Perched atop 20 pristine acres in the forested hills of Towering Pines, this extraordinary custom estate is a rare opportunity to own a residence that seamlessly blends refined architecture, sophisticated design, and breathtaking natural beauty. Approximately half of the home is a newly built custom addition, expertly crafted by OSM--seamlessly integrated into a landscape of mature pines and oriented to capture sweeping views of the Spanish Peaks and Lone Mountain. This private sanctuary offers unmatched tranquility, yet is conveniently located just minutes from Big Sky's world-renowned ski resort, championship golf, the Blue Ribbon waters of the Gallatin River, and the vibrant Town Center. Inside, soaring ceilings, expansive picture windows, and thoughtful indoor-outdoor transitions flood the home with natural light, illuminating the clean lines and elevated finishes that define the architecture. From the moment you enter, you are immersed in curated spaces enhanced by custom lighting throughout, creating a gallery-like ambiance tailored for the discerning art collector. Floor-to-ceiling windows, dramatic walls, and illuminated niches provide the ideal backdrop for showcasing fine art. Encompassing over 10,000 square feet, the residence was meticulously crafted to accommodate both gracious entertaining and relaxed daily living. The home features six spacious and elegantly appointed bedrooms, including a primary suite with dual walk-in closets, a private upstairs gym, and a lower-level office and den offering a quiet retreat. An attached private guest suite serves as a fully self-contained haven with its own bedroom, bathroom, kitchen, dining nook, and living room, opening to a private outdoor sitting deck. Ideal for hosting visitors with both comfort and privacy. Additional highlights include an expanded three-car garage, steps from a beautifully designed mudroom that combines functionality and luxury to suit every outdoor lifestyle. Multiple formal and informal living areas, anchored by striking fireplaces, create intimate gathering spaces throughout. Outside, winding garden paths, quiet seating areas, and sweeping views of the surrounding peaks elevate the mountain living experience. Every detail of this home reflects an unwavering commitment to timeless design, quality craftsmanship, and graceful living in the Montana mountains. A truly rare offering- it is a legacy estate, thoughtfully designed to inspire for generations to come.
