Planning Permission & Building Regulations in South Harrow.

Whether a project in South Harrow 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.

South Harrow: the houses and the planning rules.

South Harrow sits below Harrow on the Hill, with the Piccadilly line station at its centre and streets of 1930s semis and terraces running out towards Rayners Lane and Northolt. The older houses climb Roxeth Hill towards the school, and the plots on the flatter streets are generous.

We have built extensions and lofts in Rayners Lane and the surrounding roads for years. The pattern is a rear extension across the full width of the house, a hip-to-gable loft, and often a refurbishment of the kitchen and bathrooms in the same programme.

The Roxeth Hill conservation area covers the slope up to Harrow on the Hill; most other streets are unrestricted.

London Borough of Harrow

Harrow decides applications. Outside the Roxeth Hill conservation area, most single-storey extensions and lofts are permitted development.

Roxeth Hill

Within the conservation area, front alterations and roof changes visible from the street need a full application.

Party walls

Semi-detached and terraced houses share walls with neighbours; party wall notices are served before structural work.

Common questions

Planning Permission & Building Regulations in South Harrow: your questions.

Who decides planning applications in South Harrow?

The London Borough of Harrow. 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 South Harrow?

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 South Harrow do you cover?

All of South Harrow and HA2, including Northolt Road, Roxeth Hill, Shaftesbury Avenue, Eastcote Lane, Alexandra Avenue, Walton Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
