In the 1790s, John Codman carried out extensive improvements to the original Georgian house and surrounding grounds. Sixty years later, his grandson updated the house in keeping with Victorian taste and filled the house with the finest New York furnishings. Today, the interiors are richly furnished with portraits, memorabilia, and art works collected in Europe, showing the decorative schemes of every era, including those of noted early twentieth-century interior designer Ogden Codman, Jr.
