A polystyrene strip is preferably contained within each plastic stud channel. The anchors preferably include a first angle-iron plate having first and second planar portions, the first planar portion being contained within one of the concrete ribs and the second planar portion being exposed and parallel with the exterior of the rib, a second angle-iron plate having first and second planar portions, the first planar portion being fastened to the second planar portion of first angle iron plate and the second planar portion being secured to the foundation. A structure formed of such panels includes a foundation having a ledge around its edges and several of the panels positioned vertically on the ledge and secured to the foundation to form walls. Additional panels may be placed across the tops of the vertically positioned panels to form a roof. These additional panels have at least one slot for receiving the tops of the vertically positioned panels.
