Perched atop 20 pristine acres in the forested hills of Towering Pines, this extraordinary custom estate seamlessly blends refined architecture, sophisticated design, and breathtaking natural beauty. Approximately half of the home is a newly built custom addition by OSM, oriented to capture sweeping views of the Spanish Peaks and Lone Mountain. This private sanctuary offers unmatched tranquility, yet is 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 windows, and thoughtful indoor-outdoor transitions flood the home with natural light, highlighting clean lines and elevated finishes. From the moment you enter, curated spaces with custom lighting create a gallery-like ambiance tailored for the discerning collector. Encompassing over 10,000 square feet, the residence accommodates both gracious entertaining and relaxed daily living. Six spacious bedrooms include a primary suite with dual walk-in closets, a private upstairs gym, and a lower-level office and den. A private guest suite with its own kitchen, dining nook, living room, and outdoor sitting deck offers visitors comfort and privacy. Additional highlights include an expanded three-car garage with a beautifully designed mudroom, multiple living areas anchored by striking fireplaces, and a seamless balance of formal and casual spaces. Outside, winding garden paths, quiet seating areas, and sweeping mountain vistas elevate the mountain living experience. Every detail reflects a commitment to timeless design, quality craftsmanship, and graceful living. Ownership also presents the opportunity for a National Membership at Spanish Peaks Mountain Club, one of the Rockies' most exclusive private clubs. This includes access to the Tom Weiskopf–designed championship golf course, a stunning clubhouse with dining, private lift access into Big Sky Resort, and a year-round roster of events. The membership connects owners not only to Spanish Peaks, but also to the broader Montage Big Sky community, offering an unparalleled lifestyle at the heart of one of America's premier resort destinations. A truly rare offering, this estate is more than a home—it is a legacy property, thoughtfully designed to inspire for generations to come.
