Ever since the 10-story Home Insurance Building in Chicago was called the first "skyscraper" in 1885, architects have been striving to create ever-taller buildings. Ten stories quickly became 20, 20 became 50, and on and on. In 2009 the Burj Khalifa in Dubai became the world's tallest building, with its 154 floors towering above ground level.

So why is the mayor of Portland, Oregon, calling a modest 12-story tower set for completion there next year “a true technological and entrepreneurial achievement?" It’s not the affordable housing the building affords, nor its dozens of bike racks or even the roof farm that has Ted Wheeler gushing. It's that the Framework apartment building will be made almost entirely of wood, reports NBC News.
