Stillwater Retreat | Waterfront + Private Dock | House in Island Park

Set along the quiet shores of Bill’s Island, this luxury lakefront estate is designed for effortless gatherings and unhurried escape. Sleeping up to 18 across five private bedroom suites—each with a spa-style bath—the home blends refined mountain design with modern comfort. Vaulted cedar ceilings, a stone fireplace, and floor-to-ceiling windows frame expansive lake views, while a wraparound deck and private dock invite slow mornings and glowing sunsets. Just 30 miles from West Yellowstone.
Newly built and thoughtfully designed from the ground up, this lakefront estate on Bill’s Island represents the very best of modern mountain luxury. Every detail—from the architecture to the furnishings—has been professionally curated to create a home that feels both elevated and effortless. Set directly on the water with a private dock, this is a rare opportunity to experience brand-new construction in one of Island Park’s most serene and sought-after settings.
Designed for both gathering and retreat, the home sleeps up to twelve guests across five expansive bedroom suites, each with its own spa-inspired bathroom. Clean lines, natural materials, and a warm, cohesive palette define the interiors, blending refined mountain character with contemporary comfort.
The great room is the heart of the home, where vaulted cedar ceilings soar above wide-plank floors and a statement stone fireplace. Floor-to-ceiling windows frame uninterrupted lake views, allowing natural light to pour in from dawn through sunset. Every sightline, texture, and furnishing has been intentionally chosen to complement the surrounding landscape while offering a sense of calm and luxury.
The chef’s kitchen—fully equipped with stainless steel appliances, generous prep space, and an oversized island—is designed for both entertaining and everyday ease. Whether it’s slow mornings with coffee, celebratory dinners, or shared meals after a day outdoors, the space flows naturally and invites connection.
Step outside to experience true waterfront living. A wraparound deck extends the living space outdoors, furnished for lingering mornings and golden-hour evenings. Just below, the private dock offers direct access to the lake—perfect for fishing, kayaking, swimming, or simply enjoying the stillness of the water. Bald eagles often pass overhead, reinforcing the feeling that this home is immersed in nature without sacrificing comfort or design.
Each bedroom suite serves as a private retreat. One suite features a California king paired with twin XL bunks, ideal for families. Another offers multiple twin XL bunks, perfectly suited for group stays. The remaining suites each feature king beds dressed in crisp, hotel-quality linens, with tranquil views of water or forest. En-suite baths are finished with stone counters—spa-level comforts throughout.

Despite its peaceful setting, the home remains just 30 miles from West Yellowstone and the entrance to Yellowstone National Park, offering effortless access to world-class exploration while returning each evening to privacy and calm.
