Radlett is a village on Watling Street with a Thameslink station and a reputation for large family homes. Homes in Radlett include large detached houses and Edwardian and interwar homes.
Victorian and Edwardian homes often suit side-return extensions and rear-dormer loft conversions, and their solid walls need careful detailing where old meets new. 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.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Radlett can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Radlett are decided by Hertsmere Borough Council. Much of the countryside around Radlett 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 Radlett 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. Radlett is about 7 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Shenley and Aldenham.
Yes. Side-return extensions are a popular way to widen the kitchen of a Victorian or Edwardian terrace. Some fall under permitted development, but wraparound designs and homes in conservation areas usually need planning permission, and work near the shared wall usually needs a party wall notice.
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.
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 Radlett 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 Radlett are decided by Hertsmere Borough 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 Radlett, we cover nearby areas such as builders in Shenley, builders in Aldenham, builders in Borehamwood and builders in Bushey. See every place on our areas we cover page.
