Do you need planning permission for a single-storey rear extension in Airdrie?
Here is how the rules in Scotland apply to a single-storey rear extension in Airdrie.
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 Airdrie like to extend?

FAQ
Single-storey rear extension questions in Airdrie
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Airdrie house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.
What postcode areas do you cover around Airdrie?
Including ML6, and the surrounding Lanarkshire area.
Is the site visit in Airdrie free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
