In 1998, David Rockefeller engaged D. R. Horne & Company to study the historic farm complex he owned approximately 30 miles north of New York City, and recommend financially sustainable programs of development and use for the 35,000-square foot assemblage of buildings and surrounding agricultural land. Constructed in 1929 by John D. Rockefeller, Jr., this ensemble of buildings had become an iconic expression of the rich history and agricultural heritage of the Hudson Valley.

As developer, DRH led the physical and organizational transformation of the Stone Barns, opened to the public in 2004, into a working organic farm supporting a public agricultural education program, alongside a five-star farm-to-table restaurant (Blue Hill at Stone Barns) and conference facility.
