Do you need planning permission for a side return extension in Grangemouth?
Whether your side return extension in Grangemouth needs a planning application depends on its size, your house and any local restrictions.
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. 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 Grangemouth like to extend?
Post-war semis and terraces are common around Grangemouth, and many have room for a single-storey rear extension within Class 1A limits.
