Unique Challenges, Creative Solutions

Solhaus represents the end result of the clean-up of the former Gopher Oil Superfund site, which had polluted the water table and neighboring properties for over 80 years. This important work was the culmination of a three-year collaboration between a private developer, the city of Minneapolis, Hennepin County, DEED, and the MPCA and exemplifies a transformation from industrial waste site to 75 units of sustainable green housing.

Transforming this zero-lot-line former Superfund site into green housing presented unique challenges. Greiner worked closely with the developer, design team, and city, county, and state officials to ensure that every aspect of this complex build was fully compliant and supported Solhem's vision for sustainability. Greiner worked through the winter and used locally sourced construction materials to meet an ambitious schedule and minimize the project's carbon footprint, delivering beautiful, sustainable housing right on schedule.
