Do you need planning permission in Edinburgh and the Lothians?

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.

In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.

Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
