These components: are pre-finished; can be stored and shipped knock-down (k-d); and are secured directly to each other with simple tools to provide the completed and assembled work station. Additional full or half-size side panels can be added to the basic desk to form vertical supports for additional work surfaces, to provide other work stations such as a desk and secretarial run-off combined, and/or a desk, run-off, and return combined. Individual drawers and/or open, shelved, door or drawer cabinets can thereafter be secured beneath the work surfaces and between the side panels of the return, run-off, and/or desk to provide the desired form of storage space, which can include, conventional type desk pedestals.
