One of the “most glamorous” penthouses on the Upper East Side is now in contract. 

The 6,241-square-foot home at 15 E. 69th St., was formerly owned by the late Broadway producer and socialite Terry Allen Kramer. It last asked $32 million. Kramer, heir to the fortune of Charlie Allen Jr., founder of investment firm Allen & Co., produced shows including “Kinky Boots,” “Evita” and “Hello, Dolly!”

The duplex opens from a private elevator landing to a double-height gallery, marble floors and a marble-clad staircase featuring a cast-iron and bronze banister. 

The residence boasts four bedrooms, along with more than 2,000 square feet of outdoor space across two terraces showing stunning city skyline views.

Inside, the glam details include a solarium and wood-burning fireplaces in the living room and the large main bedroom suite.

There’s also a spacious chef’s kitchen that opens to a dining room.

Building amenities include a gym, concierge, doorman and wine cellar. 

The signed contract was one of 102 signed contracts at $4 million and above for the entire month of January — the largest number since the collection of such data began in 2006, according to the Olshan Luxury Market Report, which first noted the trade. 

Listing broker Serena Boardman, of Sotheby’s International Realty, declined comment.

In the listing, she wrote, “Without a doubt [it is] the most glamorous Penthouse on the Upper East Side.”
