A storied Fifth Avenue duplex long associated with Princess Lee Radziwill is officially spoken for, going under contract at its latest asking price of $13.5 million. The roughly 4,600-square-foot co-op offers three bedrooms, four-and-a-half baths and multiple wood-burning fireplaces, closing a very glamorous chapter on one of the Upper East Side’s most recognizable, heavily photographed interiors.
Price moves and contract
According to the New York Post, the apartment is now under contract at the full $13.5 million asking price. Listing records and property pages show that the duplex first hit the market in August 2025 at $16.9 million, then was cut to $14.9 million before settling at the current figure, per CityRealty.
Inside the Radziwill duplex
The apartment retains the generous prewar proportions and layered, European-influenced style that helped make it famous when it was featured decades ago in Architectural Digest. As Radziwill told the magazine, "I abhor the American idea of starting with a tabula rasa every few years," a line that neatly sums up the space’s collected, lived-in elegance.
Listing photos and agent notes spotlight a sizable entrance gallery, a corner living room with Central Park views, a formal dining room and a wood-paneled library, with the overall layout leaning into gracious entertaining rather than minimalist loft living, according to Elle Decor.
Market history and previous owners
The duplex last traded in 2019, when post-Radziwill coverage and property records show a sale at roughly $4.25 million. StreetEasy and neighborhood reporting also identify philanthropist Suzanne von Liebig as the owner prior to the current listing, as noted in Town & Country.
The listing is being handled by the Modlin Group, with Adam Modlin named as the listing agent in broker feeds, and MLS and broker materials showing the firm as the representative for the property. Compass and other MLS aggregators carry the current asking price and agent details, while reports note that the buyer and final sale figure have not yet been made public.
For Upper East Side real estate watchers, the pending deal is a pointed reminder that well-preserved, character-rich prewar homes still pull serious interest, even as many sellers rip out moldings and paneling in favor of slicker, contemporary looks. Radziwill once summed up her approach to interiors with a now-famous line, "I'm constantly falling in love with objects, and they follow me around the world," which helps explain why this particular co-op has continued to fascinate long after she moved on, as chronicled in Architectural Digest.
