Do you need planning permission for a semi-detached rear extension in East Kilbride?
Whether your semi-detached rear extension in East Kilbride needs a planning application depends on its size, your house and any local restrictions.
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.
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.
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. 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 East Kilbride like to extend?
East Kilbride 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.
