Definition of an outbuilding
An outbuilding is defined by the Residential Design Codes (R-Codes) as “an enclosed non-habitable structure that is detached from any dwelling.”
Outbuildings are also known as sheds, barns and workshops, with varying design, size and construction materials. They may be pre-constructed, transported to and then placed on land, and are capable of being adapted for various uses.
An outbuilding is considered as a Class 10a building under the Building Codes of Australia.
