The initial keywords: space, storage, future. In the future space becomes more desireable, because the big appartment buildings are taking over the normal 1, 2 or 3 level houses. It's more efficient because you will need less square meters to house people. therefore the focus for the future is on height and not in width. But current storage furniture is designed for average humans with a length of approx. 1.8 meters so everything is reachable. So to be efficient also our furniture needs to grow in height in stead of width. This StairCASE is the result of these facts.
