Look for dead space under stairs and in deep walls. There is often room under a staircase for a small closet, powder room, or even built-in shelves for cataloging books, files and other knickknacks that create clutter.
This is a fabulous storage solution for your shoes. Instead of letting your shoes clutter up your entrance way or take up valuable closet space try this out. Transform some stair steps into a shoe drawer.
Creative ideas for using the space under the stairs. Brilliant use of space! Not nuts about the bathroom idea though. I guess if you had a tiny home with no main floor powder room it could be workable.
