Do you need planning permission for a two-storey rear extension in Forfar?
The planning route for a two-storey rear extension in Forfar is set by Scotland's householder rules and your council.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
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 Forfar like to extend?
Post-war semis and terraces are common around Forfar, and many have room for a single-storey rear extension within Class 1A limits.

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.
