    What's special

    Sheltered deck dining areaSoaring vaulted ceilingUnexpected curved balconyExpose the dynamic viewsSerene outdoor oasisOpen staircaseZen like landscaping
    Tucked away, 70 Third Street feels both private and unexpectedly special, where thoughtful details have been purposely placed throughout the grounds and the house itself. Zen like landscaping surrounds this contemporary creating a serene outdoor oasis while offering sweeping views of the Atlantic Ocean. Placement of windows and french doors not only expose the dynamic views but also invite the outside in. An amazing chef's kitchen features windows that open directly onto a sheltered deck dining area, while the lving room is anchored by a dramatic floor-to-ceiling fireplace that becomes a striking focal point. A soaring vaulted ceiling opens to the second floor, enhancing the home's sense of volume and architectural interest, where an open staircase reveals an unexpected curved balcony that adds a distinctive design element.The primary suite encompasses the entire second floor and includes a comfortable sitting area along with a private deck for a quiet retreat, while two lower bedrooms enjoy direct access to a peaceful courtyard offering the ever-present connection to nature. Adding to the property's rare waterfront appeal, a private dock offers direct access to the tidal inlet leading to the tranquil "let" portion of the Westport River, making this a truly unique coastal retreat.
