Stanmore is at the end of the Jubilee line, with Stanmore Common, Bentley Priory and the Royal National Orthopaedic Hospital nearby. Homes in Stanmore include 1930s detached houses and large family homes.
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. Parts of Stanmore are covered by a conservation area, where materials, windows and roof lines need extra care and some work needs consent.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Stanmore can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Stanmore are decided by Harrow Council. Parts of Stanmore are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Much of the countryside around Stanmore 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.
Every project starts with a free visit and a written quote; see how an extension project with us works, step by step.
Choosing builders in Stanmore 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. Stanmore is about 11 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Harrow Weald and Little 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. Parts of Stanmore are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Stanmore 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 Stanmore, we cover nearby areas such as builders in Harrow Weald, builders in Little Stanmore, builders in Stone Grove and builders in Bushey Heath. See every place on our areas we cover page.
