After years of disrepair, by the 1990’s, the top 4 story top cupola was so deteriorated that it was eventually demolished. In 2000, Masterworks Development Corporation acquired the structure and undertook a multiyear complete renovation.
The lower portion of the building currently houses the River Hotel. The octagonal upper stories are currently occupied by Club Quarters–a chain of membership corporate accommodations.
