18-28 South Michigan Avenue, Chicago Illinois.
Architects: Holabird and Roche with Louis Sullivan 1898, 1906.

The Gage Group of buildings were designed by Holabird and Roche as a single steel structure with the intent to accommodate the needs of three distinct millinery clients.  The client for the Gage Building hired Louis Sullivan to design the facade of the 18 S Michigan building.  The buildings are on the National Register for Historic Buildings, listed as Chicago Landmarks, and are beneficiaries of the Landmark Preservation Council of Illinois Facade Easement Program. 

Klein and Hoffman has designed and implemented a facade restoration program of the buildings including extensive terra cotta repair and replacement to match the original Louis Sullivan ornamentation, brick repair and replacement to match the original color and detailing, window repair and replacement, and aided the Owner in the pursuit of numerous historic preservation tax incentive programs.  Completion for the Phase I of the terra cotta and brick restoration is anticipated in 2005; completion for the windows and storefront is anticipated in 2006. 

Extensive research into the historical archives, public and private institutions, and private collections have provided architectural and ornamental information for the restoration of the buildings.
