Driving Directions

Every day at 45 Seth Lane feels like a vacation, where mornings rise with the tide and dawn paints soft light across Bass River. Set on 1.37 acres of vibrant gardens and green space with 288 feet of private river frontage, this 5-bedroom, 5.5-bath estate blends Cape Cod charm with modern comfort, with nearly every room intentionally designed to capture panoramic water views. The sunlit river room and first-floor primary suite with a new radiant-floor spa bath offer restful retreats, while updates-including a new Jack & Jill bath upstairs, a new main-level full bath, and central air-enhance daily living. From the licensed dock with water and electricity, enjoy mornings of kayaking, paddleboarding, or head out by boat to Nantucket Sound. Afternoons invite barefoot walks on the lawn, reading on the deck, or quiet reflection. Loved for its serenity and beauty, this rare waterfront estate offers more than a home-it is an enduring retreat into the timeless beauty of Cape Cod.
