Abstract: The system of the present invention relates to the formation of the two majors components of any building, namely floors/ceilings and walls. It is a principle of the present invention to pre-fabricate the form elements such that fluid concrete is poured into the forms and, once the concrete is cured, these form elements become part of the finished building. According to the present invention, the pre-fabricated wall forms include the intended finished surfaces of the walls, such as but not limited to, stone, pre-cast concrete, and metal. Alternatively, the finished surface of the wall panel may be one that will accept a final finish coating, such as but not limited to, paint and wall paper, with minimal preparation. The floor/ceiling forms are configured such that the ceiling finishing material, such as but not limited to, sheet rock, any commercially available ceiling material and suspending ceiling grid elements, may be readily attached.
