this must be the king of all nooks! Tiny House idea; Instead of a lot of furniture - floor sitting raised onto a platform. flat tabletop or tray hang on wall to use when needed. Storage beneath. Narrow storage loft above.
Really cool feature element, but very little practical value as its not efficient in the space. The curtain would probably stick to you and drive you crazy, and reaching for your soaps or wash clothes would be a hassle. But, with all that said, it looks completely awesome.
