Harrow Weald is a leafy suburb north of Harrow at the edge of the Green Belt, near Harrow Weald Common. Homes in Harrow Weald include 1930s semis and detached houses with some Victorian properties.
1930s semi-detached houses are classic candidates for hip-to-gable loft conversions and wraparound rear extensions. Larger detached homes here often suit substantial rear or side extensions, garage conversions and kitchen-diner knock-throughs. Much of the countryside around Harrow Weald is Metropolitan Green Belt, where extensions that are disproportionate to the original house are unlikely to be approved.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Harrow Weald can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Harrow Weald are decided by Harrow Council. Much of the countryside around Harrow Weald is Metropolitan Green Belt. Permitted development still applies to most houses, but applications for larger extensions are judged on whether they are disproportionate to the original building.
Whatever the planning position, extensions and loft and garage conversions need Building Regulations approval, which covers structure, fire safety, insulation and ventilation. Our guide to planning permission for house extensions explains the limits, and the Planning Portal guide to extensions has interactive examples.

Choosing builders in Harrow Weald is a big decision, so here is what you get with us:
“They kept on time and on budget. It was a downstairs kitchen bathroom extension so obviously disruptive but made it as easy as possible.”
Yes. Harrow Weald is about 11 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Hatch End and Stanmore.
Usually, yes. Hip-to-gable and rear dormer conversions are common on 1930s semis and are often permitted development within the 50 cubic metre allowance, unless the house is in a conservation area. Building Regulations approval is always needed.
Yes. A detached house can usually extend 4 metres to the rear under permitted development, or up to 8 metres with prior approval, and we also build double-storey extensions with planning permission.
Not always. Many single-storey rear extensions are allowed under permitted development, within limits such as 3 metres deep for an attached house (4 metres for a detached one) and 4 metres high. Much of the countryside around Harrow Weald is Metropolitan Green Belt. Permitted development still applies to most houses, but applications for larger extensions are judged on whether they are disproportionate to the original building. Applications in Harrow Weald are decided by Harrow Council. A Lawful Development Certificate gives written confirmation if you're unsure.
Every extension is priced individually, so we give a free, itemised written quote after visiting your home. The main things that move the price are size, the number of storeys, foundations and ground conditions, structural steelwork, glazing, and the kitchen or bathroom fittings you choose.
Councils aim to decide householder planning applications within 8 weeks, and Building Regulations approval can run alongside. Build time depends on size and specification, so we set out a written programme with your quote.
Yes. Our team covers carpentry, bricklaying, roofing, plastering, painting and decorating, and kitchen fitting, and we manage the project from design to completion, so you deal with one firm rather than several contractors.
As well as Harrow Weald, we cover nearby areas such as builders in Hatch End, builders in Stanmore, builders in Bushey Heath and builders in Pinner. See every place on our areas we cover page.
