Colney Heath is a village between St Albans and Hatfield, with a common that is a local nature reserve. Homes in Colney Heath include cottages, bungalows and 20th-century family homes.
Post-war houses here often have good-sized gardens and straightforward layouts, which suit single-storey rear extensions and open-plan kitchen-diners. Older cottages need a gentle approach: solid walls, low ceilings and lime mortars all affect how an extension is designed and built. Much of the countryside around Colney Heath 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 Colney Heath can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Colney Heath are decided by St Albans City and District Council. Much of the countryside around Colney Heath 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 Colney Heath 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. Colney Heath is about 8 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Hatfield and London Colney.
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.
Yes, with care. Older cottages often have solid walls, shallow foundations and lime mortar, so the design needs to tie old and new together properly. If the cottage is listed, listed building consent is needed for most changes.
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 Colney Heath 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 Colney Heath are decided by St Albans City and District 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.
