Abstract: A connector plate for erecting structures of varied configurations. The plate comprises a main body having connections formed thereon by which the ends of six different struts can be connected together in a particular manner to form a cluster, with the number of strut ends of a cluster depending upon the selected function of the cluster respective to the building desired. The connector plate has a plane of symmetry which passes longitudinally through two of the six connections, with the two connections lying in different planes arranged at an obtuse angle respective to one another, and thereby provides attachment means by which a roof strut is connected to a vertical wall strut end. This positions the roof strut at about a fifteen degree roof pitch. There are also two right and two left strut connections lying to either side of the plane of symmetry, with the two right connections lying in the same plane and intersecting one another at a 60.degree. angle to thereby form the apex of a wall triangle.
