The new 10-story office building being developed at 860 Washington St. in the Meatpacking District next to the High Line is becoming the new “It” building.

Close to being completed by Romanoff Equities and Property Group Partners, there are now at least three leases out with private equity firms for full-floor offices.

“It’s becoming a very popular location for family offices and hedge funds because their owners live in the area,” said Robert Emden of Newmark Grubb Knight Frank, who represents one of the interested parties but declined to discuss any details or reveal his client.

The prominent food and culinary investor Noam Gottesman, who lives nearby, may have taken a look, but sources close to him insisted he was not one of those setting up shop in the building.

Also in talks for one of the 10,853-square-foot floors is Alibaba Group, the Chinese-based e-tailing giant.

To date, only the healthy living company, Delos, the backers of the WELL Building Standard, is a signed tenant for the fourth and fifth floors.

Sources said asking rents are $180 per square foot for the penthouse, with a range of $130 to $150 a square foot for the rest.
