3D Cooper Hewitt mansion model

The Carnegie Mansion

The Cooper Hewitt main campus is housed in the former home of Andrew Carnegie. The sixty-four-room mansion, built from 1899 to 1902, was designed by the architectural firm of Babb, Cook & Willard in the solidly comfortable style of a Georgian country house. The house is a fascinating study in innovative design. Completed in 1901, it was the first private residence in the United States to have a structural steel frame and one of the first in New York to have a residential Otis passenger elevator.
