Escape the ordinary. 316 Valley Road offers an increasingly rare combination of sweeping water views, absolute privacy, and uncompromised convenience. Sculpted by the former head designer of the New York Botanical Garden, the estate's multi-level stone terraces, mature gardens, and all-season stone gazebo create a breathtaking backdrop. The completely reimagined, turnkey interior boasts exceptional craftsmanship, including rich hardwood floors and quality moldings throughout. A thoughtful layout features versatile living spaces, a chef's kitchen, a dramatic family room, and luxurious ensuite bedrooms. Situated a mere five minutes from the train and a short walk to schools, this home stands aside from the standard formula to deliver a truly unique lifestyle. Life moves outside through the kitchen's French doors to a two-level stone patio, where a waterfall, stone fire pit and dining area invite long evenings with friends. Beyond it, hidden garden paths, fieldstone terraces and outdoor rooms created by the former head designer of the New York Botanical Garden unfold across the property. Follow the paths to a covered stone grotto with fireplace -- perfect for wine and cheese by the fire on cool evenings -- a garden shed and hillside tower overlooking the property.
Walk to schools, the neighborhood deli and wine shop, launch a kayak across the street, or reach Metro-North in five minutes. This is not simply a house you see. It is one you feel.
