The following list is a snapshot from the last week or so. Several brokers said they were waiting for new downtown developments that will provide fresh trophy penthouses to challenge uptown’s dominance. Projects like Walker Tower in Chelsea (at 212 West 18th Street), where a two-floor, 12,470-square-foot penthouse is expected to list for $94 million later this summer; and 56 Leonard (due, finally, to start selling later this year, Ms. Mack said), in particular a full-floor penthouse, may shake up the status quo, and are likely to draw at least some patient billionaires off the sidelines.
THE OTHER PENTHOUSE AT 15 CENTRAL PARK WEST Sanford I. Weil may have seized the headlines this year with the $88 million sale of his 6,744-square-foot penthouse in the complex’s “house” to a trust benefiting Ekaterina Rybolovleva, the college-student daughter of a Russian fertilizer billionaire, but there is another fabulous penthouse available.
Daniel S. Loeb, who runs the hedge fund Third Point LLC, owns the largest penthouse in the taller “tower,” which brokers in my sample unanimously ranked among the Top 5 trophies. Brokers and developers around town say Mr. Loeb and his wife are quietly shopping the 10,674-square-foot space, which he bought in 2008 for $45 million, and are in search of something larger. “I heard he wants $100 million,” Mr. De Niro said.
Wishful thinking? The real estate community seems primed to keep shattering records, so a little hype never hurt. A spokeswoman for Mr. Loeb’s hedge fund declined to comment on whether he is looking to sell.
As for who is on top, Michael Gross, who is writing a book on 15 Central Park West, has no doubt. “Rybolovleva’s penthouse, grand though it is” he said, “is so far beneath Daniel Loeb’s — 19 floors to be exact — it is barely worth mentioning in the same breath, and he would have to crane his neck quite a bit downward to see it.”
THE PENTHOUSE AND WINTER GARDEN AT ONE57 The developer Gary Barnett sent shock waves through the market last month when he revealed that he had sold the two-floor penthouse atop the still-under-construction One57 for $90 million to $100 million. The buyer remains a mystery, and the closing is at least a year off, Ms. Mack said. Until then, the 10,923-square-foot residence, with its “grand salon” lording over Central Park facing north from the 89th and 90th floors, deserves a place among the Top 5 condos. But supposedly still on the market is the “Winter Garden” apartment, which occupies the 75th and 76th floors. It rates a close second. At 13,554 square feet, it’s even larger than the penthouse, with a private solarium and a formal dining room that looks as if it could seat all of King Arthur’s Court. Price tag: $115 million.
TIME WARNER CENTER: NORTH TOWER, 76TH AND 77TH FLOORS The Asian billionaire may have lost out, but the duplex apartment still makes the list. With a rare wraparound terrace at Time Warner — featuring northward views of Central Park, and of the East River and the Hudson — the residence has some ceilings that are 24 feet high, a private reflecting pool and an interior elevator. And it is on the only floor in the north tower with private terraces, Mr. Osher said. The owner is an American businessman in the finance field.
THE PENTHOUSE AT SUPERIOR INK Brokers rate the penthouse at Superior Ink, at 400 West 12th Street, as one of the two best available downtown today, though it is not for sale. The original owner, the Houston Rockets owner Leslie Alexander, sold it in 2010 for $33.5 million to Mark Shuttleworth, an entrepreneur who became the first South African in space in 2002 when he flew as a cosmonaut to the International Space Station. The 6,300-square-foot apartment has yet to be finished, Mr. Steinberg said. For those dying to capture the Hudson River views from the building, which was designed by Robert A. M. Stern and developed by Related Companies, the full 14th floor of 7,687 square feet is listed for $35.75 million.
THE PENTHOUSE AT 145 HUDSON While some brokers say 145 Hudson Street, a conversion of a 1929 Art Deco industrial building in TriBeCa, is too commercial for some discriminating billionaires, few disagree that the penthouse is stunning. The 7,500-square-foot four-bedroom four-bathroom duplex looks like a glass box in the sky. Designed by James Carpenter, it has “museum quality, high performance, insulated glass,” specially designed walls that allow artwork to be hung without fear of damage from sunlight, and 4,500 square feet of outdoor space on a wraparound terrace. It was the most expensive apartment ever sold south of Columbus Circle when it went for $30.5 million in 2009. After going back on the market for $45 million last May it was taken off less than a month later, according to Streeteasy.
