Do you need planning permission for a single-storey rear extension in Annan?
Whether your single-storey rear extension in Annan needs a planning application depends on its size, your house and any local restrictions.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Annan like to extend?
Post-war semis and terraces are common around Annan, and many have room for a single-storey rear extension within Class 1A limits.
