About this service
About kitchen extensions
A kitchen extension is a purpose built addition designed specifically to house a new or enlarged kitchen. Unlike general extensions, kitchen extensions are designed with cooking and family life in mind, incorporating space for appliances, worktops, dining, and often bifold or sliding doors to the garden. Kitchen extensions typically start from £35,000 for the structural build, with kitchen fit outs ranging from £10,000 to £50,000+ depending on specification.
Who it's for
Homeowners with small, outdated, or poorly configured kitchens who want a modern kitchen diner space. Kitchen extensions are particularly popular for 1930s-1970s properties where the original kitchen is small and separate.

What homeowners say
What homeowners say about working with us on extensions.
“Shahbaz Ali and the team did a good job at a very high spec. We went through the usual home-building project teething issues but the end result is a beautiful kitchen and dining room extension completed in time. This has not only increased our property value; we really enjoy the extra space. Whoever visits us ask us about the builders who did our home extension and we happily recommend Shahbaz Ali. I would 100% hire him again for any small or large job. Thanks!”

Review on MyBuilder
“We hired Brits Construction services Ltd and I am glad that my decision was 100% right. I hired them around two years ago to do my home extension. They did the job very well however recently there was a plumbing problem and I called Brits, they came and fixed the problem even the warranty was finished a year ago. I am so impressed the services I received hence leaving feedback now. I highly recommend them.”

“Brits provided a very competitive, clear quote for our large renovation/extension job. Fawad and his team communicated very well at all stages of the project, suggesting improvements to the original design and carrying out the job to a very high standard. We were so impressed we have since re-engaged Brits to re-landscape our outside space and renovate extra inside space. The finished product is something we're really proud of and happy with. We would highly recommend to anybody (and have already done so!)”

FAQ
Common Questions
The structural extension typically starts from £35,000 depending on size and complexity. The kitchen itself ranges from around £10,000 for a straightforward supply and fit package to £50,000+ for high-end bespoke layouts and appliances. We can manage the whole project or just the structural build.
We work with trusted kitchen suppliers across London and can manage the entire kitchen installation as part of the project. Alternatively, we can build the extension only and coordinate with your chosen kitchen company.
For many homes, a practical kitchen extension starts around 15 to 20 m². Larger open plan kitchen diners are often 20 to 30 m² and priced accordingly. We help you balance layout, budget, and how you actually use the space.
Yes, but it can be challenging. Many clients set up a temporary kitchen in another room. For larger projects, some choose to move out temporarily. We keep disruption to a minimum with careful planning.
