What goes into a kitchen extension?
A kitchen extension is a single-storey extension designed around a new kitchen, usually creating an open-plan kitchen, dining and family space that opens onto the garden. Planning the kitchen layout at the same time as the building means the drains, steels, windows and power end up where the kitchen needs them.
- Planning and building regulations checks under Welsh rules
- Planning or permitted development check
- Steelwork, roof, glazing and insulation

Planning and building rules in Gwynedd and Anglesey
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Wales has its own permitted development rules, set by the Welsh Government. Small single-storey rear extensions can often go ahead without an application, but the limits differ from England's and there is no larger-extension prior approval route, so we check the current Welsh rules for your house before drawings are finalised.
What should Gwynedd and Anglesey homeowners check first?
- Worktops are templated after the units are fitted, adding a short gap before completion.
- Underfloor heating suits large kitchen-diners with glazed walls.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
Kitchen extensions: common questions
Can I use my own kitchen company?
Yes. We work to their drawings and co-ordinate delivery and fitting dates.
How long will we be without a kitchen?
Usually only the final few weeks, when the old kitchen comes out and the wall is opened. We can help set up a temporary kitchen.
