An apartment, flat, or unit is a self-contained housing unit that occupies part of a building, generally on a single storey. There are many names for these overall buildings. The housing tenure of apartments also varies considerably, from large-scale public housing, to owner occupancy within what is legally a condominium, to tenants renting from a private landlord.
