The Hyatt Grand Central New York is a hotel located at 125 East 42nd Street, adjoining Grand Central Terminal, in the Midtown Manhattan neighborhood of New York City. It operated as the 2,000-room Commodore Hotel between 1919 and 1976. Hotel chain Hyatt and real estate developer Donald Trump converted the hotel to the 1,400-room Grand Hyatt New York between 1978 and 1980, encasing the facade in glass and renovating the interior. , the hotel is planned to be replaced with a skyscraper named Project Commodore after 2023. The New York Central Railroad had acquired the site in 1910 and started constructing the hotel in October 1916. The Commodore was designed by Warren & Wetmore, with the Fuller Company as the hotel's general contractor. The hotel was either 26 or 28 stories high and had an "H"-shaped floor plan and a brick-and-terracotta facade. It contained a large lobby designed in a manner resembling an Italian courtyard, as well as various dining rooms and ballrooms. The Commodore opened on January 28, 1919, and was originally operated by Bowman-Biltmore Hotels. Zeckendorf Hotels took over the Commodore's operation in 1958 before handing it to New York Central subsidiary Realty Hotels in 1966. Due to declining profits, the Commodore closed on May 18, 1976. Trump and Hyatt offered in 1975 to take over the Commodore and renovate it into the Grand Hyatt. After the city government granted a tax abatement for the renovation, Trump and Hyatt completely remodeled the hotel from June 1978 to September 1980, spending $100 million and removing almost all of the Commodore's original decorations. The renovated hotel includes a glass facade, a three-story atrium, a restaurant cantilevered over a sidewalk, and the Commodore's original ballroom. Trump and Hyatt's partnership deteriorated during the early 1990s, and the Pritzker family, which operated the Grand Hyatt, acquired Trump's stake in the hotel in 1996. Hyatt renovated the hotel in the late 1990s and again in the early 2010s. The Project Commodore skyscraper was announced for the site in 2019, and the Grand Hyatt closed in 2020 during the COVID-19 pandemic in New York City. The hotel reopened in 2021 as the Hyatt Grand Central, although the hotel is scheduled to close permanently after 2023.
