Extension with kitchen: plan a brighter, larger heart of the home
An extension with kitchen combines extra floor area with a new or reworked kitchen layout, often to create an open, connected living space. A professional is typically needed once structure, drainage, services, glazing, or planning constraints affect the design, and the final result is shaped by the site, the existing house, and the level of finish you choose.

Develop a kitchen layout and extension scheme that balances light, storage, circulation, and how the space will actually be used.

— Questions
Frequently asked questions
How much does an extension with kitchen usually cost?
Costs vary widely with size, structure, finishes, glazing, and kitchen specification, so the best starting point is a professional estimate based on your drawings and brief rather than a generic figure.
How long does the project usually take?
A project like this can take several months overall, especially when design, approvals, ordering, and construction are all included. Build time is often shorter than the full process because planning and coordination come first.
Do I need planning permission or other approvals?
Sometimes yes, sometimes no: the answer depends on your local rules, the extension size, the property type, and whether the work affects structure or services. Even when formal permission is not required, building regulations and technical checks usually still apply.
