A building block having stackable half-bond symmetry and a composite insulated wall structure built therewith. The block has a planar sidewall which defines a surface of the wall structure and a serpentine-shaped opposite sidewall defined by projections. The portion of the serpentine pattern in one block half, defined by a plane parallel to the end walls and midway therebetween, is a repeat of the portion of the serpentine pattern in the other of the block halves. Inner and outer walls are each formed by stacking the blocks in a staggered half-bond relation with a generally uniform spacing between the blocks in the walls, and insulation is inserted to substantially fill the space. The length of the blocks is at least about 24 inches. The blocks of the inner wall may also be stacked in staggered half-bond relation with the blocks of the outer wall. Both vertical and horizontal rebar reinforcements may be provided.
