Covering Buckinghamshire
We cover Buckinghamshire, including Milton Keynes, High Wycombe, Aylesbury and Bletchley, and the towns around them.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What is 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
- Steelwork, roof, glazing and insulation

What approvals does a kitchen extension need in England?
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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.
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.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- 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.
