An uniquely improved mortar less masonry structure comprising a plurality of concrete masonry units connected to each other by metal bars and metal threaded fasteners thereby forming a reinforcing skeletal system for the masonry to utilize a post tensioned structure. The unique system has been developed with full recessed channels in the masonry unit, anchor bars that fit into the channels and extend across a plurality of masonry units and bolts that act as the tendon for the post tensioning system. This is an improved, rapidly constructed building system that demountably couples each individual masonry unit by an extended bar and bolt system. This extended bar is more efficient and easier to build with as compared to other traditional masonry structures.
