Start with use, site and certainty
Outbuildings can look simple, but planning risk often depends on where the building sits, how it will be used, how large it is and whether other limits or designations apply.
Checks to make
Check whether the building is incidental to the main house, where it sits in relation to the principal elevation, how much curtilage is already covered, whether the site is in a designated area and whether a lawful development certificate would remove doubt.
