Apparatus for constructing a variety of structures from a limited number of different components includes at least two generally planar members (10, 11, 12; 25), each having along at least one edge an elongate socket (13) formed from two aligned, spaced-apart sections ( 14, 15 ) , and at least one connector (18; 27) including a pair of cylindrical rods (19, 20; 29, 30 ) held in laterally-spaced relationship, the diameters of the rods being such as to provide a close fit within a socket (13).
