It combines a mansard-roofed house of 1866 with a large shingle-and-stone addition designed by Henry Hobson Richardson between 1884 and 1886.","why_significant":"The nomination argues the house is significant as the work of architect H. H. Richardson, whose interior is considered his finest surviving domestic one, and as the home of philanthropist Robert Treat Paine Jr. The landscaping is by Frederick Law Olmsted. The estate is also one of three surviving estates in a densely populated, industrial city.","narrative":"Stonehurst, the Robert Treat Paine Jr. House, sits at the center of a wooded 113-acre park in Waltham, Massachusetts, out of view from the street and reached by a quarter-mile drive. It has two parts: a clapboard mansard-roofed house of 1866 and a much larger addition designed by Henry Hobson Richardson between 1884 and 1886. The addition has boulder-faced first-story walls, shingled upper floors, three flat towers and a Great Hall with a famous staircase. Frederick Law Olmsted selected the site and designed the landscaping. Robert Treat Paine Jr., a classmate of Richardson and a leading philanthropist, lived here. He promoted cooperative banks and housing for the poor and served as first president of the American Peace Society. The interior is regarded as Richardson's finest surviving domestic work, and much of the original furniture and library remains. Paine's grandson gave the house and park to the City of Waltham in 1974.","period_of_significance":"1800-1899","architect_builder":"unknown (earlier house); H. H.
