A concept home by the students of the Institute of Structural Design at the University of Karlsruhe, Roll It is another creative exploration of flexible, space saving housing. The draft was part of a design competition in collaboration with the Institute for Industrial Design and Construction Output, and resulted in a tubular piece of architecture that symbolizes the home’s mobility. The mattress for the bed is attached by velcro, with pillows and blankets stored in a cupboard underneath. The central segment can be decoupled from the rest and used for exercise. A sink is recessed into the wall, with a water tank above it. And the toilet is mounted on hinges that keep it from turning upside-down, regardless of the surrounding motion – thank goodness.
