Mass Timber has been a core part of Waechter Architecture’s (WA) practice over the past decade. The Portland, Oregon–based firm has been studying and developing projects to expand knowledge of this increasingly popular material in the region and test its construction efficiencies, energy performance, and cultural and market adoption across design typologies. WA’s research on mass timber architecture received a grant from the USDA/U.S. Forest Service Wood Innovations Program, with additional support from the Softwood Lumber Board. The firm’s studio space, the Mississippi Workshop, is a three-story prefabricated mass timber structure designed, developed, and built by WA as a test bed for its in-house all-wood construction research. The building is the first commercial project in Oregon to use mass timber construction for all building components. Except for the sheathed metal exterior and the integrated radiant concrete flooring, the firm used exposed wood for all surfaces, purposely avoiding hybrid systems.
