Everything stays on the other side. That is what people here say about the footbridge. You cross it, and whatever you were carrying does not come with you. Compo Mill Cove is a gated private peninsula of nineteen homes on Long Island Sound, and no car has come out here since 1903. It is the reason the loudest thing you hear most mornings is the tide turning under the bridge. Everyone in this town is trying to buy quiet. Out here it is structural. This is the one with the water in every room: 5,567 SF of Brooke Girty-designed shingle style, built in 2008 and laid out so the Sound is never more than a glance away. Century-old reclaimed French oak floors. A three-story Nautilus stair through the center of the house. Five fireplaces. A Viking and SubZero kitchen. A primary suite with its own fireplace, dual walk-ins and a balcony above the water. Four bedrooms, generously scaled, plus a full third floor for guests, a studio or an office. Then the part you actually live in. A screened porch for the mornings. A Brazilian hardwood deck and hot tub for the evenings. Your own sandy beach with a kayak pulled up on it, held by a Race Coastal-engineered bulkhead. A private gate opening into the protected shoreline and woodland of Sherwood Island State Park. Green's Farms station minutes away, Manhattan about an hour. Nineteen homes. There will not be a twentieth. Your car is 150 feet away. You will not want it.
