Welcome to Solstice House. Built in 2022, this architectural residence spans 2,705 square feet and sits on more than 20 acres, offering room for a future guest house, barn, or shop, along with fenced pastures and wide-open space. Blending Scandinavian and modern design, the home connects seamlessly to its surroundings through floor-to-ceiling windows, natural materials, clean lines, and a highly livable layout. The interiors reflect a “quiet luxury” aesthetic—understated yet refined—prioritizing craftsmanship, comfort, and intentional simplicity.

The ground level features three bedrooms and two baths, all with 9-foot ceilings. Upstairs, a pavilion-like great room opens beneath a vaulted ceiling, capturing sweeping 360-degree views. True to its name, the home’s primary ridge and great room align with the sunrise on the summer solstice, creating a striking and meaningful architectural moment. Expansive decking and patio spaces enhance indoor-outdoor living, overlooking rolling hills where horses graze, with buttes, ridgelines, abundant wildlife, and unforgettable Big Sky sunsets as the backdrop. It’s a setting where evenings feel like weekends and weekends feel like a true escape.

Complementing the main residence is a detached ADU with a private entrance, kitchenette, and three-quarter bath—ideal for guests or flexible use. A covered parking area adjacent to the garage accommodates a drift boat or small camper. The property is supported by a remarkably productive well (recorded at 100 gallons per minute) more than enough for any residential use or future improvement.

Located within Gallatin River Ranch—a 6,000-acre community offering private access to two renowned rivers, an equestrian center, riverside parks, and more than 20 miles of trails and roads—Solstice House combines privacy, great design, and recreation. Just under three miles from Manhattan, Montana, and within easy reach of Bozeman and BZN airport, the location offers both seclusion and convenience.
