This unique 20-acre +/- off-grid homestead offers privacy, tranquility, and a front-row seat to the natural beauty of Montana’s wilderness. Surrounded by towering trees, open meadows, and dramatic rock outcroppings, this secluded haven offers a rare blend of peace, beauty, and untapped potential—awaiting your finishing touches.
At the heart of the property lies a solid foundation for your dream home: a poured 30x74 concrete base with insulated concrete form (ICF) stem walls, a 10-foot front porch, a 10-gallon-per-minute well supported by a 500-gallon cistern, and a 2,500-gallon septic system already in place. This is a blank canvas for your vision, whether it's a rustic retreat or a modern homestead.
The property includes a 30x40 all-metal shop designed with versatility in mind. Featuring a 14-foot ceiling, 14x40 sliding doors, blown-in insulation, bathroom and kitchenette, plus a 22x12 loft, this space is ideal for comfortable living while construction is underway. It’s supported by a 500-gallon septic system and a powerful 58kW Samsung lithium battery storage and converter system. The off-grid setup is completed with a 33-panel 325W solar array, delivering a 10,000W output through dual Magnum hybrid inverters (110/220V), ensuring modern comfort in a wilderness setting.
Outside, the land is ready for sustainable living, with a 20x75 fenced garden, chicken coop, and year-round access maintained through plowing and vehicle readiness with chains or studs. Bordered on two sides by U.S. Forest Service land, the acreage offers limitless opportunities for recreation, exploration, and privacy.
Drink in the refreshing taste of mountain well water and experience the serenity that only nature can offer—all while staying connected with high-speed fiber optic internet, making remote work both practical and inspiring. With a bit of clearing, the surrounding mountains will open up to reveal a breathtaking panoramic view.
This is more than just land—it’s a lifestyle. Welcome to your Montana dream.
