Between an open space and closed spaces use , a mix between the two was chosen. The integration of spaces with democratic use increases the level of comfort. Thus the center of the space is used as a work area only on certain days, the rest of the time it becomes a space with common use and ensures visibility and easy crossing. The closures are either firm but transparent material boundaries (glass partitions) or flexible (curtain) to the central area, ensuring sound comfort and a clear delimitation when used for work. All spaces are connected by material and color of the floor (carpet) and those of the ceiling (plasterboard or metal grid).
