A construction system using framing components in the shape of a double-Y member wherein two longitudinal members which are connected to form a right angle are then connected to one end of a third longer longitudinal member at the vertex of the pair. Another pair is connected at the other end of the longer member, thus forming a Y-shape at each end and wherein all five longitudinal members are co-planar. Multiple ones of these double Y elements are joined at the ends of the double Y, each double-Y element being rotated 90° before joining to the next one. The resulting construction yields a three dimensional framework which defines a repeating pattern of volumetric shapes which all fall into one of two categories: cubes and rhombicuboctahedrons (a 26 sided three dimensional shape which can be described as a cube which has been mitered at each corner and each edge).
