Abstract: An improved automated parking garage structure comprising a supporting framework bearing a plurality of vehicle parking stalls arranged in a radial manner on a plurality of levels about a central core. Each of the stalls support a vehicle on a series of fingers. An elevator tower is located within said central core and has an elevator platform adapted for vertical travel, the tower rotating about a vertical axis. A transfer lift for transferring a vehicle between ground level and a level for transfer to or from said elevator platform; is located at ground level and accepts vehicles for parking and return. The elevator platform includes an extension carriage for transferring a vehicle between the platform and the stalls and transfer lift. Operation of the transfer lift, elevator and tower are coordinated by an automated control system, which may include a first unit located at the tower and a second unit, serving as a customer interface, at a remote location.
