At least three of the bottom panel side walls have an inner stepped flanged portion. The flanged portions are positioned in a vertical stepped relationship with respect to each one of the other one of the flanged portions. Trapezoidal front, back, and side wall panels have top edges and bottom edges. The bottom edges are longer than the top edges. The bottom edges are pivotally attached, at a bottom edge thereof, to a respective one of each one of the flanged portions so that each one of the trapezoidal wall panels are capable of being pivotally deployed outwardly between an open box-shaped shelter configuration, the top edges of each one of said wall panels being connected to a respective one of each of said top panel side walls, and a closed nested configuration where each one of the trapezoidal side wall panels are disconnected from the top panel side walls, and folded inwardly in a stacked relationship for stowage within the concave portion of the bottom panel. The front panel includes a door an latch assembly.
