Preservationists’ reasoning

Landmarks Illinois Interim President and CEO Frank Butterfield said the designation is needed to protect the house from demolition and preserve its architectural significance.

“We’re looking at a number of factors [as reasons to landmark the house], from the architecture to the architect, to the people connected with this place”

Architect details

The mansion was designed by Zachary Taylor Davis, an architect whose works include Wrigley Field and the old Comiskey Park.
