Rare NYC Penthouse with Golden Dome Listed for $13.5M

In a striking blend of history and modern luxury, a penthouse in Chelsea is now on the market for a staggering $13.5 million. This residence is notable not just for its price tag but for boasting one of the rarest architectural features in New York City: a gold-coated cupola. Set atop the landmarked O’Neill Building at 665 Sixth Avenue, this duplex spans approximately 4,800 square feet and includes over 2,500 square feet of private outdoor space, making it a true rarity in the competitive Manhattan property market.
A Rare Architectural Gem
What makes this Chelsea penthouse truly unique is its cupola—one of only three such residential structures in all of New York City. The building itself, erected in 1887 as a women’s mill, has a rich history that adds to its allure. The listing broker, Peter Ocean of Serhant, emphasizes the significance of this feature, stating, “There are only three apartments in the city, including this [penthouse], which have cupolas, and this one is the most recognizable of them all.” This historical connection is essential, as it reflects both the architectural ingenuity of the past and its reimagination for modern living.
The Transformation of Space
The 43-foot dome, originally an architectural showpiece, has been ingeniously transformed into livable space. Currently set up as a home office, it can easily adapt to serve various functions—be it a media room, lounge, or a private retreat. This flexibility appeals to a wide range of potential buyers who value both historic charm and contemporary functionality.
