Do you need planning permission for a side return extension in Ardrossan?
Here is how the rules in Scotland apply to a side return extension in Ardrossan.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Ardrossan like to extend?
Post-war semis and terraces are common around Ardrossan, and many have room for a single-storey rear extension within Class 1A limits.

Side return extension questions in Ardrossan
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Do you handle building control in Ardrossan?
