The one great thing about a laundry room is you do not need that much space. Convert a closet into your dream laundry room. A stackable arrangement conserves space but you can also install side by side washer & dryer with a counter top and cabinets above.
Kitchen or anywhere DIY. Seems simple enough, depending on your gap between shelves, anywhere from ropes to ropes for your spacing. You could even use wider wood, just adjust your rope length to accommodate your width and height of your shelves.
