AAn L-shaped desk creates two distinct surfaces meeting at a right angle — a main desk and a return — where the joint is positioned somewhere along the desk's run. A corner desk is specifically designed to center on a room's corner, with the work surface spanning the corner diagonally or the desk structure designed to nestle into the corner itself. The L-desk creates two distinct work zones; the corner desk creates one work surface centered on the corner. Both use the corner of a room, but in different ways.
