The need for innovations in housing throughout the world increases exponentially with time. The use of known, but relatively untried material systems, geometries of articulation, and methods of fabrication for an innovative housing unit called Unikraft Model 400 are described in this paper. Section 1 describes the method of the factory and in situ fabrication of the Unit. Section 2 includes the material properties and strength properties of the materials system utilized; Section 3 includes a brief summary of the structural integrity of the 400 Unit by analytical and experimental methods. The versatility of the material and structural form of the Unikraft Model 400 makes it ideally suited for a wide spectrum of applications including temporary and/or emergency shelter, semi-permanent housing (5 to 10 year life) and permanent housing (greater than 10 years). See Figure 1. Hence depending on the options desired, the range of costs for the Unit varies from $4.00 to $12.00 per square foot.
