Kitchen-diner rear extension in Cumbernauld
An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Cumbernauld and the surrounding area, with one contract from the first survey to building control sign-off.
Cumbernauld is covered from our Lanarkshire round, including G67. For Cumbernauld kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in Cumbernauld?
The planning route for a kitchen-diner rear extension in Cumbernauld is set by Scotland's householder rules and your council.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Cumbernauld like to extend?
Post-war semis and terraces are common around Cumbernauld, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Kitchen-diner rear extension questions in Cumbernauld
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Do I need planning permission for a rear extension in Cumbernauld?

Do you fit the kitchen?
Yes, whether you buy it yourself or we supply it. We take the measurements from the built shell, not the drawings.
Can you match the brick or stone on my Cumbernauld house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
