WA Mass Timber Accelerator (MASSTAC) is sustainably and equitably accelerating the adoption of mass timber in construction, in Washington, and nationally.

What is Mass Timber?

Mass timber is, at once, a material, a system of building, and a new paradigm for construction that is climate sustainable, beautiful, and efficient.

Washington is ready to advance the use of mass timber in construction. Mass timber can be used for everything from multifamily housing to civic buildings, office and industrial buildings, and more.

Building Better Schools with Mass Timber

Blending stories from the classroom with insights from forestry and design, this short film highlights the sustainability, resilience, and natural beauty of mass timber construction—and its connection to responsible forest management. As communities across the region face the urgent need to replace aging school infrastructure, the film poses a timely question: What if the next generation of schools could support both student success and forest health?
