The present invention relates to furniture and devices and a system for forming working areas within open spaces. More specifically, the present invention relates to furniture, devices and systems that can be used to create individual working areas and offices in an open space with the ability to create privacy similar to an enclosed office without constructing permanent walls and partitions. The invention includes a main support frame/structure supported off the floor which receives and connects to component panels also supported off the floor which function like office walls. The configuration of the resulting compartments is adjustable using different sized panels and by positioning panels and opening in different locations. The system has an open top configuration with an upward lighting system integral to the top support member and inside it to provide upward lighting to the space(s). A privacy door slidably connected to the top support member provides the ability to create privacy like an office with permanent walls.
