The Council on Tall Buildings and Urban Habitat has designated the 284-ft-tall Ascent in Milwaukee as the world’s tallest timber and concrete hybrid structure. The 25-story Ascent has broken height and size records both for pure timber and composite timber and concrete structures anywhere—but by only 4 ft in height.
The 488,000-sq-ft residential building barely exceeds the height of the world’s tallest pure-wood building—Mjøstårnet, a 122,000-sq-ft mixed-use building in Brumunddal, Norway, completed in March 2019. Measured in meters, Ascent is 86.6 m, Mjøstårnet is 85.4 m and the timber-concrete hybrid mixed-use building, HoHo, in Vienna, is a close third at 84 m.
