in transforming the mobile elevated building assembly back and forth between the configurations corresponding to the installed mode and the transportation mode as in moving one moves the other the rear footing 65 for the building 10 above the top of the tower 20 is attached to the top of stairs platform 64 such that when the top of stairs platform 64 is horizontal as in the installed configuration the rear footing 65 will be in place to help support the building above the tower 20 and when the staircase 50 is folded and lowered after the building 10 has been removed from the assembly 100 to transform the assembly between the two modes installed mode and transportation mode the top of stairs platform 64 with the rear footing 65 will have rotated upward putting both clear of the building 10 this clearance allows for the building to be shifted rearward to clear also the forward footing 27 as needed to lower it into the tower 20 when transforming to the transportation mode one skilled in the art will recognize that other means could be used to accomplish moving the top of stairs platform 64 and or the rear footing 65 into and out of place for configuring the installed mode and one skilled in the art will recognize that the top of stairs platform 64 and foldable staircase 50 could be hinged separately from one another or even not at all in other implementations of the invention s incidentally staircase bannisters and other handrails are not shown in these figures in order.
