This 27-story building at 90 Washington Street was erected as an office building in 1970 by the Sylvan Lawrence Company and was converted to rental apartments by the Moinian Group in 2003.

The building is also known as 23-31 Rector Street and 52-54 West Street. It is across West Street from Battery Park City.

The building has 398 apartments and a setback at the 13th floor on West Street.

It was the first residential project to receive Liberty Bond financing through the New York City Housing Development Corporation.

For many years it has been used as offices by the Bank of New York.

The building, which is known now as 90W, has a walnut-paneled attended lobby and its apartments have ceilings that range in height from 10 to 13 feet and broad windows.

It has a fitness center, and Club 90, a 12,000-square-foot event center with a residents lounge, billiards, a landscaped roof deck, an outdoor golf putting green, and a landscaped outdoor plaza with a waterfall.

The Moinian Group, which is headed by Joseph Moinian, also converted the former Downtown Athletic Club building nearby at 20 West Street and is the developer of the W Hotel nearby at 123 Washington Street,

A New York Times article by Alison Gregor May 21, 2006 reported that Mr. Moinian arrived in the United States from Iran in 1971 at the age of 16. He studied at City College and his first venture was an apparel company called Billy Jack for Her.

In 1996, he developed the Biltmore residential tower at 271 West 47th Street and the Marc at 260 West 54th Street and in 2008 opened the Atelier at 627 West 42nd Street.

The Times article said that "Mr. Moinian's business dealings haven't been without conflict," noting that he had been sued by some residents who had moved into 90 Washington Street and had complained about non-working elevators and faulty heating that led to extensive flooding. "Mr. Moinian said that in order to honor agreements with tenants he had allowed them to move into the apartments before all the work had been completed," the article said, adding that Mr. Moinian "eventually settled with the tenants giving them two months' free rent and fixing the building's problems."
