Not sure the description of "cross laminated timber" as "beams" is really gives you a sense of what this is. CLT is more like plywood on steroids -- giant panels -- and I think there's now a plant making this stuff in Douglas County.. Pretty cool to see what's been done with this in other parts of the world.
