Do you need planning permission for a bungalow rear extension in Cumbernauld?
Planning for a bungalow rear extension in Cumbernauld 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Cumbernauld like to extend?
Post-war semis and terraces are common around Cumbernauld, and many have room for a single-storey rear extension within Class 1A limits.
