Home builder sees a future with movable walls and garage-less houses

In the future, most homes won't have garages because their owners won't own cars. Rooms can be reconfigured by pushing the walls. Postal service or bike couriers might not be necessary -- drones will handle many package and take-out deliveries. As part of the Greenbuild International Conference and Expo last month, the home builder imagined residential living circa 2050 by constructing an 1,800-square-foot model home in the Los Angeles Convention Center. The sleek concept includes cutting-edge Jetsons technology.
