Read through Raised Work Trays for Kitchen or Workroom.. Now do the same thing in your workroom you've just done in your kitchen. If you rarely go there it may not be worth the effort.
If you go there and do light work like building little models, the raised tray just discussed on th web page cited above is still a valid piece of furniture to create.
If you do heavier stuff, you need to start thinking about using either 2-by-4 or 4-by-4 legs, and one or more layers of 1-inch plywood or a 2- to 5-foot piece of 2-by-12 for the top.
I hesitate to advise raising a whole workbench, since certain operations will be made cumbersome on a raised bench (think of power saws, drilling downward, etc.). Additionally, many things one works on are a foot or two tall, so a low bench can be ideal.
I've made a garage work space with a bench 41.5 inches tall and another one about a foot less than that. My utility room has a low bench and one 4 feet high, and there's even a small raised tray that raises the 4-foot bench another 6 inches. The latter is for very close work, building models and such.
In addition to this dynamic bench situation, I also put small carpet pieces on the floor to ward off the foot pain that comes from standing even when a bad spinal disk says not to. These are tucked away underneath a counter in the kitchen, since a piece of carpet on a vinyl floor is a trip-or-slip hazard.
