94 Rock Castle Road Welcome to Solstice House! Built in 2022, this architectural home offers 2, 705 square-feet with an ADU, and it's well placed on 20+ acres with ample room for a guest house, a barn or shop, 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 the outdoors, high livability, natural materials, and clean lines. The design is also on the mark for 2026's trend of "quiet luxury, " emphasizing smaller, high-end homes with meaningful features and understated comfort. Three bedrooms and two baths with 9' ceilings comprise the ground level, while the pavilion-like upper level presents a grand living area with 360-degree views and a vaulted ceiling. The primary architectural gesture is the alignment of the great room with sunrise on the summer solstice, giving the house its name. With a large deck and patio to elevate the indoor/outdoor experience, horses grazing in the surrounding hills, buttes and ridges replete with wildlife, 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. 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.
