…Building tall with timber fell out of favor in the late 19th and early 20th centuries, when new construction codes demanded brick, stone and steel, but the benefits of wood are making architects see green. …T3, designed by the Vancouver architect Michael Green, scrapes the ceiling of current U.S. building codes, which limit the height of wood buildings to 65 feet, but in Norway, Australia and Canada mass timber buildings have topped ten stories. Last year, Green, the field’s patron saint, helped design a wooden version of the Empire State Building—102 stories high—just to prove it could be done. He says the appeal of such structures runs deep: “I’ve never seen anybody walk into one of my buildings and hug a steel or a concrete column. But I’ve actually seen that happen in a wood building.”
