Abstract
The modular lattice substructure for a playing structure, such as a toy building set, includes elongate beams, elongate joists, and columns having a height greater than the height of the elongate beams and joists. The sides of the columns have a protrusion connector removably attachable to a slot connector in the ends of the elongate beams and the ends of the elongate joists.
