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 Retford?
In Retford, a kitchen extension typically costs £2,150–£3,250 per m² including a mid-range kitchen, including VAT at 20% (standard rate). For a typical 22 m² project that is roughly £47,500–£71,500. Building costs in the East Midlands run about 5% below the UK average, and the figures for Retford are adjusted to reflect that. Design, structural calculations and council fees are extra.

The biggest cost drivers are:

- Extension size and roof design
- Glazing and roof lanterns
- Underfloor heating and flooring

Do you need planning permission for a kitchen extension in Retford?
Approvals for a kitchen extension in Retford 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.
We check this for your address before design work starts, so there are no surprises later.

Questions about kitchen extensions in Retford
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.
Who approves a kitchen extension in Retford?
Planning matters in Retford go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
How much does a kitchen extension cost in Retford?
In Retford, a kitchen extension typically costs £2,150–£3,250 per m² including a mid-range kitchen, including VAT at 20% (standard rate). A typical 22 m² project comes to roughly £47,500–£71,500. Your fixed price depends on the survey and drawings.
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.
