A boat barn by architect and mass timber proponent Michael Green implements construction-grade plywood to create a strong structural foundation. It stands as just one example of Green’s belief in wood as the answer to building a more sustainable future. "Cities will become healthier places when we choose to work in natural materials such as wood," explains Green, who lectures internationally on the subject. Green is a world leader in the design of mass timber structures, and perhaps one of the most humble architects in the business.
