You’ll need $98M to live up here

Now this is sky-high.

Two penthouses at a luxury building next to Carnegie Hall are being shopped around by the city’s biggest brokers for a stunning $98.5 million each — and not a single brick has been laid!

The swanky pads at ONE57 (pictured) — slated to be the city’s largest residential tower at 90 floors — are the most expensive preconstruction condos ever, real-estate sources said.

The one on the 90th floor will clock in at 10,923 square feet and the one on the 75th floor will be 13,554 square feet.

Construction will be finished in two years.

A Park Hyatt hotel will occupy the bottom half of the building.

The penthouse price tags are lower than those selling at 15 Central Park West — but are expected to jump 25 to 50 percent after the building is completed, said Gary Barnett of Extell Development.
