Taking advantage of all your usable space is important, especially if your home is not large. Under the stairs is a great place to find additional space. The easiest way to use this space is to enclose the area and install a door for access. The space is great to store games and other items you don’t use every day. If your stairs are enclosed with drywall, you can open the area, frame in a door, add some shelves and have instant storage. Disguising the door can be managed by adding some decorative moldings for visual interest to an otherwise plain wall.
