This champagne corker of a building was designed by Hubert Burnham and Daniel Burnham Jr. for the regional offices of the Union Carbide and Carbon Company. Clad in black granite and green terra cotta, this structure soars 503’ above Michigan Avenue. The distinctive fineal (the cork) is covered in gold leaf. Art Deco bronze flanks the entrances and storefront. Bronze elevator doors, granite and marble accent the lobby. This building was the Burnham Brothers’ last major commission before the Great Depression.
