Hatfield is home to Hatfield House, the historic streets of Old Hatfield and the University of Hertfordshire, alongside its post-war new town. Homes in Hatfield include listed buildings in Old Hatfield, post-war new town housing and developments on the former aerodrome.
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. On newer estates, permitted development rights are sometimes removed by a planning condition, so we check before designing an extension or garage conversion.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Hatfield can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Hatfield are decided by Welwyn Hatfield Borough Council. Parts of Hatfield 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.
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 Hatfield is a big decision, so here is what you get with us:
“Always on time, very friendly, very tidy and exceptional workmanship. Made the whole process a lot less stressful.”
Yes. Hatfield is about 10 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Colney Heath and Welwyn Garden City.
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. Parts of Hatfield are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Hatfield are decided by Welwyn Hatfield 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 Hatfield, we cover nearby areas such as builders in Colney Heath, builders in Welwyn Garden City, builders in North Mymms and builders in St Albans. See every place on our areas we cover page.
