The ORB is anti-gravitational.  It can spin, flip and float.  Inhabitant can climb into the ORB through a hatch on either side and can move from workspace to sleeping space.  Walls are translucent, always allowing panoramic views.  The ORB is sited in GoogleEarth in three places, lashed to a water tower above the building where I work in Queens, bobbing in the South Pacific and floating above the Bosporus.
