Do you need planning permission for a terraced house rear extension in Irvine?
Whether your terraced house rear extension in Irvine 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.
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 Irvine like to extend?
Post-war semis and terraces are common around Irvine, and many have room for a single-storey rear extension within Class 1A limits.
