Covering Cornwall
Our coverage across Cornwall includes Redruth, Falmouth, St Austell and Truro.
Because Cornwall covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
What is included in a kitchen extension in Cornwall?
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.
- Planning or permitted development check
- Drainage, gas and electrics planned to the kitchen layout
- Kitchen fitting, worktop templating and appliances
What will a kitchen extension cost?
Indicative costs for kitchen extensions. London and the South East usually sit towards the top of each range.
| Kitchen extensions | Guide price incl. VAT |
|---|---|
| Extension build | £2,600 to £4,000 per m² |
| Kitchen supply and fit, mid-range | £10,000 to £20,000 |
| Kitchen supply and fit, high-end | £20,000 to £40,000 |
How is a kitchen extension approved in Cornwall?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 affect a kitchen extension?
- Islands with sinks or hobs need drainage and power routed in the slab.
- Underfloor heating suits large kitchen-diners with glazed walls.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Kitchen extensions: common questions
How much does a kitchen extension cost?
The build is usually £2,600 to £4,000 per square metre including VAT, and the kitchen adds roughly £10,000 to £40,000 depending on the units, worktops and appliances.
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.
Who deals with the council for a project in Cornwall?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
