Do you need planning permission for a side return extension in Newton Mearns?
The planning route for a side return extension in Newton Mearns is set by Scotland's householder rules and your council.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
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.
