Based on the prototype of a single suitcase, various ways of use were worked out to satisfy different functions. It can be a column, a rail, a wardrobe, a fitting room, or even a display window. The design well fits into the definition of multi-brand boutique. Multiple suitcases imply the combination of various brands, and form distinctive structural languages in the space. The main goal was to create a spatial construction that's as movable and flexible as suitcase, so that the overall layout can be adjusted at any time.
