A shipping system is configured to facilitate transfer of a package into and/or out of a room in a building. The shipping system is for controlling a shiftable panel of the building to selectively provide a path into and out of the room. The shipping system includes a control system. The control system broadly includes a vehicle sensor and a system processor. The system processor is configured to receive package identification data associated with the package, have the panel opened to allow room ingress and egress along the path based on the package identification data, move an autonomous vehicle to a location adjacent the panel to facilitate package transfer, based on vehicle location data, and have the panel closed to restrict room ingress and egress along the path in response to a determination that the package has been transferred into or out of the room via the path.
