A new wave of U.S. K-12 construction is putting mass timber front-and-center. The Softwood Lumber Board (SLB) and the U.S. Forest Service have awarded $1.8 million to four school-district projects through their 2025 “Mass Timber Competition: Building Sustainable Schools” initiative. The goal: accelerate the use of cross-laminated timber (CLT), glued-laminated timber (glulam) and other engineered wood systems in classrooms, libraries and athletic facilities nationwide.
The winning projects offer a compelling mix of design innovation and sustainability focus. In Portland, Oregon, Cleveland High School will rebuild its campus using two four-story mass-timber towers and a bridge structure using Type-IV HT framing. This frees up outdoor space, while cutting exposed concrete and steel.
In Ann Arbor, Michigan, the new New Lawton Elementary School will target Passive House performance and full-electric operations, with visible timber elements designed to enhance biophilic learning. In Hawai‘i, New Central Maui School will serve students and the wider community. The school doubles as an emergency shelter, while using glulam and CLT to support resilience.
Not to be outdone, in Washington, D.C., Whittier Elementary School is undergoing a net-zero renovation and expansion featuring mass timber framing in place of steel.
Why does this matter for industry professionals? Four key drivers:
- Carbon & sustainability: Each project emphasizes low embodied carbon and wood based natural materials, responding to increasing ESG demands.
- Speed & efficiency: Mass timber systems enable faster construction schedules and less dry-in time – critical in K-12 budgets.
- Design flexibility: Exposed timber floors and glulam allow architectural statements and acoustics improvements without relying on suspended ceilings.
- Market growth signal: With funding and high-profile use cases, mass timber is moving beyond niche into mainstream for institutional building types.
For architects, project managers, and executives in manufacturing, construction and wood-products supply, this competition marks a clear inflection point. The funding is modest, but the real value lies in validation, design-prototype learning, and scaling potential.
Building teams should watch for upcoming case studies, life-cycle assessments and design-guides that the winners will share – as they herald the next wave of CLT adoption.
