The Nelson-Atkins Museum of Art, already acclaimed for its encyclopedic collection, has earned acclaim for striking additions and improvements to its facility. The creation of galleries for the American and American Indian collections on the museum’s second floor was no exception. The renovation included the total overhaul of the existing historic galleries, expansion of the space from 8,000 to 13,000 square feet. Working in such a small space with limited access encouraged McCownGordon to think creatively. With no windows on the second floor, the team briefly opened up the museum’s roof to fly in the air-handling unit by helicopter. The project team upgraded outdated mechanical equipment and finished the space with the finest materials, including Israel Graige stone flooring and bathroom partitions, Etruscan Rose stone columns, and wood flooring.
