What is 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
- Drainage, gas and electrics planned to the kitchen layout
- Steelwork, roof, glazing and insulation

What happens after I enquire?
