In 1930, with the retail trade in New York City moving uptown, the store moved again, this time to a new address on Fifth Avenue. Bonwit took up residence in the former Stewart & Co. building at Fifty-sixth Street, which would remain the company's flagship store for nearly fifty years. The building had been designed by the architectural firm Warren and Wetmore in 1929 and redesigned the next year by Ely Jacques Kahn for Bonwit.
