Unfortunately, The Living Cube isn’t for sale. So if you want one of your own, you’ll need to either contact its designer, or head to your local home depot and pick up some nails and wood.
That said, the Living Cube is an excellent example of maximizing a small space. Not only does it house the creator’s (Till Konneker) vinyl collection, shoes and clothing, but includes a walk-in storage closet and a guest bed that is accessible by way of a ladder. It reminds me of a bunk bed, only with a massive closet and storage system built-in.
