Marriott has revealed plans for a new New York City project: the world’s tallest modular hotel. Branded as an AC Hotel, the development will be a 360-foot stacked tower featuring a prefabricated roof and a rooftop bar.
“In North America, the construction process hasn’t changed significantly in 150 years and it’s ripe for innovation,” said Eric Jacobs, chief development officer for Marriott International’s North America Select and Extended Stay brands. “The world’s tallest modular hotel in one of the world’s greatest destinations will act as a game-changing symbol to ignite even greater interest in modular among the real estate and lending industries.”
The project relies on prefabricated guestrooms delivered to the site fully finished and furnished, with items ranging from flooring to toiletries already in place. The roof and rooftop bar are also constructed off-site and installed complete. Using prefabricated modules speeds construction, reduces waste and minimizes on-site noise compared with traditional building methods.
“This hotel takes every advantage of off-site manufacturing, as you might expect. But it does so in a way that defies expectation. We wanted to demonstrate that modular building can do more than just harness the efficiencies of the factory. It can produce a graceful and iconic tower. And yes, it can do so at the rate of an entire floor a day,” said Danny Forster, a leading advocate and designer of modular construction.
By integrating modular construction techniques with a high-profile urban landmark, Marriott aims to showcase the potential of factory-built methods for large-scale projects. The approach promises faster delivery timelines and improved quality control, since much of the work is completed under controlled factory conditions. It also offers environmental benefits through decreased material waste and fewer deliveries to the jobsite.
For developers and lenders, the project serves as an example of how modern construction strategies can address persistent industry challenges: schedule risk, labor shortages and rising costs. If the AC Hotel tower meets expectations, it could encourage broader adoption of modular practices across commercial real estate and hospitality sectors.
For guests, the modular approach should translate into consistent room finishes and a streamlined opening process. For the surrounding neighborhood, faster construction and reduced site disruption are tangible advantages. In combination, these factors position the project as a test case for how modular design can be scaled to create striking, functional buildings in dense urban cores.
Marriott’s New York modular hotel represents a notable shift in how major hotel brands can approach development—blending design ambition with industrial efficiency to create a prominent new destination in the city’s skyline.
