A Coral Gables mansion has been listed for $67 million, marking the second-most expensive home in Miami-Dade.

The 20,862-square-foot estate, at 1 Casuarina Concourse in Gables Estates, sits on a 3.6-acre lot that juts into Biscayne Bay. It is being listed by Coldwell Banker’s Jill Eber and Jill Hertzberg of The Jills.

Miami-Dade property records show auto magnate Alan Potamkin as the owner. He bought the property in 1987 for $2 million and began constructing the mansion.

Hertzberg said Potamkin helped design the home, which has a 937 feet of water frontage and a private beach. Potamkin, who also has a residence in Aspen, lives in the Coral Gables mansion with Brigitt Rok, a psychologist who is Miami real estate investor Sergio Rok’s ex-wife. Potamkin is now moving onto the next phase of his life as an empty nester. “It’s a change of lifestyle,” Hertzberg said.

Built in 2000, the home’s three levels include a main floor with both a chef’s and separate family kitchen, a formal dining room with a 1,500-bottle wine room, a family room, corporate office with private bath, “a his office/den and hers office/library,” children’s playroom, three powder rooms and a guest bedroom and bath, according to the listing. Additional amenities include an elevator, three fireplaces, two built-in saltwater aquariums and an aviary.

“This is a property that is just incomparable,” Eber said. “It just has everything. There is everything anyone could ever dream about. You’ve got the prestigious location, on 3.6 acres, on a peninsula.”
