Thompson Center – Helmut Jahn
Completed in 1985 and designed by Helmut Jahn, the James R. Thompson Center in Chicago is a bold example of Postmodern civic architecture. Its sweeping, curved glass façade—referencing the dome of the Illinois State Capitol—symbolizes transparency and accessibility in government, breaking from Modernist rigidity with vibrant color and expressive form.
The building’s southeast profile is a slice of a hollow sphere, clad in blue glass and salmon-colored steel, while its monumental 13-story atrium, topped with a skylight, creates a dynamic public interior. Encircled by open office balconies and animated by escalators and exposed elevators, the space functions as a vertical civic plaza.
At ground level, a large rotunda floor cutout connects to a food court, state services, and pedestrian passages—underscoring the building’s role as a populist, accessible hub within the city.
