With its history of timber product manufacture, the state has embraced this new material for its potential for economic development in the U.S. As in many places in the U.S., Oregon has a critical shortage of affordable housing and it has been challenging to find paths for mass timber to enter this market where light-wood-frame construction is dominant. In 2018, Freres Engineered Wood, working with the TallWood Design Institute, a collaboration between the University of Oregon and Oregon State University, developed a new product: mass plywood panels (MPP). This product provides a possibility for constructing single-family houses economically with mass timber using thin panels derived from small diameter logs. This paper describes the research leading to a pilot project utilizing MPP for workforce housing in Milwaukie, Oregon.Articleen-USCreative Commons BY-NC-ND 4.0-USmass timberaffordable housingOregonArticle
