Building Trends: Mass Timber

Quarterly Update + Map of U.S. Mass Timber Projects

WoodWorks tracks mass timber projects across the U.S. as a resource for developers and design teams who want insights into market trends.

As of September 2021, 1,241 mass timber projects had been constructed or were in design in all 50 states, in the multi-family, commercial, or institutional categories.* This total includes modern mass timber and post-and-beam structures built since 2013.

WoodWorks has been supporting this evolution from the outset. In 2015, we provided technical assistance on a handful of projects where the architect, engineer or developer had an interest in using mass or heavy timber. Five years later, we’ve supported most of the projects on the map above, including 93% of the buildings in design, and 80% of those completed.

We can help make your mass timber project a reality!

Mass timber now comes in many forms. Products such as cross-laminated timber (CLT), nail-laminated timber (NLT), heavy timber decking (3x or 4x boards), and traditional post-and-beam framing are well established, while newer products such as dowel-laminated timber (DLT) and mass plywood panels (MPP) are already gaining traction.
