Do you need planning permission for a side return extension in Nairn?
Here is how the rules in Scotland apply to a side return extension in Nairn.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
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 Nairn like to extend?
Traditional stone houses sit alongside modern bungalows and timber-frame homes around Nairn. A lighter, contrasting addition at the back often suits older stone houses better than trying to copy the walling.
