Hemel Hempstead is our home town: the historic Old Town High Street, Boxmoor's Victorian streets and the post-war new town neighbourhoods such as Adeyfield, Bennetts End, Grovehill, Highfield, Warners End and Gadebridge. Homes in Hemel Hempstead include 1950s-60s new town houses, Victorian terraces in Boxmoor and period properties in the Old Town.
Post-war houses here often have good-sized gardens and straightforward layouts, which suit single-storey rear extensions and open-plan kitchen-diners. 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. Older cottages need a gentle approach: solid walls, low ceilings and lime mortars all affect how an extension is designed and built.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Hemel Hempstead can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Hemel Hempstead are decided by Dacorum Borough Council. Parts of Hemel Hempstead are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected.
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 Hemel Hempstead 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. Hemel Hempstead is our home town, and we work right across it, from Boxmoor and the Old Town to Adeyfield, Grovehill and Leverstock Green.
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.
Single-storey rear extensions for a bigger kitchen-diner are the most common, followed by garage conversions and two-storey side extensions where the plot allows. Post-war houses often have regular layouts and simple roofs, which helps keep the structural work straightforward.
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 Hemel Hempstead are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Hemel Hempstead are decided by Dacorum 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 Hemel Hempstead, we cover nearby areas such as builders in Leverstock Green, builders in Kings Langley, builders in St Albans and builders in Great Gaddesden. See every place on our areas we cover page.
