A unit is a type of housing. In Australia and New Zealand, the term unit (or sometimes home unit or housing unit) denotes a dwelling within a group (or 'block') of similar dwellings, usually of modest scale, and may be one or more stories high. Units may be attached, semi-detached or detached, and will comprise a self-contained suite of rooms. A single room unit is more commonly referred to as a studio flat or bedsitter, otherwise known as a Single Room Occupancy or SRO in North America. It can be hard to discern precisely what attributes distinguish some multi-dwelling developments as units from those referred to as flats or apartments, though everyday usage suggests there is a class dimension to the term.
