Claim:
A construction set for assembling a relocatable habitat unit consisting essentially of: a base plurality of substantially flat panels, with each panel having a periphery defined by a left side edge, a right side edge, a top edge and a bottom edge; a first plurality of panels selected from the base plurality for use as interchangeable wall panels; a second plurality of panels selected from the base plurality for use as ceiling panels; a third plurality of panels selected from the base plurality for use as floor panels; a plurality of male connectors disposed along the left side edge and the right side edge of each wall panel wherein the left side edge and right side edge of each wall panel include an equal number of female connectors, disposed in opposing sequences and located on the periphery thereof such that when the left side edge of a wall panel abuts the right side edge of another wall panel each male connector abuts a female connector, and wherein the top edge of each wall panel has at least one pair of connectors and the bottom edge has at least one connector; and a hand tool with a head for rotating one male connector on a first panel about its axis of rotation for engagement with one female connector on a second panel to fixedly join the panels together during assembly of the habitat unit, wherein the ceiling panels and floor panels are interchangeable, and wherein each male connector comprises a socket mounted on a panel for receiving the head therein, and a cam lock affixed to the socket for rotation therewith, and wherein the cam lock includes a first ramp and an opposed second ramp, with the ramps inclined to form a decreasing taper with increased distance from the socket, and wherein each female connector comprises a first abutment formed in a panel and a second abutment formed on the panel, with the second abutment being distanced from the first abutment for simultaneous engagement with a respective ramp on the male connector to hold the respective panels together.
