    What's special

    Discover the pinnacle of modern, luxurious island living! Nestled on just over 3 acres with an impressive 275’ of pristine waterfront on Cow Island, this one-of-a-kind sanctuary offers 4 elegant bedrooms and 2,500 sq. ft. in a seamless blend of privacy, recreation, and sophisticated lake luxury. A private sand beach, expansive dock, and stunning two-slip boathouse deliver an extraordinary waterfront experience. The boathouse boasts oversized doors and two interior slips accommodating 33’ and 22’ vessels, plus space for jet skis and water toys. The exterior dock welcomes docking for two or three more boats. Just steps from the spacious wrap-around deck, an 8-person outdoor hot tub and private hot-and-cold outdoor shower invite relaxation. The entire home was spectacularly interior-designed by Award-Winning Home Comfort, with every piece of custom furniture crafted exclusively for the residence. The indoor dining area seats 8, offers the perfect haven for morning coffee, beautiful dinners, and the adjacent family room is perfect for TV after a day on the water. Outdoor dining from the expansive deck for 12. The fully equipped gourmet kitchen features granite countertops, a large island, elegant slate flooring, stainless steel appliances including dishwasher and washer/dryer. A soaring cathedral-ceilinged living area framed by a wall of windows showcases a spectacular lake view, bringing the outdoors in and opening onto the deck. Warm hardwood floors and a modern Swedish wood stove create a cozy gathering space in every season. The main floor presents a full guest bath and a gorgeous primary suite with full bath; second floor features three generously sized bedrooms plus full bath. A separate queen-sized bedroom cottage sits steps from the shower and hot tub. Fully insulated with a drilled well and electric heat, the home is ideal for year-round enjoyment, wintertime getaways and ice fishing adventures. A rare and spectacular offering among the Islands.
