Private Beach • Waterfront • Renovated Yr-Round Home • Efficient Layout • Turnkey Tranquility At the end of a private half-mile paved drive, this fully renovated Cape Cod-style ranch offers rare privacy on a Great Pond--a crystal-clear, spring-fed 83-acre pond with fewer than a dozen homes on its shoreline. Enjoy your own sandy beach and stunning westerly sunsets from nearly every room. Set on almost 1/2 an acre, this yr-round home features a designer kitchen with quartz counters, SS professional appliances, and a dual-fuel range. The spa-style bath includes a 7-foot glass/tile shower with jets and a heated backlit mirror. Vaulted ceilings, reclaimed wood accents, & a wood stove create a cozy yet upscale vibe. Modern updates--new roof, siding, luxury vinyl floors, energy-efficient systems, and custom finishes--make this a low-maintenance retreat. With a walk-in closet, laundry room, and sweeping lake views, it's the perfect blend of comfort and elegance. A truly rare waterfront retreat
