This three-bedroom, five-bath home off Mesa Drive west of Folsom Street was built with “green” in mind — in Germany. The home was built at a WeberHaus factory in Germany to exacting standards and assembled on site. Construction waste materials entering the landfill totaled just 3 percent, including 0.7 percent in the factory and 2.3 percent onsite.
