Four pavilions will be built along the Chicago lakefront as part of the inaugural Chicago Architecture Biennial. Three were commissioned, while one is the result of an open competition.

Dubbed Chicago Horizon, the competition-winning design is by Rhode Island–based Ultramoderne, a collaboration between architects Yasmin Vobis and Aaron Forrest and structural engineer Brett Schneider. Their stated goal was “to build the largest flat wood roof possible.”

During the Biennial three other kiosks will be installed along the lakefront.

The Cent Pavilion, designed by Pezo von Ellrichshausen in collaboration with the Illinois Institute of Technology, is a 40-foot tower meant to convey simplicity.

Rock, the kiosk designed by Kunlé Adeyemi in collaboration with the School of the Art Institute of Chicago, is a pop-up pavilion featuring a public sculpture composed of raw limestone blocks that once protected the city’s Lake Michigan shoreline.

Summer Vault—designed by Paul Andersen of Independent Architecture (formerly “Indie Architecture”) and Paul Preissner of Paul Preissner Architects, and in collaboration with the University of Illinois, Chicago—is a lakefront kiosk that consists of basic geometric shapes combined to create a freestanding hangout within the park.
