1589 Cougar Drive Private Hyalite Foothills Retreat | 3.27 Acres | 360-Degree Mountain Views. Set quietly on 3.27 gated acres, this property pairs privacy, usable land and mountain views in every direction, approx. 20 minutes to Bozeman and 45 to Big Sky. Originally built in 1978, the home has undergone a seven-figure transformation: new oak floors, custom cabinetry, marble baths, new heating/AC, new windows/sliders in major areas, extensive electrical upgrades, renewed outbuilding siding and a property-wide sprinkler replacement. Light-filled living centers on vaulted timber ceilings and a black stone wood-burning fireplace, with sliding doors to two patios. Chef's kitchen: quartz waterfall island, mosaic backsplash, 48-inch Wolf double-oven range/griddle, Wolf convection steam oven and microwave, Viking fridge/freezer, Cove dishwasher and Zephyr hood. Dual Galley workstations, a wine/coffee area with hot/cold/sparkling water, glass rinser, beverage fridge and dual-zone wine cooler, plus a walk-in pantry with extra fridge space. Three ensuite bedrooms include two primary suites, one on each level. Main-level primary: walk-in closet, outdoor access, soaking tub and RH vanity. Two bright main-level offices, both prepped for radiant floor heat, support a true work-from-home lifestyle. Dedicated laundry; mechanical room with water treatment. Upstairs primary: Bridger views, dressing area, marble bath, RH double vanity and glass shower. The third ensuite has a shower bench and extra-wide sink. An additional living area with a galley kitchenette and wine/fridge unit, originally a bedroom, is ideal for guests, a media lounge or future conversion. Outdoor living is integrated, not added on: a covered, glass-screened garden patio with ceiling heaters, open firepit patio, hot tub, panoramic Bridger-view sauna, gazebo, enclosed garden and pond with waterfall. A gardener's dream custom greenhouse adds planting benches, water and lighting.
