Do you need planning permission for a side return extension in Ayr?
The planning route for a side return extension in Ayr is set by Scotland's householder rules and your council.
In Scotland side extensions are more restricted than rear ones under householder permitted development, and wraparounds generally need planning permission. A building warrant is required before work starts.
Scotland has no Party Wall Act. Work to shared walls is governed by property law and the title deeds, so we agree access and protection with neighbours in writing before work begins.
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 Ayr like to extend?
Post-war semis and terraces are common around Ayr, and many have room for a single-storey rear extension within Class 1A limits.
