Former Sanford Bernstein COO taps new broker to market Palm Beach County’s largest condo unit

Senada Adžem, director for Douglas Elliman Florida in Boca Raton, has taken over from Scot Karp of Premier Estate Properties as the listing agent for the largest penthouse in Palm Beach County and the second largest in all of Florida, she told The Real Deal today. The spread is at the Toscana North condominiums at 3700 South Ocean Boulevard.

Adzem, who recently represented Michael Lorber in a deal for a Palm Beach pied a terre, said she picked up the listing two days ago and will be hosting cocktail receptions in New York and the Hamptons this summer to help find a buyer for the 11,662-square-foot property owned by Sanford Bernstein founder and former COO Shepard Osherow.

The European-style penthouse, with 9,290 square feet of living space and a large terrace, first hit the market in July 2011. Karp had it for a nine-month season. It was not immediately clear why Osherow had chosen to give the listing to a new broker.

The custom-designed home is comprised of two penthouses in the South Florida condominium with two penthouses directly below. The residences were combined by Osherow and wife Sally Bosch Osherow when they first bought into the building during its construction phase in the early 2000s. It features five bedrooms, a home theater and a library as well as office space. The property comes with a membership at the exclusive Boca Raton Resort & Club.

Adzem has listed the property for $9.85 million, she said.

The buyer will likely be someone “very sophisticated when it comes to design,” she said.

She added that she plans to leverage Elliman’s network of prospective buyers all across the country to make a deal happen. Marketing of the property will begin tonight with an exclusive wine-tasting event for a small pool of high-end brokers in the area, she said.

Osherow could not immediately be reached for comment. Karp was not immediately available.
