Off-the-Charts Cool, Cool, Cool. This Mid Century Modern architectural masterpiece is tucked away on 8.6 Hudson Valley acres, blending seamlessly with nature through floor-to-ceiling windows. About one hour north of NYC in Westchester County, "The Mothership" Roundhouse is a stunning MCM structure designed and built by Robert Cika under the commission of American Icon Jackie Gleason who was fascinated by UFO's. Completed in 1959, the home was under construction for 5 years. A second "Spaceship" is a smaller structure that has been used as a bunk-house and glamping over the years. It is as if Spaceships have landed in the woods of Westchester! The detailed, extraordinary craftsmanship is evident in the woodworking, almost entirely bent, a process which is a time-consuming art. A Scandanavian shipbuilder was commissioned to create the ceiling design which resembles the shape of boats while the metal work is also incredible - some vents resemble stylized fish. Floors and fireplaces are made of Italian marble. (Gleason was said to have purchased an entire marble quarry in Italy to ensure the ability to import enough quality marble!) There is much folklore that surrounds this property too - if the walls could talk. Gleason's celebrity guests are fabled to have included Frank Sinatra, Marilyn Monroe, Joe DiMaggio and Nixon for his midnight soirees. With the original swooping Bars (3), a Game Room (with official Shuffleboard table) and the glamorous Marble Dance Floor, this home was imagined for entertaining. Yet "The Mothership" is also relaxing and one enjoys beautiful views and a harmonious connection with Nature provided by the floor-to ceiling windows. Other features: Three Bedrooms, two Full baths, one Half Bath, Stainless Steel Curved Kitchen, spacious Livingroom Area, Dining Room, circular Library and Office. It is remarkable that many original details and numerous built-in cabinetry and closets have been preserved. Additionally, "The Barracks," a 1930's Stone Colonial House is charming and can serve as a guest house. Plus, lovingly cultivated and fully fenced expansive vegetable and herb garden with gardening shed. An exceptional private country estate retreat, this property is a hidden gem. Close to championship Golf Courses, the Hudson River, West Point, Dining, Shopping, Music and Metro North Train Stations for convenience. Simply put, "How sweet it is." © 2025 OneKey™ MLS, LLC
