Do you need planning permission for a single-storey rear extension in Cowdenbeath?
The planning route for a single-storey rear extension in Cowdenbeath is set by Scotland's householder rules and your council.
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
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 Cowdenbeath like to extend?
Post-war semis and terraces are common around Cowdenbeath, and many have room for a single-storey rear extension within Class 1A limits.
