This open timber pavilion with an overhanging roof was named the winning design of the Lakefront Kiosk Competition in 2015, and now it has received a citation in the R+D Awards, ARCHITECT’s annual celebration of innovative research and technology. Completed last October in Grant Park for the Chicago Architecture Biennial, Chicago Horizon has a square, flat canopy measuring 56 feet on each side—the maximum length of timber that can be legally carried by a truck.

The canopy consists of two plies of cross-laminated timber (CLT) panels laid crosswise to each other. The 14 panels, each 8 feet wide and 4.125 inches thick, are topped by a rubber waterproofing membrane and gravel ballast. Overall, the roof weighs around 135,000 pounds, nearly half of which is the CLT itself.

“This is a classic minimalist construction," one juror said. "The more you contemplate it, the more its subtle sensibilities draw you in.”
