Unfortunately, The Living Cube is not for sale. So, if you want one, you will need to get in touch with your designer, or go to your local depot and collect nails and wood.
That said, the living cube is an excellent example of maximizing a small space. Not only the designer’s vinyl collection (Till Konneker), shoes and clothing, but includes a walk-in closet and a guest bed that is accessible by means of a ladder. It reminds me of a bunk bed, only with a massive closet and an integrated storage system.
