Corners are awkward places to work in -
I use two of mine for storing material vertically - steel bar and angle stock in one corner and aluminum in another -
One other corner has the dust collector (which is plumbed to piping along the two adjacent walls), the hydraulic press and parts washer; the last corner has the drill press table rolled into it and the engine hoist folded up against the wall, plus metal sheet goods bungeed to the wall behind the drill presses.
I wouldn't know what to do with counter space extending to a corner!
