Kitchen extensions in London

Covering London

Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What do you get with a kitchen extension?

We design the room and the kitchen together, so the island, sink and appliances line up with the structure rather than fighting it. You can use your own kitchen supplier or have us supply and fit one. Either way we co-ordinate the trades so the room is finished in one sequence.

Planning and building rules in London

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.

What should I think about before starting?

Worktops are templated after the units are fitted, adding a short gap before completion.
Underfloor heating suits large kitchen-diners with glazed walls.

How does the project run?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

What people ask before starting

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.

Is underfloor heating worth it?

In large open-plan rooms with big glazed doors it frees up wall space and heats evenly. We include it as an option.

Can you visit a house in London to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
