Abstract: In a building construction individual concrete panels are formed utilizing a horizontal casting platform to tailor the panels to meet structural and aesthetic requirements with each panel having abutting joints that interlock. The method of installing the panels to erect the building is to prepare the strata including a final layer of mixed sand and stone, wetting the surface, erecting the panels in position and temporarily bracing them and vibrating the strata, attaching the adjacent panels and removing the bracing. The panels are individually molded with a interlocking base on a planar horizontal table including the form edges that are oriented to define the configuration of the panels.
