Planning rules for Mayfield
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.
In Scotland you need a building warrant from the council before any work starts, and a completion certificate accepted at the end. The design follows the Scottish Building Standards Technical Handbooks.
