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 South Elmsall?
In South Elmsall, a kitchen extension typically costs £2,100–£3,150 per m² including a mid-range kitchen, including VAT at 20% (standard rate). For a typical 22 m² project that is roughly £46,000–£69,500. Prices across Yorkshire and the Humber are typically 7% below the UK average for this kind of work, which is reflected in the range for South Elmsall.

| Size or type | Guide range |
|---|---|
| Smaller project (15 m²) | £31,500–£47,000 |
| Typical project (22 m²) | £46,000–£69,500 |
| Larger project (31 m²) | £65,000–£97,500 |

The biggest cost drivers are:
- Who supplies the kitchen
- Island with sink or hob, which needs services in the floor
- Extension size and roof design
- Kitchen units, worktops and appliances
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a kitchen extension in South Elmsall?
The approval route for South Elmsall is set by planning law in 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Who approves a kitchen extension in South Elmsall?
Planning matters in South Elmsall go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
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.
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.
