In my neck of the woods it’s pretty common to have one of these good for nothing 8‘ x 8‘ “bedrooms.” In my house this room never got used so I decided to add an IKEA kitchen cabinet base to the bottom of the closet to get a little more functionality. The doorway was too narrow for bypass doors, I hate bi-folding doors and an outswing door would be in the way. This IKEA cabinet is way cheaper than what I could build it for once you factor in the cost of labor, hardware and material. I just threw together some quick and dirty doors and drawer fronts and it’s good to go. Why spend a lot of money on a room you don’t use right?
