The original building is an 18-storey Beaux Arts style building with heavy baroque-esque ornamentation and a faux-mansard roof. Designed by the firm of Trowbridge & Livingston, it was the tallest hotel in the city when construction completed in 1904. The building was made a NYC Landmark in 1965.
The original interiors were by Arnold Constable, but much of those have been since entirely revamped. In fact, a series of interiors with luxury sponsorship were commissioned in the past couple of years. Tiffany, Dior, and Bentley are the first three to provide themed suites, with the latter providing access to the first 2013 Bentley Muslanne in the United States.
