Rockefeller Group is a privately held real estate development, ownership, and operating company headquartered in New York City. Founded in 1928 as Metropolitan Square Corporation by John D. Rockefeller Jr., the company originated with the development of Rockefeller Center, the Art Deco complex completed between 1931 and 1939. In 1989, Mitsubishi Estate Co. acquired a majority interest in Rockefeller Group, and today the company operates as a subsidiary of the Mitsubishi Estate Group. Following a 1995 bankruptcy filing, the company restructured and refocused its operations. Rockefeller Group currently owns and manages approximately 6 million square feet of office space in Midtown Manhattan, comprising the western corridor of Rockefeller Center along Sixth Avenue. Through seven regional U.S. development offices, the company maintains approximately 14 million square feet of projects in planning or under construction across multiple asset types, including multifamily residential, industrial and logistics facilities, office buildings, data centers, and mixed-use developments. The company's industrial development platform emphasizes Foreign Trade Zone-enabled facilities, speculative distribution centers, and build-to-suit logistics projects. Its geographic footprint spans 17 states and the District of Columbia, with concentrations in the Northeast, Southeast, Mid-Atlantic, West, Southwest, Rocky Mountain, and North Central regions. Key markets include New York City, Atlanta, Phoenix, Charlotte, Denver, and the greater Washington, D.C. area. Rockefeller Group's multifamily portfolio includes high-rise luxury residential towers in urban centers such as Atlanta, where the company recently completed Alina, a 60-story mixed-use tower.
