CHICAGO — …Milwaukee, our neighbor to the north has become a hotbed for the development of timber towers — tall buildings that use relatively new mass timber technologies that can replace the steel and concrete traditionally used to support such structures. Since 2022, Milwaukee has been home to the tallest timber tower in the world — the 25-story Ascent MKE at 284 feet in height. That’s no Sears Tower, but when you consider that most wood-framed buildings are one to four stories tall, it’s quite an achievement. …For all the stunning achievements that Chicago architects and engineers have accomplished over the last century and a half, there’s still a deeply conservative streak that runs through the city’s building culture. Fire, through several key historical events, is at fault. …So, perhaps it’s not surprising that we now lag many places in the development of new construction with mass timber.
