Dome

Decorative element at lower right façade, side view; Designed by Sullivan for the Gage Brothers, a hat wholesaler. He then collaborated with Holabird & Roche on the two adjoining buildings to the south so the facades would harmonize. The facades demonstrate two different approaches to the Chicago School, a design movement that led to the creation of modern commercial architecture. The buildings by Holabird & Roche are straightforward, while the facade designed by Sullivan (18 South Michigan) exemplifies his more expressive, ornamented approach. The group of three buildings is known as the Gage Group, and as such was designated a Chicago Landmark, 1996.
