Kitchen extensions in East Sussex

Covering East Sussex

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 is 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.

Planning and building rules in East 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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What can change the price or programme?

Islands with sinks or hobs need drainage and power routed in the slab.
Extraction to the outside must be planned before the walls go up.

What happens after I enquire?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

How long will we be without a kitchen?

They follow the same rules as any single-storey extension. Many in England are permitted development.
