A prefabricated structure, illustratively a residential dwelling, having a prefabricated central core and a plurality of prefabricated floor, wall and roof members that pivotally fold inwardly about the central core to produce a compact folded structure which is easily transportable, and pivotally fold outwardly about the central core for quick and inexpensive on-site installation. Also, methods for erecting sturdy habitable structures and the sturdy habitable structures themselves.
