Cubicle office designs are primarily divided into two types: freestanding and panel-mounted. Most office cubicle systems begin with a panel-mounted design, with the wall panels serving as the system's foundation. Desks, filing cabinets, and other components are mounted directly onto panel-mounted systems. Separate panels placed around interior components such as desks and filing cabinets are used in freestanding systems. When selecting a Cubicle office design, consider how easy it will be to reconfigure in a new space if you move your office. The arrangement of the cubes is critical: The most common office layouts are standard rows and the "bullpen" style of several employees sharing a larger space, but sometimes offices require a more specialized design.
