Builders and renovators in Chelsea.
Chelsea's townhouses and mews are prime property in the strict sense, and almost every project there involves a conservation area or a listing. CAP designs and builds extensions, lofts, basements and full refurbishments across Chelsea, with one team from planning through to aftercare.


What a project in Chelsea usually involves.
Most of Chelsea lies within conservation areas and many of its buildings are listed, so almost any external change, and many internal ones, need consent from the Royal Borough.
The properties we are asked about in Chelsea are mostly townhouses, mews houses and mansion flats, many of them listed. Around the King's Road, Cheyne Walk and Sloane Square, the character of the street shapes what can be built, and we design to suit it.
Planning applications in Chelsea are decided by the Royal Borough of Kensington and Chelsea. Whatever the project, we check which consents your property needs before recommending any spend on drawings.

Building in Chelsea.
Do you work in Chelsea?
Yes. Chelsea (SW3) is about 5 miles from our base on Mitcham Lane in Streatham, and the work we are asked about there is mostly on townhouses, mews houses and mansion flats, many of them listed.
Do I need planning permission to extend or alter a property in Chelsea?
Almost certainly. Most of Chelsea is within conservation areas and many buildings are listed, so external alterations need planning permission, and a listed building needs listed building consent for internal work too. The Royal Borough's basement policy generally limits a new basement to a single storey under no more than half of the garden. We establish what your property needs before design begins.
Which council decides planning applications in Chelsea?
The Royal Borough of Kensington and Chelsea. Building regulations approval can come from the council's building control team or from a registered building control approver, and we arrange whichever suits the project.
What kind of properties do you work on in Chelsea?
Mostly townhouses, mews houses and mansion flats, many of them listed. Around the King's Road, Cheyne Walk and Sloane Square, the character of the street shapes what can be built, so we look at the property and its surroundings before proposing a design.
