Covering Welwyn Garden City
Our coverage around Welwyn Garden City (AL8) also includes Hatfield (3 miles to the south) and Hertford.
Homes in the East of England
Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.
What goes into a kitchen extension?
We design the room and the kitchen together, so the island, sink and appliances line up with the structure rather than fighting it. You can use your own kitchen supplier or have us supply and fit one. Either way we co-ordinate the trades so the room is finished in one sequence.
- Drainage, gas and electrics planned to the kitchen layout
- Kitchen fitting, worktop templating and appliances
- Tiling, flooring and decoration-ready finish

What approvals does a kitchen extension need in England?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
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 can change the price or programme?
- Extraction to the outside must be planned before the walls go up.
- Underfloor heating suits large kitchen-diners with glazed walls.

Kitchen extensions: common questions
How long will we be without a kitchen?
Usually only the final few weeks, when the old kitchen comes out and the wall is opened. We can help set up a temporary kitchen.
Do kitchen extensions need planning permission?
They follow the same rules as any single-storey extension. Many in England are permitted development.
