An apartment block refers to a building that is divided into multiple units or apartments, usually for residential purposes. Synonyms for this term include condominiums, flats, complexes, buildings, towers, high-rises, and residences. These terms are often used interchangeably, but there may be slight variations in their meanings. For instance, condominiums typically suggest a more upscale or luxurious dwelling while flats are more common in Europe and may have a slightly different layout. Buildings, towers, and high-rises may refer to larger, multistory structures while residences is a more general term that can encompass a variety of types of housing, not just apartments.
