Slated for Perkins+Will’s ongoing Riverline development in Chicago, the River Beech Tower proposal is still very early in development so details are slim, but it would include 300 duplex units arranged around a central atrium. It would also feature indoor parks and other shared spaces.
Rising to 80-stories, River Beech Tower would dwarf wooden skyscrapers like the 21-story Haut and 18-story Brock Commons. Those two towers, and indeed many other timber towers today, are somewhat similar structurally and consist of prefabricated CLT (cross-laminated timber) sections, sometimes with added concrete cores.
Perkins+Will’s approach is different, and could reach much taller heights than currently considered possible with timber by employing a diagrid system.
“The design is made possible by an innovative structural system engineered to take full advantage of timber’s natural axial strength through an exterior diagrid system,” explains Perkins+Will.
