Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
What do you get with a kitchen extension?
A kitchen extension is a single-storey extension designed around a new kitchen, usually creating an open-plan kitchen, dining and family space that opens onto the garden. Planning the kitchen layout at the same time as the building means the drains, steels, windows and power end up where the kitchen needs them.
- Combined building and kitchen layout design
- Kitchen fitting, worktop templating and appliances
- Tiling, flooring and decoration-ready finish
What will a kitchen extension cost?
Typical ranges for kitchen extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| 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 |
What approvals does a kitchen extension need in England?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
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 should I think about before starting?
- Extraction to the outside must be planned before the walls go up.
- Worktops are templated after the units are fitted, adding a short gap before completion.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
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.
How long will we be without a kitchen?
Usually only the final few weeks, when the old kitchen comes out and the wall is opened. We can help set up a temporary kitchen.
