Chester Higgins Jr./The New York TimesThe Prasada co-op building A 12-room penthouse with panoramic Central Park views and more than 2,500 square feet of terraces atop the venerable Prasada at 50 Central Park West sold for $42 million and was the most expensive sale of the week, according to city records.
Originally priced at $48 million, the monthly maintenance for No. PHB, created from the reconfiguration of two penthouse units that had totaled 15 rooms, is $19,114.
The Prasada, on the southwest corner of West 65th Street, was built in 1907 in the French Second Empire style; the building was converted to co-ops in 1973. Besides 45 windows, the 6,500-square-foot unit has two fireplaces, four bedrooms, six baths and a corner library. There is also 50 feet of park frontage.
The master suite faces north, and a private stairway leads to a rooftop terrace with 360-degree views of the city.
The seller is Jon L. Stryker, the philanthropist/architect/social justice activist who is an heir to the Stryker Corporation, a medical supply company founded by his grandfather. Mr. Stryker’s efforts to support primate conservation through his Arcus Foundation earned him the distinction of having a newly discovered species of monkey named after him in 2010. The listing brokers for the penthouse were Robby Browne, Chris Kann and Jennifer Ireland of the Corcoran Group, and John Burger of Brown Harris Stevens.
The buyers preserved their anonymity through the Kzolp Realty Trust. The buyer’s broker declined to be identified.
The elegant runner-up, at $34.5 million, is a three-unit assemblage of condominiums on the eighth floor of the Plaza Hotel, the 1907 landmark building at 768 Fifth Avenue at Central Park South.
The 11-room corner apartment, No. 807, a 5,850-square-foot, four-bedroom five-and-a-half-bath combination of two units, Nos. 807 and 809, with 75 feet of entertainment space overlooking the park and Fifth Avenue, sold for $32 million. A one-bedroom suite across the hall, No. 808, sold to the same buyer for $2.5 million. The combined monthly carrying costs are $16,134.
