Arden House Rd, Harriman, NY 10926
Arden house is one of the largest homes in the United States. It is almost 100,000 square feet.
Arden was the estate owned by railroad magnate Edward Henry Harriman and Mary Averell Harriman outside Harriman, New York. On September 17, 1886, Harriman bought at auction the 7,863-acre Peter Parrott family estate for $52,500, which was named Arden by the Parrott family after Mrs. Parrott’s maiden name. Harriman hired Carrère and Hastings to design a home, which was begun in 1905. Harriman commissioned a number of American artists to decorate the house. James Earle Fraser did a bas-relief portrait of Harriman over one of the fireplaces, as well as a fountain in the interior court; Malvina Hoffman did a bust of Mrs. Harriman; and Charles Cary Rumsey did a fountain of the Three Graces, a marble fireplace surround that featured a caricature of architect Thomas Hastings, and corbel carvings of bighorn sheep in the music room. On the second floor was an “Indian Corridor,” featuring photographs of Native Americans taken by Edward S. Curtis during the Harriman Expedition of 1899. Harriman’s widow gave the house to her son W. Averell Harriman upon his wedding in 1915, although she continued to live in the west wing of the building until her death in 1932. In 1950, Averell Harriman and his brother Roland deeded the property to Columbia University, as “Home of The American Assembly”, a public policy institution founded by Dwight D. Eisenhower the same year.
