One of the tallest Hyatt hotels in the country, with 46 floors and over 500 rooms, it offers sweeping city views to the north and south, including the Empire State Building and Freedom Tower. This 45-story hotel rising from New York’s Chelsea neighborhood can be seen from miles away as it rises above the neighboring buildings. With such prominent exposure on all 4 sides, the design required a natural stone exterior to anchor it to the surrounding context. Additionally, the façade was required to have all external cladding and insulating layers within a total system depth of 4 ”, while having a certain depth to account for tolerances on a very tall concrete superstructure.
