Idea for tiny house if you have stairs to loft. The depth of space under a staircase can be sufficient for a built-in entertainment center that houses a flat-screen TV and a bookcase to boot, along with drawers for remotes, movies, and game accessories.
Love this idea for master bath doors. Fabulous solution when space is too tight for a standard hinged door. You can also put furniture on the walls next to this opening, just leaving enough space behind the furniture for the doors to slide.
