A view on how the priciest Manhattan apartments stack up against, well, everything

Just three years ago, a penthouse at 15 Central Park West sold for $88 million, shattering the record for the priciest New York City home sale ever. At $13,000 per square foot, it’s still a record holder, but the overall price looks like child’s play compared to today’s mega sales. Late last year, for example, Gary Barnett’s Extell Development closed a $100.5 million penthouse at One57 (for about $9,200 per square foot). But even that record may not stick for long. As The Real Deal reported exclusively last month, the Chetrit Group and David Bistricer’s Clipper Equity plan to list a unit for an audacious $150 million at 550 Madison Avenue, the former Sony headquarters, which they are converting to condos. An offering plan filed with the state Attorney General’s office shows it will measure a whopping 21,504 square feet — a vast space holding eight bedrooms, eight bathrooms and 10 powder rooms. Shockingly, at about $6,975 per square foot, it may be a good deal — at least for a small group of 1 percenters. By comparison, the Zeckendorfs plan to ask $130 million, or $10,489 per foot, for the triplex atop 520 Park Avenue. And the city’s current pricing listing Downtown is a $118 million three-unit combo at the Battery Park City Ritz Carlton for roughly $7,600 a foot. Here’s a look at how these record-breakers compare to everything from the world’s most expensive homes to municipal budgets to the economies of small countries.

The home has three helicopter pads, underground parking for 160 cars, and a staff of 600.
