EUGENE, Oregon — A University of Oregon research and design team has completed construction on a prototype house that showcases a sustainable, energy-efficient alternative to traditional home construction. Researchers with the TallWood Design Institute, a collaboration of the UO and Oregon State University, spent two years designing and building the 760-square-foot house made from mass plywood panels manufactured in Oregon by Freres Engineered Wood. The institute will welcome visitors to an open house Nov. 7 showcasing the project. …The test home demonstrates a new construction model that could help with housing shortages, the economy and wildfire mitigation, said Judith Sheine, a UO professor of architecture. …This first prototype marks a big step forward, Sheine said. The model home could represent a new solution to help address Oregon’s housing crisis, especially affordable options known as middle or workforce housing.
