Abstract: An interlocking and insulated form pattern assembly for creating a wall construction for receiving a poured concrete. A plurality of form structures each are constructed in a substantially rectangular fashion with a height, length and width and include pluralities of arcuately shaped inner walls which define both vertically and longitudinally extending concrete filling passageways. The forms are interlockingly arranged according to a desired stacking arrangement so that the vertically and longitudinally filling passageways extending continuously throughout the erected wall structure. Moisture drainage channels likewise extend in interconnected fashion both horizontally and vertically within the form structures and are arranged in alignment with identical channels in succeeding form structures to provide internal drainage capabilities to the form assembly.
