Beginning in the early 20th century, the building underwent three major renovations. In the first, from 1905 to 1907, Frank Lloyd Wright was retained to remake the interior spaces. In keeping with contemporary tastes, Wright's design covered Root's elaborate wrought iron finishes with white carved Carrara marble surfaces. Wright was highly regarded by the public at this point, and his changes brought enhanced status to the building, making the Rookery one of the most sought after buildings of Chicago. Some of Wright's other changes included incorporating simplified ironwork and adding his trademark style planters and light fixtures.
