Apartment building

An apartment (in American English) or flat (in British English) is a self-contained housing unit (a type of residential real estate) that occupies only part of a building. Such a building may be called an apartment building, apartment house (in American English), block of flats, tower block, high-rise or, occasionally mansion block (in British English), especially if it consists of many apartments for rent. In Scotland it is often called a tenement, which has a pejorative connotation elsewhere. Apartments may be owned by an owner/occupier by leasehold tenure or rented by tenants (two types of housing tenure). ... In some countries the word unit is a more general term referring to both apartments and rental business suites. ... Some buildings can be characterized as mixed use buildings, meaning part of the building is for commercial, business, or office use, usually on the first floor or first couple of floors, and there are one or more apartments in the rest of the building, usually on the upper floors.
