Designed by architects Philip Johnson and John Burgee, a Chicagoan, 190 South LaSalle adopts the visual language of earlier Chicago buildings but supersizes its decorative elements to add a touch of drama and fun. This is a common characteristic of Postmodern buildings—oversized scale combined with over-the-top symbolism and in-your-face colors—and depicts the architectural freedom that flourished in the 1980s and ‘90s. This style was an explicit response to the strict precepts of the International Style, epitomized in Mies van der Rohe's steel and glass structures.
