What is the difference between an Aarons Workshop and an Aarons Granny Flat?

An Aarons Workshop has been engineered to meet tough council guidelines and is permissible as a Class 10a (Shed) structure. Our Granny Flats are the same as our Workshops, but with electrical, plaster, wall and ceiling insulation as standard. A Granny Flat requires a Class 1A permit (Habitable Dwelling).
