Covering Windsor
We work in Windsor (SL4) and the places around it, including Slough, Egham and Staines.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
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 or permitted development check
- Drainage, gas and electrics planned to the kitchen layout

How is a kitchen extension approved in Windsor?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
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?
- Worktops are templated after the units are fitted, adding a short gap before completion.
- Underfloor heating suits large kitchen-diners with glazed walls.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Kitchen extensions: common questions
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.
