Perched to capture spectacular views, this 10,500-square-foot architectural masterpiece redefines mountain luxury with an offering price of $19.5M, fully furnished and move-in ready. This grass roofed residence flexes between 5 and 6 bedrooms - including a dedicated gym - with thoughtful design ensuring every livable space is bathed in natural light. A rotating motorcourt leads to a striking 3-car garage with a rare side-sliding door that moves right to left setting the tone for the innovation found throughout. The outdoor living here might be the best in Promontory with a design that includes turf, an infinity edge pool, attached hot tub, and linear fireplace spread over close to 2000 square ft of gathering space. The primary suite features an expansive closet built for the most discerning collector, while the private office frames a living tree that grows through a custom opening in the flat grass roof above - a seamless blend of architecture and nature. At least five La Cantina doors dissolve the line between indoors and out, opening to multiple outdoor entertaining areas. Multiple fireplaces and whole-home radiant heat and water filtration provide warmth and ambiance through every season. Golf membership availability adds the final layer of privileged access to this one-of-a-kind estate. A portion of the lower level is your personal 900-square-foot wellness retreat awaits, complete with a plunge pool, sauna, steam room, and a Himalayan sea salt wall. This multigenerational home is why you keep coming back and why your family will want to return over and over.
