.
The Local Plan 2024, adopted by RBKC on 24 July 2024, carries full weight under its adoption statement; the 2015 and 2017 appraisals cite chapters of the earlier plan, so read them with the 2024 policies. Policy CD7 asks extensions backing onto registered communal gardens to preserve views into, from and across the garden, lighting included, and the plan says precedent will not be taken from older, ill-fitting extensions.
Under Policy CD11, new basement space may be a single storey under at most half of each garden, with at least a metre of soil over any part beneath a garden; no further floor may be added where a basement exists, nothing may be dug beneath a listed building, and light wells and roof lights must be discreetly sited and limit light pollution, which the plan also asks of extensions beside the communal gardens.
Access and site planning
RBKC takes highway licence applications only from registered companies, and work waits for its written approval. Book any bay suspension first, with at least 10 full working days’ notice for a resident bay, and quote it on the skip licence form; a skip on the road needs its own licence, renewed while it stays, roll-on, roll-off containers are not allowed and scaffolds need a temporary structure licence. On TfL’s road network data, Notting Hill Gate, Pembridge Road, Ladbroke Grove, Kensington Park Road and Portobello Road are not TfL roads, while the Westway is; for a frontage east of Chepstow Place, check whether Westminster is the council.
