Abstract
The modular lattice substructure for a playing structure, such as a toy building set, includes a planar frame having a plurality of exterior corners and a column having a height greater than the height of the frame. The column includes a lower portion and one of the lower portion of the column and a corner of the frame have a receptive connector thereon for removable attachment to a protrusion connector on the other of the lower portion of the column and a corner of the frame. In this manner, a single frame can be attached to a plurality of columns, and a single column can be attached to a plurality of frames in order to form a modular lattice substructure for a playing structure.
