Building element and method

A construction system, comprising:

• at least one wall comprised of a plurality of vertically-stacked building elements having a proximal end, a distal end, and a length between said proximal and distal ends, wherein said building elements are attachable end-to-end, each building element comprising an integral combination of a top member, a center member, and a bottom member, said top, center and bottom members being equal in length, wherein the center member is offset from the top and bottom members lengthwise so that the distal end of the center member extends further than the distal ends of the top and bottom members;
• wherein the proximal ends of the top and bottom members each comprise a proximal vertical hole extending therethrough, and the distal end of the center member comprises a distal vertical hole extending therethrough;
• further wherein each building element comprises one or more medial vertical holes extending through all three members at one or more points along the length between said proximal and distal ends;
• further wherein the top member is affixed to the center member and the bottom member is affixed to the center member.
