The primary objective of the present invention is to provide an interlocking, interchangeable wall system allowing for the formation of a plurality of form structures. Each parallel sidewall is embedded with stones or other materials into a composition base on one side. On the opposite side, the sidewalls are embedded with metal lathing and hardware to connect to bracing which connects to the opposing sidewall to form a plurality of structures, including an interlocking block system. Each sidewall interlocks with the panel or block next to it. When connected, the resulting interlocking composite blocks may be used in the construction of walls or other structures. The resulting sidewalls may be used in the decoration of existing construction or other structures. The present invention provides a significant improvement in labor and customization of structures.
