    Custom finishesFieldstone terracesGlass-enclosed wine displayWet barHigh-end appliancesGarden shedCoffee and wine bar
    Some homes are built. This one was sculpted. Elevated above the Mianus River with year-round water views, this four-bedroom Greenwich home feels like a private European escape in Cos Cob. Over the past three years, the interiors have been beautifully renovated to match the artistry of the grounds. Enter into a walkout entertainment room, where stonework, a wet bar and fireplace set the tone. Upstairs, sunlit living and dining spaces flow past a glass-enclosed wine display into a chef's kitchen overlooking the river, with high-end appliances, custom finishes, a coffee and wine bar and glass-wrapped window seat for morning coffee. An expansive primary suite with custom closets and renovated bath is complemented by generous en suite bedrooms and a top-level retreat for guests, work or pla 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.
