The Story

Set on 6.33 private acres in the coveted Big Sky Mountain area, just two miles from Big Sky Resort and world-class skiing, 172 Ciel Drive is an exceptional alpine retreat offering rare privacy, refined custom craftsmanship, and stunning unobstructed views — all with no HOA and zoning in place for a future guest home. Surrounded by mature forest and mountain scenery, this exclusive property captures the essence of Montana living in one of the region's most sought-after settings.

Built in 2018, the residence spans 3,868 square feet and features a two-car garage, five bedrooms, three full bathrooms, one powder room and two fireplaces. Designed to balance timeless mountain architecture with modern luxury, the main level showcases an open-concept great room anchored by a dramatic stone fireplace and exposed beam ceilings — ideal for gathering and entertaining. The chef's kitchen features an expansive island with seating, custom cabinetry, professional-grade appliances, generous prep space, and hand-placed stone accents, with abundant natural light and spectacular mountain views.

The main-level primary suite offers a private sanctuary complete with its own fireplace, custom built-ins, and a spa-inspired bath featuring dual vanities, custom stonework, a walk-in steam shower, and a soaking tub positioned beneath picture windows. The walk-out lower level provides exceptional flexibility with a spacious family and recreation lounge, an additional fireplace, a custom wet bar with wine storage, built-in shelving, and guest accommodations well-suited for extended stays. A thoughtfully designed mudroom adds everyday functionality with ample storage and a dedicated dog wash station.

Outdoor living is equally inviting, with covered deck and patio spaces for year-round enjoyment, along with a fire pit area surrounded by Adirondack seating — perfect for evenings beneath the Big Sky stars. A defining feature of the property is its rare future expansion opportunity: approvals are already in place through the Gallatin City–County Health Department and Montana DEQ for a future guest house, served by a separately constructed access road.
