Covering Chiswick
Chiswick sits 6 miles west of London, with Acton 1 miles to the north-west and Barnes 1 miles to the south.
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 does a kitchen extension involve?
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 or permitted development check
- Kitchen fitting, worktop templating and appliances
- Tiling, flooring and decoration-ready finish

Do you need permission for a kitchen extension in Chiswick?
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 can affect a kitchen extension?
- Islands with sinks or hobs need drainage and power routed in the slab.
- Underfloor heating suits large kitchen-diners with glazed walls.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- 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.
