Do you need planning permission for a kitchen-diner rear extension in Dunbar?
Planning for a kitchen-diner rear extension in Dunbar follows the Scottish householder rules.
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.
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 Dunbar like to extend?
Post-war semis and terraces are common around Dunbar, and many have room for a single-storey rear extension within Class 1A limits.
