They took the opportunity to consolidate 50 different state of Illinois agency offices into one new building. Joining three other major government buildings standing within a city block of each other, the Thompson Center was to be a “peoples’ center,” an easily accessible and inviting place to do business with the state of Illinois—as well as shop and dine.\u003C/p>\u003Ch4>A POSTMODERN DOME\u003C/h4>\u003Cp>Tall, gridded walls face LaSalle and Lake streets, but on the other sides of the building, Jahn broke from the rigid straight lines of \u003Ca href=\"https://www.architecture.org/learn/resources/architecture-dictionary/entry/mid-century-modernism/\" rel=\"noopener noreferrer\" target=\"_blank\">modernism\u003C/a>.

An enormous skylit rotunda, 160 feet in diameter and 13 stories high, is lined with balconies of open office space.
