Record tower deal for Griffin’s Citadel

Citadel founder Ken Griffin is spending on Manhattan real estate like there’s no tomorrow.

Chicagobased Citadel is inking a deal with the developer of 425 Park Ave., a luxe tower under construction, for more than 200,000 square feet, including a $300 persquarefoot rental of the penthouse.

That’s about 50 percent more than previous peak rents in the borough, which had topped out at $200 per square foot, according to a report in Monday’s Crain’s New York Business. Rent in a Class A Midtown office building averages about $80 per square foot.

“This is the highest standard of building in the 21st century on the grand boulevard of America,” de veloper David Levinson told Crain’s. “It’s blue on the Monopoly board. No one has created something like this.”

As for the luxury tax spot on the Monopoly board, Griffin, who is worth $7 billion, appears to have a lock on that.

In an exclusive Page Six report last week, The Post reported the hedgefund titan was quietly buying a $200 millionplus home in the socalled billionaires’ bunker at 220 Central Park South.

Griffin, 46, is mired in an ugly divorce from his wife of 11 years, Anne DiasGriffin, who is asking for $1 million per month in child support — in line with her current family expenditure.
