Rare 2019 custom build on 3.27 acres in Big Sky—one of the neighborhood’s few custom-lot, single-story estates— with a separate 1-bed ADU. Designed and built by the current owners, the main residence offers 4 bedrooms / 5 baths, each bedroom with its own en-suite plus custom walk-in closets. Additionally, a versatile bonus room with a fireplace and closet works perfectly as an office, den, or optional 5th bedroom. Rich hardwood floors, vaulted ceilings, crown molding, and an open flow from formal dining & butler’s pantry to the great room with stacked-stone fireplace and tri-fold doors for true indoor/outdoor living. The chef’s kitchen features high-end appliances, oversized island, farmhouse sink, and walk-in pantry. Mud/laundry room with built-ins and sink. Outdoors: resort pool & spa, vegetable/herb garden, multiple fruit trees—backing to open space with no rear neighbors. Over the detached 3-car garage sits a beautifully upgraded true ADU (1 bed/1 bath) with full kitchen, in-unit laundry, separate A/C, tankless water heater, private entrance, and sweeping views—ideal for multigenerational living or rental income. A full bath in the garage opens toward the backyard for convenient pool access. With expansive, usable acreage that may allow additional ADU possibilities and a tucked-away location minutes to shopping, dining, and freeway access, this is a standout opportunity among Big Sky customs.
