Apartment plan

An apartment (American English), or flat (British English, Indian English), is a self-contained housing unit (a type of residential real estate) that occupies only part of a building, generally on a single story. There are many names for these overall buildings, see below. 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), to tenants renting from a private landlord (see leasehold estate).
