Mukesh Ambani Buys Tribeca Building in New York for $17.4M

15 Sep 2025 CW Team

Mukesh Ambani, India’s richest man, has reportedly purchased a building in New York City’s Tribeca neighbourhood for $17.4 million, two years after selling his two-bedroom condo in downtown Manhattan for $9 million.

The property, located at 11 Hubert Street, had been vacant for a decade, despite previous owners’ ambitious plans to convert it into a single-family mansion.

RIL USA, the US arm of Reliance Industries Limited, acquired the building for slightly less than the $20 million tech billionaire Robert Pera, chairman and CEO of Ubiquiti, paid in 2018. After acquiring it, Pera engaged architect Eric Cobb to submit plans for a 17,000-square-foot mansion, which was never realised.

In 2021, Pera listed the property along with approved designs, including Cobb’s and an earlier one from Maya Lin Studios, for $25 million. The listing described it as “an exceptionally rare offering for an end user to build a single-family mansion in an A+ location in the heart of Tribeca.”

Cobb’s proposed design featured a full-floor primary suite with adjacent workspace, an NBA-sized half basketball court, a double-height living room with courtyard access, a formal dining room with a bar, and more. Maya Lin’s concept imagined a 20,000-square-foot megamansion with seven bedrooms, 5,000 square feet of outdoor space, a half-Olympic swimming pool, and a breakfast room, among other amenities.
