A hinged door assembly comprises a hinged door portal frame and a hinged door carrying a stair on its inner surface. In one embodiment, the lower edge of the hinged door portal frame is coupled to a wall surface by a horizontal hinge, while the hinged door is coupled to the hinged door portal frame by a vertical hinge. In a second embodiment, the side edge of the portal frame is coupled to a wall surface by a vertical hinge, while the hinged door is coupled to the portal frame by a horizontal hinge. When swung open on the horizontal hinge, the inner surface of the door provides a ramp for emergency exit; when swung open on the vertical hinge, the portal frame including the door provides an opening for normal entrance and exit.
