Planning Permission & Building Regulations in Kensington.
Whether a project in Kensington 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.

Kensington: the houses and the planning rules.
Kensington is one of the most consistently protected residential districts in London: white stucco terraces and garden squares south of the High Street, red-brick Queen Anne revival houses around Kensington Court and Phillimore Gardens, and a scatter of mews behind them. Almost every street is in a conservation area and a large share of the houses are listed.
The projects we see here are deep refurbishments of houses that have been divided and reunited over the years, lateral flats in the mansion blocks, and basements under the larger houses where the borough's policy allows. Design quality is scrutinised closely, so drawings and heritage statements have to be right first time.
The Kensington, Kensington Square, De Vere, Edwardes Square and Kensington Palace conservation areas cover almost the whole district.
Royal Borough of Kensington and Chelsea
RBKC decides applications and has some of the most detailed conservation area guidance in London, with Article 4 directions on many streets removing permitted development rights.
Basements
The borough's basement policy limits new basements to a single storey under no more than half the garden, with a construction traffic management plan and an impact assessment.
Listed buildings
Many houses are Grade II listed, so internal alterations need listed building consent alongside planning permission.

Planning Permission & Building Regulations in Kensington: your questions.
Who decides planning applications in Kensington?
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 Kensington?
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.
Which parts of Kensington do you cover?
All of Kensington and W8, including Kensington Church Street, Phillimore Gardens, Kensington Square, Edwardes Square, Victoria Road, Campden Hill Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
