The lifter (elevator) moves vertically and the dolly moves horizontally back and forth at a given floor to store the car in the parking compartment. The top of the external turntable (empty space in front) can be used as a parking space.
The occupied space is a standard dimension when sandwich panels are used for the exterior walls. In the case of a high-roof car, the height will be increased by 450mm per floor. If the height exceeds 43,500mm, a separate study is required.
