Dodge House, is a two-and-a-half-story masonry residence in Riverdale, the Bronx, set on a hill above the Hudson River. Built in 1863-64 as a summer home for philanthropist William E. Dodge Jr. and his family, it was substantially enlarged in 1892 to serve as a year-round suburban residence. Its Tudor/Gothic design features an informal arrangement of masses, many gables and dormers, original patterned colored slate roofing, and simple Gothic detail such as trefoils, quatrefoils and mullioned windows. The design and enlargement are attributed to James Renwick Jr., a family friend and frequent architectural consultant. The house reflects Riverdale's growth as a retreat for prosperous New York merchants and the preservation of its villa character. Dodge's daughter Grace Hoadley Dodge was connected to the founding of Teachers College, which received the house as a gift in 1961 and opened it as a conference center in 1963.","period_of_significance":"1800-1899","architect_builder":"Attrib.
