Planning Permission & Building Regulations in Belsize Park.
Whether a project in Belsize Park 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 London Borough of Camden: 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.

Belsize Park: the houses and the planning rules.
Belsize Park was laid out in the 1850s as a suburb of paired stucco villas with generous gardens, between Hampstead to the north and Primrose Hill to the south. The villas survive in long, leafy streets, many divided into flats, alongside Edwardian mansion blocks and post-war infill.
It is one of the most active refurbishment markets in north London: reuniting houses that were split into flats, refurbishing garden and first-floor maisonettes, and adding rear extensions and basements beneath the villas. Camden's Belsize guidance shapes what is possible on each street.
The Belsize Conservation Area covers most of the district.
London Borough of Camden
Camden decides applications. The Belsize Conservation Area statement sets out expectations for rear extensions, roof works and stucco repair, and Article 4 directions apply on many streets.
Flats and maisonettes
Most properties are leasehold flats, so a licence to alter from the freeholder sits alongside planning and building control.
Basements
Camden's basement policy applies, with a Basement Impact Assessment for any new lower ground floor.

Planning Permission & Building Regulations in Belsize Park: your questions.
Who decides planning applications in Belsize Park?
The London Borough of Camden. 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 Belsize Park?
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.
