Covering West Sussex
Our kitchen extensions service in West Sussex covers Crawley, Worthing, Bognor Regis and Littlehampton and more.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What do you get with a kitchen extension?
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
- Planning or permitted development check
- Kitchen fitting, worktop templating and appliances

Do you need permission for a kitchen extension in West Sussex?
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 can affect a kitchen extension?
- Extraction to the outside must be planned before the walls go up.
- Underfloor heating suits large kitchen-diners with glazed walls.
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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
