Fuente: WIPO "rice" The accommodation unit described carries on its underside a circular array of wheels which rest on a circular rail. Mounted on the platform are three separate room units. Each room unit has a generally circular wall and the circumferences of the walls of the three rooms intersect one another to provide a common space between the rooms to allow access to the rooms and to accommodate a central hollow service pillar which is coaxial with the rotary axis of the platform.
