What goes into a double-storey extension?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

Do you need permission for a double-storey extension in Coatbridge?

Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.

Two-storey extensions in Scotland almost always need planning permission, and a building warrant must be granted before work starts.

What can affect a double-storey extension?

Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
The new roof is tied into the old one, so roof tiles and ridge details need to match.
