Iconic Mid-Century Modern tri-level Techbuilt home, constructed in redwood and glass, and privately tucked away on a sloping wooded acre with direct access to the Old Erie Rail trail and just 15 miles from NYC. Vaulted ceilings and exposed beams, create open sunny spaces with glass walls, multiple decks and oversized sliders that bring the outdoors right in. Bask deeply in nature among the canopies of mature trees, and take in the seasonal Hudson River views. Intentionally designed "upside down", with the bedrooms below the main living areas, to best capture views and maximize privacy. Enter on the main level with a circular floor plan of kitchen, dining room, and living room, anchored by a brick wood-burning fireplace to cozy up to during the winter months. A half bath plus a versatile office or guest room, are also on this main level. The stairway down to the second level leads you to 3 bedrooms, & 2 full baths, including a primary suite with it's own private deck, walk-in closet, and en suite bath. Everyone wakes up to wooded views from all the bedrooms. Walk past a back laundry area and down to a finished ample walkout lower level for added practical extra space for recreation or storage. 2- car carport to protect from the elements. You'll enjoy both privacy and easy access to Nyack and Piermont Villages. A great opportunity to own a vintage modern architectural gem just minutes from NYC, where classic design meets modern convenience in a truly serene setting. Note: This property is adjacent to and currently owned together with 903 Route 9W S (MLS # 907046) a vacant parcel that can be sold together, for additional privacy or expanded development opportunities.
