Abstract: A unique space partition arrangement creates either private, three-dimensional work stations or rooms, or a covered entryway for open office space. The module provides workers with the sensation of having their very own private room, even within extremely large, open office plans, thereby alleviating "close work" fatigue. The office module includes two sidewal panels which are positioned in a generally vertical, oppositely facing orientation, and are supported in a spaced apart and freestanding condition. A ceiling has opposite end edges connected with the upper edges of the sidewall panels, and spans the sidewall panels. The office module has a height and girth which are substantially smaller that the respective dimensions of the open office space, so that the office module can be easily transported and placed at any desired location within the room.
