Housing unit

[1][2][3] In common speech in Australia and New Zealand, the word "unit", when referring to housing, usually means an apartment, where a group of apartments is contained in one or more multi-storey buildings (an 'apartment block'), or a villa unit or home unit, where a group of dwellings is in one or more single-storey buildings, usually arranged around a driveway.

Then, a unit is a self-contained suite of rooms, usually of modest scale, which may be attached, semi-detached or detached, within a group of similar dwellings.

Used in the Australian and New Zealand urban planning and development industry, it is also a synonym for dwelling.

A single room unit is more commonly referred to as a studio flat, if the unit has a private bathroom and kitchen, or bedsitter, otherwise known as a single-room occupancy or SRO in North America, if not.

In everyday Canadian English "unit" is used an umbrella term for apartments and condominiums.
