A two-piece building block assembly includes a hollow block and an inner piece. The hollow block has a plurality of studs extending from a top thereof, an opening defined in an underside thereof and a plurality of ribs extends from side walls thereof. The inner piece is corresponding to and received in the opening of the hollow block. A plurality of recesses is defined in the periphery of the inner piece and located corresponding to the studs. The inner piece includes support boards. Each support board is defined between the adjacent recesses and disposed between the two adjacent ribs that are located on the same side wall of the hollow block. The inner piece reinforces the opening of the hollow block to prevent the opening from being deformed. Thus, the building block assembly does not have to be made of high-stiffness or high-density materials.
