摘要： A prefabricated building unit has a framed inner stud wall to which is joined an intermediate wall of insulation board and an exterior wall of concrete, the concrete being poured on the intermediate wall and over angled, protruding nails that fasten the intermediate wall to the stud wall. A plurality of the building units are combined to complete the walls of a structure, the method of joining being to weld together reinforcing bars extending from the concrete portion of each unit and then to pour a pilaster over the joined reinforcing bar. The exterior of the concrete wall is finished during prefabrication with exposed aggregate and exterior varnish.
