The George W. Dunne Cook County Office Building is located in the heart of Chicago’s central business district. Originally known as the Brunswick Building, the county purchased the building in 1996. The building offers direct access to downtown Chicago’s popular underground pedestrian pedway. The pedway conveniently connects the Cook County Office Building with the many city locales and assets, including CTA subway trains and other government offices, including the Richard J. Daley Center, Thompson Center, and the Chicago City Hall/Cook County Building. The centrally situated Cook County Office Building provides robust access to hundreds of Cook County, City and State tenants who commute to work, and also the thousands of County citizens who use the various services and departments at the building on a daily basis.
