125 Haus is a home under construction that could become a model for next-gen housing that’s extremely energy and cost efficient. Architect and owner Jörg Rügemer* expects this to be Utah’s most energy-efficient and cost-effective house, which is saying a lot given the fact that the Breezeway House obtained Passive House certification on a budget. When complete, 125 Haus will have three bedrooms, a studio, and 2,400 square feet with an expected construction cost of $118 per square foot.
This is The Edge, a factory-built home inspired by Mies van der Rohe’s Farnsworth House (not to be confused with the E.D.G.E. prefab). UK-based Boutique Caravans designed and built the modern prefab – which measures 22′ x 42′ – with cold-formed steel, SIPs, and triple-glazed windows. It’s a show house in Penmayne Edge Park in Rock, North Cornwall, a community of 10 low-energy holiday homes in the UK.
