Covering Hatfield
We work in Hatfield (AL10) and the places around it, including Welwyn Garden City, St Albans and Potters Bar.
Homes in the East of England
The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.
What is included in a kitchen extension in Hatfield?
A kitchen extension is a single-storey extension designed around a new kitchen, usually creating an open-plan kitchen, dining and family space that opens onto the garden. Planning the kitchen layout at the same time as the building means the drains, steels, windows and power end up where the kitchen needs them.
- Combined building and kitchen layout design
- Drainage, gas and electrics planned to the kitchen layout
- Kitchen fitting, worktop templating and appliances

Planning and building rules in Hatfield
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary.
What should I think about before starting?
- Extraction to the outside must be planned before the walls go up.
- Worktops are templated after the units are fitted, adding a short gap before completion.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Kitchen extensions: common questions
Can I use my own kitchen company?
Yes. We work to their drawings and co-ordinate delivery and fitting dates.
Is underfloor heating worth it?
In large open-plan rooms with big glazed doors it frees up wall space and heats evenly. We include it as an option.
