Abstract: A system of structures for open offices which is versatile, aesthetic and provides easy access to work areas. In one embodiment, a spine of panels offers versatility in locating electrical and communication wires, with outlets located at any height according to each user's specific requirements, eliminating the need for additional supports. Another embodiment allows quick reconfiguration of space through the use of free position elements, permitting the user to modify the design of work areas using panels that allow adjustment between one panel and the next without installing additional elements. A leveling system ensures alignment of the panels.
