This 258 square foot transforming apartment in Barcelona was converted from a former water tank storage space in a building’s attic. Designed by architect Barbara Appollini, the space draws inspiration from small Japanese homes and space-saving boat furniture to create a living environment where walls and furniture serve multiple functions and nearly everything can be hidden away.
