About this home

Find your ultimate sanctuary on 4.73 acres of pure tranquility with your very own Golden Lake. The centerpiece of this meticulously maintained estate is a spectacular, spring-fed private lake—approximately one acre —stocked with largemouth bass, catfish, and vegetarian carp, offering a year-round haven for boating, fishing, and ice skating. Decoratively designed Unilock driveway and walkways guide you past mature trees, vibrant perennials, and manicured lakeside lawns to this freshly painted three-bedroom, four-bathroom Colonial masterpiece. Inside, the main level with 9 foot ceilings features a grand two story entrance, an inviting eat-in kitchen and a cozy family room with a fireplace. Dual patio doors open seamlessly to an expansive Trex wrap around deck and rear patio, a fenced garden, a custom checkerboard patio, and a park-like swing set perfect for entertaining and gatherings. The striking formal living room boasts a dramatic architectural turret, offering a sweeping 225-degree panoramic view of the water. Upstairs, the primary suite serves as a private retreat, complete with a turret, ensuite bath and walk-in closet, complemented by two additional bedrooms, a full bath, and a dedicated laundry area. The walkout lower level is an entertainer’s dream, with over an additional 1,096 square feet featuring soaring 9 foot ceilings, a media room, an exercise room, and a recreation space with a wet bar hookup and full bath—all stepping straight out to the lake. An oversized two-car garage features bonus overhead storage. Complete with a walkable woodland path, this rare, one-of-a-kind property is the perfect primary residence or weekend getaway. Your slice of peace awaits.
