To be topped with a modular roof and modular rooftop bar, the world’s tallest modular hotel is expected to open in late 2020 as the AC Hotel New York NoMad. Since the launch of Marriott’s initiative, the company’s development partners in North America have opened 31 Marriott-brand hotels – all low-rise structures – that incorporate prefabricated guestrooms and/or bathrooms, including a Fairfield by Marriott Inn & Suites in Folsom, Calif.; a Courtyard by Marriott in Pullman, Wash., and three AC Hotels in Oklahoma City, Louisville, Ky., and Chapel Hill, N.C.
