Do you need planning permission for a two-storey rear extension in Newton Mearns?
The planning route for a two-storey rear extension in Newton Mearns is set by Scotland's householder rules and your council.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Newton Mearns like to extend?
Newton Mearns has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Two-storey rear extension questions in Newton Mearns
How much does a two-storey rear extension cost in Newton Mearns?
As a guide, £1,710–£2,560 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £51,500–£77,000 at that rate. Your written price follows the survey.
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.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.

Including G77, and the surrounding Glasgow and the Clyde area.
Can you match the brick or stone on my Newton Mearns house?
