Welcome to Solstice House! Built in 2022, this architectural home offers 2,705 square-feet with an ADU, located on 20+ acres with ample room for a guest house, a barn or shop, fenced pasture, and more. This home was designed in the style of Northwest Modernism, popular since the midcentury for its floor-to-ceiling windows, connection to Nature, high livability, natural materials, and clean lines. Evocative of Scandinavian living, the interiors hit the mark for 2026’s trend of “quiet luxury,” emphasizing high-end homes of reasonable scale with meaningful details, a simplified lifestyle, and understated comfort. Three bedrooms and two baths–all with 9′ ceilings–comprise the ground level, while the pavilion-like upper level presents a grand living area with a vaulted ceiling and 360-degree panoramic views. One unique characteristic is the alignment of the primary ridge and great room with sunrise on the summer solstice, giving the house its name. A large deck and patio elevate the indoor/outdoor experience while horses graze in the surrounding hills, buttes and ridges replete with wildlife, and Big Sky sunsets. It’s a tranquil place where evenings feel like weekends and weekends feel like escapes. In support of the primary home, there’s an ADU with a private entrance, covered parking for a drift boat or small camper, the well log records an astounding 100 gallons per minute, and the setting offers outdoor access in every direction. From the very first day, the intent was to surpass the new objectives for a 21st-Century home. Sustainability is embodied by an array of natural and time-proven materials, the energy-conserving layout, appliances, and fixtures, exterior material selection and planning to diminish wildfire risks, off-grid water treatment and a highly productive water source for living, landscaping, and gardening, solar-ready roof and wiring path, and an enduring structural frame that sets this home up for many generations of comfortable living. Located in Gallatin River Ranch, the vast 6,000-acre development is lifestyle-enhancing with two famous rivers, an impressive Equestrian Center, two riverside parks, and over 20 miles of private roads and trails great for hiking and biking. Less than three miles from charming Manhattan, Mont., Solstice House is a 20-minute drive from the airport and 30 minutes to Bozeman’s growing amenities.
