Susan Crown, a scion of the wealthy Crown family, has sold her 13-room Gold Coast mansion-though only after accepting a bid that was nearly 30 percent below her asking price. The triple-turreted Romanesque house, built in 1890, sits on a suburban-size lot: 60 feet wide by 110 feet deep, a rarity in this densely packed neighborhood. Behind its Georgia marble façade, the house has 8,000 square feet of space on four levels, seven fireplaces, some Tiffany stained glass, a designer kitchen, and a lap pool in the basement.

Crown, 49, is a principal at Henry Crown and Co., which owns pieces of the New York Yankees, the Chicago Bulls, JPMorgan Chase, Hilton Hotels, Rockefeller Center, and ski resorts in Aspen, Colorado. The Crown family fortune, which Forbes magazine estimates at about $4.5 billion, originated with Susan’s grandfather Henry Crown, who in 1919 started a company called Material Service; the company later merged with the engineering powerhouse General Dynamics. The daughter of Lester Crown, Susan Crown is married to William Kunkler III, an executive with another Crown company, CC Industries.

Crown, who had owned this house since 1989, did not respond to a request for an interview, nor did her agent, Suzanne Gignilliat of Koenig & Strey GMAC. The buyers are not yet identified in public records.
