Do you need planning permission for a two-storey rear extension in Westhill?

Planning for a two-storey rear extension in Westhill follows the Scottish householder rules.

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. 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 Westhill like to extend?

Post-war semis and terraces are common around Westhill, and many have room for a single-storey rear extension within Class 1A limits.
