Rare opportunity to own an upper-end custom home on one of the most desirable lots in Sun West Ranch, where homes seldom come to market. This thoughtfully designed 4BR/4.5BA residence offers approximately 3,745± square feet and is perched to capture wide-open, unobstructed views across conservation ranchland and surrounding mountain ranges.
An open-concept layout is complemented by a separate living room anchored by an impressive stone, wood-burning fireplace. Mountain-rustic finishes are elevated with dark timber beams, white-washed tongue-and-groove ceilings, and expansive Marvin windows and doors. Two decks and a stamped concrete patio extend living space outdoors, creating a strong connection to the natural surroundings.
The kitchen features GE Café appliances, double ovens, and a gas cooktop. The main level primary suite includes a propane fireplace with a natural Montana stone mantle and stunning views. Two main level guest rooms have private baths. A second primary suite on the lower level provides exceptional privacy. The residence is offered fully furnished with high-quality and custom pieces for immediate enjoyment.
The 4.353-acre lot is covered with mature Douglas fir trees, limbed up for fire prevention and a park-like setting. The property borders ranch open space with nearby access to National Forest and Standard Creek, ensuring permanently protected views and privacy.
Additional features include a finished, insulated, and heated three-bay garage stubbed for EV charging, a 75 SF secure room for valuables, Generac backup power with remote monitoring, fiber optics, on-demand hot water, water filtration, oversized cistern, underground irrigation, and monitored security and alarm systems.
Sun West Ranch is a gated 2,000-acre community with approximately 1,600 acres of open space, two miles of Madison River frontage, stocked ponds, and equestrian amenities. Homes may be used as vacation rentals between May and October. Conveniently located near Yellowstone National Park, Big Sky Resort, and regional and private air access.
