Building and renovation in SW1
SW1 covers Pimlico, Belgravia, Victoria, St James's, Knightsbridge, Westminster. Thomas Cubitt's white stucco terraces in Pimlico and Belgravia, mansion blocks around Victoria, mews houses behind the principal streets and club and office buildings towards St James's.
Planning and consent in SW1
Almost all of SW1 is conservation area and much of it is listed, including interiors. Westminster and Kensington and Chelsea both apply strict basement and external-alteration policies, so consent strategy is decided before design is finalised.
Access and site logistics
Booked loading bays, short working hours, congestion and ULEZ charges, and mansion blocks with their own lift, noise and delivery rules. Access slots are agreed with managing agents before mobilisation.
What we are usually asked for here
- Whole-house and whole-flat renovation in stucco terraces and mansion blocks
- Structural openings and lateral flat combinations with freeholder consent
- Restoration of protected joinery, plasterwork and stucco facades
- Mews house remodelling and lower-ground-floor improvement
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.

Pimlico, Belgravia and Westminster have extensive pavement vaults, service basements under mansion blocks, and lower ground flats in stucco terraces close to the Thames. Ground water levels here are genuinely high and old brick drainage is often still in use.
This is prime Type C territory. Cavity drain membrane to walls and floor, a perimeter drainage channel with rodding access, and a twin-pump sump with battery backup and an alarm — because in SW1 the pumped discharge is often the only route out and the property is frequently occupied year-round.
A Type C cavity drain system in SW1 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 SW1?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Westminster, Pimlico & Belgravia we decide which one the property needs at the survey, and often the answer is an external repair first.
How a SW1 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 SW1
Kitchen and bathroom remodelling in Pimlico and Belgravia 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 SW1
Pimlico, Belgravia and Westminster kitchens are mostly in listed or conservation-area buildings and mansion flats, so lease and listed-building constraints, working hours and extraction routes shape the design from the start.
Kitchen renovation in London →Bathroom remodelling in SW1
SW1 bathrooms are often internal rooms in period buildings; we plan extract routes, pumped waste where needed and floor strengthening for stone before tiling starts, with the freeholder's conditions confirmed first.
Bathroom renovation in London →Every SW1 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 SW1
Pimlico, Belgravia and Westminster outdoor spaces are commonly lightwells, courtyards and roof terraces, often within listed or conservation settings.
Outdoor space in central London is more often a roof terrace, lightwell, courtyard or communal garden than a lawn, so weight, drainage outlets, waterproofing beneath the finish and freeholder consent shape the design.
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 SW1 that access question matters: Booked loading bays, short working hours, congestion and ULEZ charges, and mansion blocks with their own lift, noise and delivery rules. Access slots are agreed with managing agents before mobilisation.
Garden designer London →Roofing in SW1
SW1 stucco and mansion-block roofs often have parapet gutters, lead detailing and shared areas that require freeholder or managing-agent coordination.
Central roofs are often reached only through the building or from a scaffold licensed over a busy pavement, with parapet gutters, lead and plant areas that need careful inspection before any price is fixed.
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.
