ABSTRACT:
A base panel for use with building blocks has a top surface, edges defining the perimeter of said surface, a circumferential wall extending downwardly from the edges, and a plurality of bores defining a grid in said surface. The bores are square, each side of the bore having a dimension X. The distance between each bore is no greater than 1/2X. However, the distance between an outer edge of the bores and the edges of the panel is at least X so that a block which fits in the bores and spans the space between the bores, can not be positioned so that a portion of the block overhangs the panel. The panel removably rests on a support.
