Over the years, the building underwent renovations, most recently in 2018. It is known for its unobstructed views of the High Line and its strategic location, attracting various investments and tenants.

Recently, Robert Moser's Prime Group and Empire Capital Holdings acquired the property for $50 million, aiming to convert it into self-storage and office space after the departure of major tenant WeWork.
