One of a kind, sophisticated Mid Century Modern home built with a unique blend of steel and stone aggregate. Designed by award-winning architect Arthur Witthoefft of Skidmore, Owings & Merrill, 9 Tallwoods has been meticulously maintained and now offered for sale for only the second time in 52 years. A statement of contemporary luxury living at its finest, nestled in the woods, this home merges indoor living with an outdoor ambience as walls of glass, a floating wrap-around terrace and a 20' domed atrium allow sunlight to stream seamlessly throughout. An open floor plan hubs around the original circular fireplace, while elegant Leicht cabinetry with state-of-the art appliances create the perfect chef's venue. The primary suite with floor-to-ceiling glass doors to the terrace and a zen-like bath with dual sinks, a Japanese soaking tub and a steam shower offers a serene getaway. Two ensuite bedrooms also access the terrace. The lower level with an expansive, open recreation room is accessed by the architectural, winding staircase. A resplendent guest suite offering an additional bedroom and adjacent living room is ideal for a live-in au-pair or guests. A fifth ensuite bedroom completes the main house. Across the heated driveway is a separate three car garage with clean and sleek lines. Located in Armonk, NY, close to highways and trains and a 45-minute commute to NYC. This is a rare opportunity for the MCM enthusiast.
