A foyer room, also known as a foyer or entryway, refers to the area or space immediately inside the entrance of a building or house. It serves as a transitional space between the exterior and the interior of a structure. Foyers are typically found in residential homes, hotels, offices, and other public buildings.

The primary purpose of a foyer is to provide a welcoming and functional space for guests and residents. It serves as a buffer zone, separating the outside environment from the interior living or working areas. Foyers often feature a front door or entrance, and they may include elements such as a coat closet, a shoe rack or shoe storage, a bench or seating area, a console table, and sometimes decorative items like mirrors or artwork.
