Kitchen Extensions in London
Most extensions we build end up as a kitchen-diner. We build the extension and fit the kitchen as one job: one programme, one quote and one team responsible from foundations to worktops.

Questions we're often asked
Can I supply my own kitchen?
Yes. We can fit a kitchen you have bought, or design and make one for you.
How long will we be without a kitchen?
Usually only the last few weeks, as the old kitchen stays in use while the extension is built.
