Fieldston is a privately owned affluent neighborhood in the Riverdale section of the northwestern part of the New York City borough of the Bronx. It is bounded by Manhattan College Parkway to the south, Henry Hudson Parkway to the west, 250th Street to the north, and Broadway to the east. It is noted for its rural atmosphere, large houses and abundance of trees. The majority of the neighborhood is included in the Fieldston Historic District, designated by the New York City Landmarks Preservation Commission in 2006. One of New York City’s most upscale neighborhoods, Fieldston is home to two of the three prestigious "Hill Schools", the Horace Mann School and the Ethical Culture Fieldston School; the third, Riverdale Country School, lies just outside Fieldston to the north. Manhattan College is located on Manhattan College Parkway, the neighborhood's southern boundary. History The land that is now Fieldston was part of the estate of Major Joseph Delafield, who purchased in 1829, and named it after his family's estate in Ireland. The Delafield family laid out lots in 1909 – the year after the New York City Subway's Broadway–Seventh Avenue line was extended to Van Cortlandt Park, intending to develop the land, which at first was called "Delafield Woods". Rather than use a grid plan, civil engineer Albert E. Wheeler, following the suggestions made by Frederick Law Olmsted and James R. Croes in 1876, designed a street plan which followed the contours of the land and preserved as much of the wooded areas as possible. The first house was begun in 1910 and finished in 1911. In 1923, after the completion of 80 houses, the Fieldston Property Owner's Association was formed. Buyers were provided with a list of approved architects, and historicist architectural styles – the various "revival" styles – were strongly encouraged. The Tudor revival style was popular in houses built in the 1920s; many of them were designed by local resident Dwight James Baum, who was responsible for 62 houses, while Julius Gregory is credited with forty-two. Many of the houses in the neighborhood were featured in design and architectural magazines, and the neighborhood had a reputation for having houses of quality design. In order to accommodate the project's plan to be a neighborhood of single-family dwellings, the New York City Planning Commission approved a special zoning district in 1938, which would not allow the construction of any multiple-family buildings.
