For the first time ever offered, the Penthouse at 90 Franklin Street is a one-of-a-kind opportunity in the heart of Tribeca. The residence defined by scale, light, and flexibility spans the top three floors of one of downtown Manhattans most sought-after addresses, offering over 12,700 square feet of interior space, 1,100 square feet of private outdoor space, and sweeping 360-degree views from the Hudson River to the Manhattan skyline. Originally designed by Mario Buatta and formerly home to Mariah Carey, the residence carries both design pedigree and cultural cachet. Four exposures fill the home with light throughout the day, while the private roof terrace, complete with an indoor/outdoor room and a fireplace, sets the stage for quiet mornings and landmark evenings. The layout is equally compelling in its flexibility: the 16th floor can function independently, while the 17th and 18th floors form a distinct upper duplex crowned by the terrace. Enjoy it as one expansive private home or reimagine it as an exceptional blank canvas for a developer or design-minded buyer. Please note there is a capital assessment of $1,353.76.
