Do you need planning permission for a kitchen-diner rear extension in Selkirk?
Whether your kitchen-diner rear extension in Selkirk 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.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Selkirk like to extend?
Post-war semis and terraces are common around Selkirk, and many have room for a single-storey rear extension within Class 1A limits.

Kitchen-diner rear extension questions in Selkirk
