Abstract: A self-supporting wall construction comprising a plurality of V-shaped modules connected together to form a zig-zag shaped wall. Each module comprises a pair of wall segments which extend at an angle relative to one another and have their adjacent ends connected together. The pair of wall segments of each V-shaped module are connected by a substantially horizontal hinge, and the adjacent modules are similarly connected by horizontal hinges whereby the individual wall segments are permitted to vertically pivot relative to one another to conform to an unlevel supporting surface. This hinging movement also enables the individual wall segments to relatively move as required by the external loads imposed thereon.
