Columbia Sheet Metal, Inc. of WA provided the gutters, downspouts and sheet metal for Super House, a three story, 32,000 square foot apartment complex in Yokohama, Japan. The $5.5 million project was sponsored by the American Plywood Association in an effort to convince code regulators that wood frame construction is safe for multistory apartments. It was the first wood frame apartment over 10,000 square feet to be built in Japan.   Puyallup, WA contractor, Nordevin, Inc. served as General Contractor and Technical Advisor. Japanese crews added the gutters, downspouts and sheet metal products supplied by Columbia Sheet Metal, using instructional videos dubbed in Japanese provided by Columbia.
