The "Tip Top Tap" sign under the building's peak was kept as a historical artifact, even though the bar on top of the hotel has been long closed.
The architects based the hotel on their design for Barbizon/63 in New York City.
The setback at the top was required by a 1923 zoning law.
The entire hotel underwent a $50 million renovation in the 1990s intended to restore the original Northern Italian Renaissance style. As part of this renovation, the hotel was renamed the Allerton Crowne Plaza.
The main lounge was inspired by the long gallery in Hever Castle in Kent, England.
The hotel was built as part of a chain of houses for single professionals. Consistent with the times, it reserved 14 floors for men and 6 for women. The men's floors are women's floors were serviced by different elevators.
