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 Dundee?
In Dundee, a kitchen extension typically costs £2,200–£3,300 per m² including a mid-range kitchen, including VAT at 20% (standard rate). For a typical 22 m² project that is roughly £48,500–£72,500. Building costs in Scotland are close to the UK average, so the figures for Dundee are close to our national guide. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (15 m²) | £33,000–£49,500 |
| Typical project (22 m²) | £48,500–£72,500 |
| Larger project (31 m²) | £68,000–£102,500 |
| Rate per m² | £2,200–£3,300 |
Your quote will depend mainly on:
- Underfloor heating and flooring
- Glazing and roof lanterns
- Extension size and roof design
- Island with sink or hob, which needs services in the floor
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a kitchen extension in Dundee?
The approval route for Dundee is set by planning law in Scotland. In Scotland a single-storey extension is often permitted development (Class 1A): where any part is within 1 metre of a boundary, it can project up to 3 metres from the rear wall of a terraced house or 4 metres on other houses, with eaves no higher than 3 metres, an overall height of 4 metres and no more than half the front or rear garden covered. The rights do not apply in conservation areas or to flats, and a building warrant will usually still be needed before work starts.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
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:
- Kitchen fitting, worktops and splashbacks
- Electrics, lighting plan and sockets
- Flooring and decoration
- Kitchen layout planned alongside the extension design
- Extension structure, roof and glazing
- Building control sign-off
How long does it take?
Build time is typically 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 Dundee
Do I need planning permission for a kitchen extension in Dundee?
In Scotland a single-storey extension is often permitted development (Class 1A): where any part is within 1 metre of a boundary, it can project up to 3 metres from the rear wall of a terraced house or 4 metres on other houses, with eaves no higher than 3 metres, an overall height of 4 metres and no more than half the front or rear garden covered. The rights do not apply in conservation areas or to flats, and a building warrant will usually still be needed before work starts.
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.
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.
Who approves a kitchen extension in Dundee?
Planning matters in Dundee go to the council covering your address, and the work needs a building warrant. We prepare and submit the applications for you.
How long will I be without a kitchen?
Usually 3 to 6 weeks at the end of the job, once the back wall is opened and the new kitchen goes in. We can help set up a temporary kitchen.
