California-based design studio Minarc has created a cost-effective, innovative and energy-efficient housing solution with mnmMOD â€” a standardized but customizable structurally insulated wall-panel. This prefabricated house system uses the Structural Insulated Panel (SIP) as a building block. The mnmMOD SIP comprises recycled-steel-framing surrounded by Gypsum board and a waterproof exterior membrane, filled with airtight expanded polystyrene insulation, and all mechanical and electrical fittings. These panels can be easily disassembled and reused and make for homes with lower carbon footprints. They have been used in luxury homes, schools, habitat for humanity projects, and even the personal pads of renowned architects.
