For years the catch with mass timber was the same: American architects wanted it, and American factories couldn’t make enough of it.
That’s changing. New cross-laminated timber plants are coming online to feed a market growing 20 to 30% a year. Timberlab is building a 190,000-square-foot facility that will turn out 7 to 9 million square feet of CLT annually, and Mosaic Timber’s Crescent Mills plant is set to become California’s first domestic CLT production line, according to Building Design+Construction and company disclosures.
Why domestic supply matters
Mass timber’s early U.S. projects often leaned on Austrian and Canadian panels, which meant long lead times, shipping costs, and currency exposure baked into every bid. Building CLT here changes that math. Shorter supply lines mean tighter schedules and fewer surprises, and they make timber pencil against concrete and steel on more projects. A domestic panel plant within trucking distance of a jobsite is a different proposition than one an ocean away.
The demand pulling it forward
Developers targeting lower-carbon buildings keep specifying timber, and towers like the Neutral.Edison mass-timber high-rise in Milwaukee show how far the structural system has come. Each cubic meter of wood stores roughly a ton of CO2, which turns the structure itself into a carbon argument. That’s a pitch concrete can’t make, and it’s a big reason owners chasing embodied-carbon targets keep circling back to wood.
The supply-chain read
New capacity is the precondition for the next stage of growth. As long as panels were scarce and imported, mass timber stayed a boutique choice for signature buildings. Domestic plants turning out millions of square feet a year move it toward something a mainstream developer can schedule and price with confidence. Supply, not enthusiasm, was the constraint. That constraint is loosening.
