19 White Grass is a sun-filled, ski in/ski out mountain residence completed in January 2023, offering a rare blend of modern luxury, energy efficiency, and thoughtful design in a cul-de-sac location. This home features one of the very few Big Sky properties with an automated oxygenated bedroom, allowing rapid acclimation to high altitude. Positioned to capture sweeping views of Lone Peak, Andesite and the Gallatin Range, this five-bedroom, five-and-a-half-bath home spans 5,052 square feet and is designed for effortless year-round living in Big Sky. Expansive windows, covered decks, and multiple outdoor gathering spaces invite you to take in the scenery in every season. Built for comfort and durability, the home features geothermal heating and cooling, radiant floor heat, humidification, central air conditioning, and a cold roof - setting this mountain property apart from other luxury homes. Fire-conscious construction includes a fiber cement exterior and a full fire-suppression system, offering both efficiency and peace of mind. Every detail has been carefully considered to create a home that performs as beautifully as it lives. Interior spaces are thoughtfully appointed, beginning with a dedicated ski room for seamless mountain access. Exceptional storage throughout the home ensures space for all seasons - from mountain gear and recreational equipment to owner storage and everyday essentials - making organization effortless. The main living area showcases hardwood flooring, quartzite and marble finishes, Sonos audio, and multiple propane fireplaces - including a striking double-sided fireplace in the primary suite. The suite also offers direct access to a private hot tub, while invisible screens on exterior doors allow fresh mountain air to flow freely. A walk-in pantry and potential for a wine room elevate the entertaining experience, and abundant natural light enhances the home's warmth and inviting atmosphere. Flexible upper- and lower-level living spaces provide exceptional versatility. The lower level can serve as a private retreat and can be locked off for rental potential, featuring 3 bedrooms, 3 bathrooms, a living area with kitchen, a private hot tub and a fire pit. With ski access via the Cascade Lift, exceptional build quality, abundant storage, and a new-construction feel, 19 White Grass presents a rare opportunity to own a high-performance luxury mountain home in one of Big Sky's most sought-after settings.
