Although reachable by Route 25A, this 1915 Gold Coast estate in Upper Brookville overlooks 35 acres of privately owned land.
"The most special thing about the house is that no one knows it's there," according to listing agent Katherine Cuddeback of Daniel Gale Associates. "It's totally private."
Built of fieldstone with a slate roof, the home boasts quite a pedigree: It was built by architect Montague Flagg, who designed the Bankers Trust Company Building and the Thomas Cook Building in Manhattan. The gardens were designed by Annette Hoyt Flanders, a landscape architect who created the Classic Modern Gardens at New York's 1939 World's Fair.
Listed at $8.95 million, the home has 8 bedrooms, 8.5 bathrooms, 7 fireplaces, a 1,000-bottle wine closet and walk-in safe.
Outside, there is a tennis court, heated gunnite pool and 10,000 tulips that explode in color come spring.
