Building and renovation in W11
W11 covers Notting Hill, Notting Hill Gate, Holland Park Avenue, Portobello, Clarendon Cross. Stucco terraces around communal garden squares, mews houses behind the main streets, and converted flats in subdivided terraces. Plot depths vary sharply between the garden-square and Portobello sides.
Planning and consent in W11
Extensive conservation areas and article 4 directions remove permitted development rights across much of W11, so rear extensions, roof alterations and window changes usually need a full application. Communal garden covenants add a second layer of consent.
Access and site logistics
The Gate junction and Portobello market limit kerbside and delivery timing. Garden-square properties need committee agreement for scaffolding, access and storage, with planting protection written into the method statement.
What we are usually asked for here
- Full house renovation of terraced and garden-square properties
- Side-return and rear extensions where article 4 allows
- Dormer and mansard loft conversions on precedented streets
- Mews house remodelling and lower-ground-floor light strategies
We survey the property before pricing, confirm the constraints that apply to your specific address rather than the postcode, and issue a fixed price against a written scope. One site manager runs the trades from first fix to snagging.

Notting Hill's stucco terraces around the communal garden squares are heavily converted, and basement extensions under the front and rear gardens are common in the wider streets.
Garden-level extensions need the waterproofing designed with the structure, not after it: waterproof concrete box, internal Type C cavity drain membrane, perimeter drainage channel, twin-pump sump with backup power, and careful coordination with garden drainage so surface water never loads the new structure.
A Type C cavity drain system in W11 is specified after a survey, designed to BS 8102 for the way you intend to use the room, and installed with the drainage channel, sump and pumps left accessible for maintenance. Read the full basement waterproofing and Type C cavity drain guide, or see how it fits into a basement and cellar conversion.
Waterproofing or damp proofing in W11?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Notting Hill we decide which one the property needs at the survey, and often the answer is an external repair first.
How a W11 quotation works
We visit, find the source of the water, check head height, drainage outfall and any lease or listed-building constraints on your address, then issue a written scope and fixed price covering membrane, channel, sump and pumps and the finished room.
Kitchen and bathroom renovation in W11
Kitchen and bathroom remodelling in Notting Hill and Notting Hill Gate covers strip-out, first-fix plumbing and electrics, any structural work, tiling, fixtures and joinery, managed by one site manager against a detailed written quotation.
Kitchen remodelling in W11
Notting Hill houses commonly place the kitchen on the lower ground floor opening to the garden, so glazing, drainage and waterproofing sit alongside the kitchen design itself.

W11 bathrooms are often spread over four or five storeys; water pressure to the top floor, cylinder capacity and waste routes behind panelled walls are checked at the survey.
Bathroom renovation in London →Every W11 kitchen or bathroom quotation starts with a site survey: we check waste and stack positions, water pressure, extract routes, floor structure and any lease or conservation requirements for your address before pricing.
Garden designer in W11
Notting Hill's terraced and villa gardens, plus some communal garden settings, call for planting and materials that respect the setting and lease terms.
West London gardens are typically long, narrow rear plots behind terraces and semis, often reached only through the house, where levels, drainage near the back wall and privacy planting matter most.
Our garden design and landscaping service covers layout, levels and drainage, planting, terraces and paths, garden lighting and external power, and how materials and plant reach the garden. In W11 that access question matters: The Gate junction and Portobello market limit kerbside and delivery timing. Garden-square properties need committee agreement for scaffolding, access and storage, with planting protection written into the method statement.
Garden designer London →Roofing in W11
W11 stucco terraces often hide shallow roofs and parapet gutters behind front facades, making outlet condition a key part of a roof survey.
Victorian and Edwardian roofs in west London are commonly natural slate or clay tile with valleys, rear-addition flat roofs, chimney stacks and lead flashings that age at different rates.
Roofing work starts with a survey and photographs, then a written scope that states whether repair or replacement is recommended: pitched and flat roofs, leadwork and flashings, guttering and rainwater goods, and the scaffolding the roof needs. Planning, conservation and freeholder requirements for your address are confirmed at survey.
