Welcome to a once-in-a-lifetime architectural masterpiece at the mouth of Big Cottonwood Canyon. Designed by acclaimed architect Guy Dreier, this 9907 sq ft estate is a stunning fusion of modern design and the raw beauty of nature. Set on a dramatic mountainside lot just across the canyon from Post Malones residence, this home is as visually striking as it is unforgettable. With a sweeping roofline that evokes the elegance of vast sails, the architecture soars-inside and out. Floor-to-ceiling glass walls fully retract to reveal an infinity pool, a cascading waterfall that flows beneath a glass-floor hallway, and a cliffside hot tub just off the primary suite. Every element is designed to blur the line between indoors and out. The home has been completely reimagined with the finest materials. Nearly 1,500,000 in recent upgrades have been invested throughout the home, elevating both form and function with the finest materials and attention to detail. The chefs kitchen is a showpiece of both function and style. A full guest suite downstairs offers comfort and privacy, and the unfinished second basement is the perfect setting for a future home theater. The south wing is structurally engineered to support a second story, unlocking unobstructed 180-degree views of the entire Salt Lake Valley. The expansive lot stretches up the mountain with space to add a second guest house or retreat. This is more than a home-its a landmark of inspired living.
