Roanoke Building and Tower

Address: 11 S. LaSalle St. Year Built: 1915 - 1925 Architect: Holabird & Roche , Rebori, Wentworth, Dewey & Mccormick Date Designated a Chicago Landmark: December 12, 2007

Built in stages, this building¿s configuration (combining a massive office block originally called the Lumber Exchange Building with a slender tower addition) reflects the influence of Chicago¿s pioneering zoning ordinance of 1923, which encouraged the building of set-back skyscrapers. Designed in an unusual Portuguese Gothic Revival style, the building also exemplifies the importance of LaSalle Street as Chicago¿s premier historic street for finance and commerce.
