Apartment
Self-contained housing unit occupying part of a building
An apartment (North American English), flat (British English, Indian English, South African English) or unit (Australian English), is a self-contained housing unit that occupies part of a building. The housing tenure of apartments also varies considerably, from large-scale public housing, to owner occupancy within what is legally a condominium (strata title or commonhold) or leasehold, to tenants renting from a private landlord. The buildings that contain apartments may be called different things depending on size or country (see below).
