Planning Permission & Building Regulations in Wealdstone.
Whether a project in Wealdstone 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 Harrow: 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.

Wealdstone: the houses and the planning rules.
Wealdstone grew up around the railway works and the station, and its older streets are Victorian and Edwardian terraces of a type that suit side-return extensions and rear dormers. North of the High Street the housing shifts to 1930s semis with longer gardens, and around the station new apartment buildings have arrived in the last few years.
It is one of the more affordable parts of Harrow, which makes it a district where a well-planned extension or loft adds real value. We do rear and side-return extensions on the terraces, hip-to-gable lofts on the semis, and full refurbishments of houses bought to be improved.
There are no conservation areas in Wealdstone itself; the Harrow Weald and Harrow on the Hill conservation areas lie to the north and south.
London Borough of Harrow
Harrow decides applications. With no conservation area, most rear extensions and lofts fall within permitted development, confirmed by a lawful development certificate.
Terraces
Side-return and rear extensions on the terraces usually proceed under permitted development or prior approval; party wall notices are needed for the shared walls.
Flats
Converted houses and the newer apartment blocks need a licence to alter from the freeholder alongside building regulations.

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.
