Reclaimed barnwood wall- basement stairs - love this idea for a spot that is hard to decorate. [we're changing the varnished plywood wall next to the stairs, i wonder if we could do a bit of this idea. or a textured wall paper]
This is intended as a hidden doorway, but it's a reasonable way to design closet doors. That's because you're not expecting furniture to be placed in front a closet door. So, adding shelving makes use of that otherwise dead space.
