Explore the viability of wooden skyscrapers, and see how cross-laminated timber (CLT) helps make these once impossible structures possible. -- Towering 85 meters above the Norwegian countryside, Mjøstårnet is the world’s tallest wooden building, made almost entirely from the trees of neighboring forests.
