In 2023, Swedish architecture firm C.F. Møller will transform the Stockholm skyline—and perhaps the very notion of skyscrapers. Last December, the designers won a competition organized by HSB Stockholm to honor the local real estate titan’s upcoming centenary with an ostentatious new high-rise. Møller submitted three flashy, modern designs, but the public latched onto one in particular that will sound, to many, intuitively insane: a thirty-four story tower made almost entirely out of wood, save for a spindly concrete core and a few steel poles on the ground floor. If constructed, the tower will be the largest mostly-wooden structure in the world. But rather than a one-off, it could be the clarion call needed to rouse the public around a new architectural trend.
