Historic Gallatin River Retreat - Meticulously Remodeled with Modern Luxury || Step back in time without sacrificing modern comfort at this extraordinary Gallatin River retreat in the heart of Gallatin Gateway. Originally constructed in 1885 and completely reimagined from the studs out since 2020, this rare single-family residence masterfully blends authentic historic character with premium, contemporary upgrades on a 0.44-acre lot directly bordering the river. Nestled in the original Salesville Plat, across from iconic Stacey's and The Westerner, this un-zoned property offers unmatched charm, versatility, and investment potential--just 20 minutes from Bozeman and 45 minutes from Big Sky Resort. Inside, the home showcases its heritage with restored original cabin wood floors, walls, and ceilings, balanced beautifully by all-new electrical, plumbing, insulation, and high-efficiency architectural wood windows. Comfort and quality are built into every detail: in-floor radiant heat via a high-performance combi boiler, sound-dampened interior walls for privacy, and a striking see-through wood stove anchoring the living space. The custom kitchen combines warmth and function with handcrafted cabinetry, a walk-in pantry, gas range with hood, a bespoke island, and French doors opening to the backyard oasis. The primary suite features restored wood floors, floor-to-ceiling windows, and custom closets, while the spa-inspired bath boasts a fully tiled shower, restored clawfoot tub, artisan vanity, and stained-glass accent window. The property's outdoor amenities are equally compelling: a new roof, cedar siding, deck, and gutters enhance the home's longevity and style, while the fenced backyard offers a fire pit, flagstone patio, raised garden beds, and a powered new shed. Beyond the main residence, the property includes two versatile outbuildings: 1) A fully insulated, heated shop, ideal for woodworking, metalworking, or as a professional-grade workspace; 2) A 2nd detached structure, perfectly positioned to become a guest house, art studio, detached office, or creative retreat--offering boundless potential for customization. Whether you envision it as a full-time sanctuary, weekend escape, or distinctive investment, 407 Mill Street presents a rare opportunity to own a thoughtfully modernized piece of Gallatin Gateway history--complete with direct access to the timeless beauty of the Gallatin River.
