Modern architecture. Montana scale. Unforgettable views. Completed in 2022 and set on more than 20 acres within Gallatin River Ranch, 94 Rock Castle Road is a striking architectural residence that blends Scandinavian simplicity with alpine-modern warmth. Designed to blur the boundaries between indoors and out, the home pairs floor-to-ceiling windows and natural materials with a highly livable layout. The light-filled main level features the primary bedroom, plus two bedrooms and two full baths, all with 9-foot ceilings. Upstairs, a pavilion-style great room rises beneath a vaulted ceiling opens to east- and west-facing decks with breathtaking 360-degree views of surrounding canyons, ridgelines, mountains, and rolling pastureland. The interiors embrace a sense of quiet luxury—comfortable, intentional, and beautifully restrained. The warm and inviting atmosphere feels equally suited to everyday living or hosting family and friends. A private-entry ADU adds exceptional flexibility, complete with a kitchenette and three-quarter bath. Use it for guests, extended family, an exercise room, detached office, or creative space. The property also includes a two-car garage and a covered carport large enough for a drift boat or small camper. A remarkably productive well provides an exceptional water resource and offers exciting potential for future improvements, subject to applicable approvals. Envision a guesthouse, barn, shop, fenced pastures, or an expanded Montana compound. As a resident of Gallatin River Ranch, you'll enjoy access to approximately 6,000 acres of open space, including access to two renowned rivers, an equestrian center, riverside parks, and more than 20 miles of trails and private roads. Just under three miles from Manhattan and within easy reach of Bozeman and Bozeman Yellowstone International Airport, the property offers something increasingly rare: A beautifully designed home in an extraordinary setting—this is Montana living at its finest. Private showings by appointment.
Welcome to Solstice House. Built in 2022, this architectural residence spans 2,705 square feet and sits on more than 20 acres. Blending Scandinavian and modern design, the line between indoor and outdoor is blurred via floor-to-ceiling windows with natural materials and a highly livable layout. The cozy interiors reflect a “quiet luxury” aesthetic—understated yet refined—prioritizing craftsmanship, comfort, and intentional simplicity. The light-and-airy ground level features three bedrooms and two baths, all with 9-foot ceilings. Upstairs, a pavilion-like great room opens wide beneath a vaulted ceiling, capturing sweeping views of canyons, ridges, and mountains. True to its name, the house aligns with the sunrise on the summer solstice, creating a striking and meaningful architectural moment, especially in the mornings and evenings. 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 an ADU with a private entrance, kitchenette, and three-quarter bath—ideal for guests or flexible use. In addition to the two-car garage, a covered carport 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 additional structures. A guesthouse, barn, shop, fenced pastures--all are encouraged by the development. 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. Call for a showing today!
