Anterooms are spaces in a building that serve as a waiting area before entering a larger room or a private space. These rooms often have comfortable seating and may be used as lounges, lobbies, or foyers. There are many synonyms for anterooms, such as vestibules, reception areas, entrance halls, corridors, antechambers, and waiting rooms. Some words that describe the purpose of an anteroom include prelude, preamble, prologue, and introduction. These rooms can convey a sense of formality, elegance, and exclusivity, and their design and decor can set the tone for the rest of the building. Whether it's an office, hotel, or residence, anterooms are an essential part of creating a welcoming and functional space.
