Construction in Chelsea
Chelsea's stucco terraces and mews houses sit almost entirely within conservation areas, so external alterations are heavily controlled and much of the value is added below ground or internally. Basement policies in Kensington and Chelsea are among the strictest in London.
Foxter works throughout Chelsea and the surrounding SW3 postcode district, covering loft conversions, extensions, whole-house renovations, kitchens, bathrooms, basements, roofing, landscaping and commercial fit-out. Every project is run by one site manager with directly employed trades, so you have a single point of accountability from survey to snagging.
Controlled parking zones operate through most of the day, skips need a licence and many streets have no rear access, so materials come in through the house on protected routes.
Before we quote we visit the property, measure it and write a scope of works. That matters more in Chelsea than a per-metre average, because two houses on the same street can have completely different structure, drainage and consent constraints.

Consents and neighbours
We check permitted development rights, conservation area status and article 4 directions against your address before designing, and we serve party wall notices early so a two-month notice period never delays the programme.
Access and logistics
Skip permits, parking suspensions, protected internal routes, dust screens and agreed working hours are planned and priced before we start in Chelsea — not added later as extras.
Price and programme
A fixed price against a written scope, with staged payments tied to milestones. Our instant quotation tool applies a West London area factor so the indicative figure reflects local rates.
