A rare opportunity to own a truly exceptional family retreat on 5.76 acres of private, tree-lined paradise. Thoughtfully designed and custom built by its owners, this one-of-a-kind estate blends luxury and warmth in equal measure. A place where timeless design meets everyday comfort. From the moment you step inside, the soaring 22-ft foyer and striking floating staircase set the tone for whats to come. Expansive windows flood the home with natural light, seamlessly connecting the indoors with the beauty of the surrounding landscape. Every space here was created with family and connection in mind. The heart of the home is an extraordinary chefs kitchen, anchored by dual islands with seating for 14, top-of-the-line appliances, and effortless flow into the sunroom and outdoor kitchen. Its a space designed for gatherings, where Sunday dinners stretch late into the evening and celebrations spill out under the stars. For everyday indulgence, this estate offers an incredible private spa with a 10-person jacuzzi, steam room, and sauna, plus a home theatre, gym, games area, and full bar. A private elevator adds ease, while a three-bedroom guest suite above the garage provides flexibility for extended family, in-laws, or a live-in nanny. Outdoors, the possibilities are endless. Lounge by the heated saltwater pool, host evenings around one of two fire pits, or enjoy a friendly game on the tennis and basketball courts. Wander along walking paths that circle a peaceful private pond or simply relax in one of the many quiet corners designed for reflection and connection with nature. This estate is as smart and sustainable as it is beautiful, with solar and geothermal systems, full smart-home integration, and two septic systems. This property is designed to stand the test of time and a place to build a legacy. Where laughter echoes through the halls, traditions take root, and generations come together. A lifestyle of luxury, privacy, and possibility awaits. (id:23309)
