Denver, Colorado is about to get … the tallest mass timber building in the city, which will break ground summer 2023. …the 12-story “Return to Form” building will provide residential housing with a total of 84 dwellings. …The architectural firm Tres Birds, …is optimistic about the future of mass timber as a viable and sustainable building material. The technology uses trees with a small diameter that are harvested from sustainably-managed forests to ensure renewability and health of the resource. …“The recent development of mass timber construction allows us — for the first time in history — to design high-rise building structures out of a renewable resource: trees,” said Michael Moore, founder of Tres Birds. …The design is attracting attention with Tres Birds and the development team winning the 2022 Mass Timber Competition: Building to Net-Zero. The “Return to Form” project will share in a $2,000,000 prize sponsored by the Softwood Lumber Board and USDA Forest Service.
