What is a kitchen extension?
A kitchen extension is an extension designed around a new kitchen, usually an open-plan kitchen, dining and family space at the back of the house. We build the extension and fit the kitchen as one project, so plumbing, electrics and lighting are planned around the layout from the start.
How much does a kitchen extension cost in Truro?
In Truro, a kitchen extension typically costs £2,300–£3,450 per m² including a mid-range kitchen, including VAT at 20% (standard rate). For a typical 22 m² project that is roughly £50,500–£76,000. Building costs in the South West are close to the UK average, so the figures for Truro are close to our national guide. Design, structural calculations and council fees are extra.

- Underfloor heating and flooring
- Glazing and roof lanterns
- Extension size and roof design
- Kitchen units, worktops and appliances
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a kitchen extension in Truro?
Approvals for a kitchen extension in Truro follow the rules for England. In England a single-storey rear extension is often permitted development: broadly up to 3 metres deep on a semi-detached or terraced house and 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary, and covering no more than half the garden. The larger home extension scheme allows up to 6 or 8 metres if you notify the council first and neighbours have a chance to comment. In conservation areas, National Parks and National Landscapes the larger home extension route, side extensions and cladding are not permitted development. Flats and houses whose rights have been removed need a planning application, and listed buildings need listed building consent.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Drainage and water supply positioned for the sink and appliances
- Flooring and decoration
- Electrics, lighting plan and sockets
- Extension structure, roof and glazing
- Kitchen layout planned alongside the extension design
- Kitchen fitting, worktops and splashbacks
How long does it take?
Allow 11 to 16 weeks on site, including kitchen fitting. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.

Questions about kitchen extensions in Truro
How much does a kitchen extension cost in Truro?
In Truro, a kitchen extension typically costs £2,300–£3,450 per m² including a mid-range kitchen, including VAT at 20% (standard rate). A typical 22 m² project comes to roughly £50,500–£76,000. Your fixed price depends on the survey and drawings.
Should the kitchen be designed before the extension?
Yes. Knowing where the sink, hob and island will go lets us place drains, ducting, sockets and windows correctly during the build.
Is underfloor heating worth it?
In a large open-plan space it frees wall space for units and glazing and gives even heat. It is easiest to fit during the build.
Do you build kitchen extensions in Truro?
Yes. We build kitchen extensions across Truro, including postcodes TR1. Every project starts with a free home visit.
Can I buy my own kitchen?
Yes. You can supply it and we fit it, or we supply it as part of the price. Either way we coordinate deliveries with the build programme.
