A checker brick has a plurality of walls intersecting at a plurality of spaced intersections. Four walls extend outwardly from each intersection in equidistantly-spaced relationship to one another. One of the four walls at each intersection is a common wall that extends between adjacent intersections. The other three walls at each intersection are independent walls. Mating projections and recesses are provided on the opposite surfaces of the brick at the intersections for interlocking bricks stacked in tiers.
