To me this seems like one of those classic cases of assumed knowledge. It might be unnecessary, undesirable or totally straightforward.
But if you've got specific requirements beyond "I want to buy this garage", best to get legal advice that considers all the requirements.
I'd be careful about what and how you ask councils or building authorities questions in case you need to take out an indemnity against an as yet unknown issue, and need to confirm you haven't made an interested party aware of a right.
