Susan Hoffmann, owner of Bozeman-based Envi Design, converted flour mill in 1930s in the town of Bozeman, Montana with spectacular loft called home. The area near the construction industry has become like living in Brooklyn, a small footprint of the house. Former office space, which covers the top floor, only 1,000 square meters. Open House combines kitchen, living room to room, office, storage, and sufficient angle to hold off the chaos. The designers want to maintain a sense of industry, plans for a possible redesign of its time. Envi Design, all photos copyright by Audrey Hall.
