Do you need planning permission for a terraced house rear extension in Bonnyrigg?
Here is how the rules in Scotland apply to a terraced house rear extension in Bonnyrigg.
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. 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 Bonnyrigg like to extend?
Post-war semis and terraces are common around Bonnyrigg, and many have room for a single-storey rear extension within Class 1A limits.
