Building and renovation in SW3

SW3 covers Chelsea, Brompton, King's Road, Sloane Square, Chelsea Green, Cheyne Walk. Stucco-fronted terraces, red-brick Victorian houses off the King's Road, cottage-scale streets around Chelsea Green, mews properties and riverside houses along Cheyne Walk.

Planning and consent in SW3

Kensington and Chelsea's conservation and basement policies are among the strictest in London: single-storey excavation, limited garden footprint and a construction traffic management plan are the norm. Listing is frequent along the historic riverside streets.

Access and site logistics

Narrow mews, permit-controlled streets, short loading windows and neighbours in close occupation. We agree hoarding, protection and working-hours arrangements with RBKC and adjoining owners before any demolition starts.

What we are usually asked for here

Whole-house renovation and restoration of period Chelsea townhouses
Basement excavation and lower-ground-floor conversion within RBKC policy
Rear extensions, roof terraces and garden reconfiguration
Luxury kitchen, bathroom and bespoke joinery installation

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.

Basement waterproofing in SW3

Chelsea has a dense concentration of converted and newly excavated basements — media rooms, pools, plant and staff accommodation — often under listed or conservation-area houses with strict consent conditions and tight neighbour relations.

Work here is engineered and documented: a waterproofing design to BS 8102 with a named designer, waterproof concrete where the structure is new, an internal Type C cavity drain membrane, zoned channels, duty and standby pumps on separate circuits with backup power, and commissioning records handed over with the warranty.

A Type C cavity drain system in SW3 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 SW3?

Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Chelsea we decide which one the property needs at the survey, and often the answer is an external repair first.

How a SW3 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.

Garden designer in SW3

Chelsea gardens are typically compact and highly visible from neighbouring houses, so stone, evergreen structure and lighting are chosen carefully.

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 SW3 that access question matters: Narrow mews, permit-controlled streets, short loading windows and neighbours in close occupation. We agree hoarding, protection and working-hours arrangements with RBKC and adjoining owners before any demolition starts.

Roofing in SW3

SW3 roofs frequently involve slate, leadwork and parapets on period terraces, with conservation-sensitive materials checked at 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.
