The mansion was designed by Detroit architects Smith, Hinchman, and Grylls, with input from the Olmsted firm. Its classic, simple proportions were enhanced with elegant details that included a slate roof, copper eaves and detailing, and a Pewabic ceramic fountain. Outwardly traditional, the house incorporated the latest in modern technology. Beneath the limestone exterior (hand-chiseled to simulate age), its structure was steel and concrete. It boasted what is believed to be the first residential air-conditioning unit outside of New York City, showers with ten heads, and vented closets with lights that went on when the door opened. There were bells every where--Carrie Earhart never had to go more than ten feet to summon a servant.
