I made a wall unit out of upper kitchen cabinets that I got at Ikea. Upper cabinets are fairly shallow. I set the bottom that was at floor level on a strip of 1x2 so the door had clearance. The cabinets at Ikea come in all different widths and heights so you can get a configuration that fits your area. I've gotten a lot of compliments on mine and it wasn't that difficult to assemble the cabinets. Very reasonably priced as well for good sturdy storage.
