Kitchen-diner rear extensions in Lanarkshire
An open-plan kitchen, dining and family room that opens straight onto the garden. Rear extensions in Lanarkshire: we cover 18 towns including East Kilbride, Hamilton and Meikle Earnock, with design, approvals and the build under one contract.

We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most East Kilbride homes. Post-war semis and terraces are common around Lanarkshire, and many have room for a single-storey rear extension within Class 1A limits.
How much does a kitchen-diner rear extension cost in Lanarkshire?
A kitchen-diner rear extension in Lanarkshire is priced at £1,800–£2,940 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.

Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission in Lanarkshire?
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.

FAQ
Questions people ask
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
Where does the cooker extraction go?
Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.
Do you cover all of Lanarkshire?
We cover 18 towns and districts in Lanarkshire, including East Kilbride, Hamilton and Meikle Earnock.
