Open plan
Open plan is the generic term used in architectural and interior design for any floor plan which makes use of large, open spaces and minimizes the use of small, enclosed rooms such as private offices. The term can also refer to landscaping of housing estates, business parks, etc., in which there are no defined property boundaries, such as hedges, fences or walls. In residential design, open plan or open concept (the term used mainly in Canada) describes the elimination of barriers such as walls and doors that traditionally separated distinct functional areas, such as kitchen, living room, and dining room.
