Rare custom home from 2019 on 3.27 acres in Big Sky with a true single story layout and a separate one bedroom ADU. The property backs to open space with no neighbor behind, so you get privacy, views, and room to breathe. Designed and built by the current owners, the main residence has four bedrooms and five baths. Every bedroom has its own custom walk in closet. A bonus room with a fireplace and closet works beautifully as an office, den, or optional fifth bedroom. Finishes include rich hardwood floors, vaulted ceilings, crown molding, and an easy flow from the formal dining room and butlers pantry to the great room with a stacked stone fireplace and tri fold doors that open for true indoor and outdoor living. The chefs kitchen brings high end appliances, an oversized island, farmhouse sink, and a walk in pantry. The mud and laundry room adds built ins and a sink. Step outside to a resort style pool and spa, vegetable and herb garden, and multiple fruit trees. The acreage is usable and wide open, with space to expand the orchard or explore another ADU opportunity subject to buyer verification. The lot backs to open space with no rear neighbors, so you get quiet mornings, big sky sunsets, and a backyard that feels like your own private park. Over the detached three car garage sits a beautifully finished ADU with one bedroom and one bath, a full kitchen, in unit laundry, separate AC, tankless water heater, private entrance, and sweeping views. It is ideal for multigenerational living, a guest retreat, or rental income. A full bath in the garage opens toward the backyard for convenient pool access. You are tucked away in Winstone, minutes to shopping, dining, trails, and freeway access. With a custom build, a true single story layout, a legal ADU, no neighbor behind, and room to grow an orchard or explore additional ADU possibilities, this property stands out in Big Sky.
