Planning Permission & Building Regulations in Chelsea.
Whether a project in Chelsea needs planning permission, and how difficult that permission is to obtain, depends on the property: whether it is in a conservation area, whether it is listed, whether it is a flat with a freeholder, and whether the council has removed permitted development rights on the street. We check all of this at the first visit and tell you the route before any drawings are made.
We then prepare and submit whatever is needed to the Royal Borough of Kensington and Chelsea: a householder application, a lawful development certificate for permitted development, listed building consent with a heritage statement, or prior approval for a larger extension. Building regulations are handled through an approved inspector or the council's building control, and party wall notices are served where a neighbour's structure is affected.
Because our architects prepare the drawings and our team builds from them, there is no handover between designer, agent and builder. One team is responsible for getting the approval and for building what was approved.

Chelsea: the houses and the planning rules.
Chelsea runs from the red-brick and stucco terraces off the King's Road to the riverside streets around Cheyne Walk. The housing is mostly Victorian, much of it listed, in a dense patchwork of conservation areas policed by the Royal Borough, which is known for strict basement and roof policies.
Our work in Chelsea includes a development of six apartments where we designed, supplied and fitted matching kitchens and wardrobes to the developer's programme. Whether it is one house or a whole building, the same rules apply: careful drawings, early approvals and a build that respects the neighbours.
The Chelsea, Royal Hospital, Cheyne and Chelsea Park/Carlyle conservation areas cover most of the district.
Royal Borough of Kensington and Chelsea
RBKC decides applications. Its basement policy limits basements to a single storey under part of the garden, and it takes a firm line on roof extensions and rear elevations.
Conservation areas
Almost all of Chelsea is within a conservation area. Article 4 directions remove permitted development rights on many streets, so extensions generally need a full application.
Developments and flats
In new and converted buildings, works are coordinated with the freeholder or developer and delivered to a fixed programme.
Approvals for planning permission and building regulations in Chelsea.

Planning Permission & Building Regulations in Chelsea: your questions.
Who decides planning applications in Chelsea?
The Royal Borough of Kensington and Chelsea. Householder applications are normally decided within eight weeks of validation; listed building consent runs to the same timescale unless Historic England is consulted.
Do I need planning permission in Chelsea?
It depends on the property and the proposal. Permitted development covers many rear extensions and lofts, but not in flats, listed buildings or where Article 4 directions apply. We confirm the route at the first visit.
