Big Ticket | Sold for $33.5 Million

Librado Romero/The New York Times The Park Laurel condominium

A large and lavish duplex penthouse that dominates one of the asymmetrical towers at the Park Laurel, a luxury condominium residence built in 2000 and anchored by the historic McBurney School, sold for $33.5 million and was the most expensive sale of the week, according to city records.

The penthouse, No. 29A, a sprawling 15-room combination of three units designed by the architect Alan Wanzenberg for a previous owner, occupies 7,738 square feet of interior space and has a 1,244-square-foot wraparound trophy terrace that faces south and captures both park and city views. There are seven bedrooms, five bathrooms, two powder rooms and a perso nal elevator entrance.

Special attention was paid to soundproofing: a 2010 listing for the apartment noted that, in addition to radiant-heated tiles in the master bath, the unit had been soundproofed by JRH Acoustical Consulting, with all pipes insulated to achieve “sound elimination.” Carrying charges are around $20,000 per month.

The Park Laurel, at 15 West 63rd Street, was designed by Beyer Blinder Belle and Costas Kondylis with an eye to the Modernist architecture at Lincoln Center nearby. Previous residents include J. Michael Evans, a Goldman Sachs vice chairman and potential successor to Lloyd C. Blankfein. His 5,000-square-foot Gwathmey Siegel-designed duplex penthouse, No. 40/41, is currently listed for sale with Douglas Elliman Real Estate for $26.5 million. For $29.25 million, Mr. Evans, who decamped to 995 Fifth Avenue this summer, will throw in an auxiliary two-bedroom unit he owns on the 14th floor.

When No. 29A changed hands in 2010, the seller was the hedge-fund honcho Ephraim F. Gildor, the asking price was $28 million, and the Swiss buyers, Peter Edward Chadney and Simone Cecile Von Graffenried Simperl, paid $23.98 million. Agents from Douglas Elliman represented both parties in the deal. This time around, there was apparently no formal listing; both Janice Chang and Raphael De Niro, who were involved in the 2010 transaction, confirmed that they had no connection to the $33.5 million deal.

Mr. Chadney and Ms. Simperl used Park Laurel Ltd., a company based in Zurich , to identify themselves in city records, and the buyer, based in Los Angeles, acquired the penthouse under the shield of a limited-liability company, Park Laurel Acquisition.

The sale appeared in city records on Dec. 4 and a post that day on the Web site of The Real Deal identified the buyer as Riza Aziz, an investment banker and a founder of Red Granite Pictures, a fledgling film company in Beverly Hills, Calif. Mr. Aziz is a son of Tun Abdul Razak, the Malaysian prime minister from 1970 to 1976. His film company's debut offering was “Friends With Kids”; it is currently producing “The Wolf of Wall Street,” a $100 million venture directed by Martin Scorsese, starring Leonardo DiCaprio and filming in New York City. According to The Hollywood Reporter, Mr. Aziz and Mr. DiCaprio are fast friends.
