in Harrow
Harrow is a classically suburban North West London borough, known for Harrow-on-the-Hill's historic hilltop village, its extensive interwar housing estates, and strong family communities. Its well-maintained housing stock represents excellent potential for extensions and improvements.
What You Need to Know About Harrow Planning
Harrow Council's planning policies protect the borough's suburban character and green spaces. The hilltop conservation area at Harrow-on-the-Hill is tightly controlled. Across the rest of the borough, the council is generally supportive of well-designed householder extensions that respect the prevailing suburban character.

Frequently Asked Questions — Harrow Architects
Is my property in a conservation area in Harrow?
Harrow has designated conservation areas including Canons Park Estate Conservation Area, Harrow Park Conservation Area, Little Common Conservation Area, Stanmore and others. Within these areas certain permitted development rights are restricted, so some external alterations that would be permitted elsewhere may need full planning permission supported by design and heritage justification. We confirm your property's designation with London Borough of Harrow at the outset and prepare the documents these applications require.
How long does planning permission take?
Most householder planning applications are determined within the statutory 8-week target; more complex or conservation-area applications can take longer. We manage the whole process and liaise directly with the planning officer on your behalf.
