Berkhamsted is a historic market town with the remains of Berkhamsted Castle, a busy High Street and the Grand Union Canal running through the valley. Homes in Berkhamsted include Victorian and Edwardian terraces and villas near the centre and larger detached homes on the valley sides.
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. Larger detached homes here often suit substantial rear or side extensions, garage conversions and kitchen-diner knock-throughs. Parts of Berkhamsted 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 Berkhamsted can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Berkhamsted are decided by Dacorum Borough Council. Parts of Berkhamsted are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Parts of the area around Berkhamsted fall within the Chilterns National Landscape (formerly an Area of Outstanding Natural Beauty). On that land, side extensions, rear extensions of more than one storey and roof extensions such as dormers need planning permission.
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 Berkhamsted is a big decision, so here is what you get with us:
“We have used them twice, exceptional overall - very good after care and communication.”
Yes. Berkhamsted is about 5 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Northchurch and Great Gaddesden.
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.
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 Berkhamsted are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Berkhamsted 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 Berkhamsted, we cover nearby areas such as builders in Northchurch, builders in Great Gaddesden, builders in Bovingdon and builders in Aldbury. See every place on our areas we cover page.
