A foyer is an entrance area or hallway in a building, often serving as a transition space between the outside and the interior. It is commonly found in homes, hotels, theaters, and other public buildings. The foyer may include features like coat racks, seating, or decorative elements, providing a welcoming atmosphere for guests. In residential settings, the foyer can set the tone for the rest of the home, showcasing the owner's style. In larger buildings, such as hotels or theaters, the foyer may serve as a gathering place, often leading to other important areas like lobbies or waiting rooms.
