Winner of the prestigious People’s Choice Award for the 2025 Salt Lake Parade of Homes (along with the Best Kitchen, Best Primary Suite, and Best Interior Design). This 15,000 square foot architectural masterpiece combines modern sophistication, comfort, and creativity as the largest certified single-family Passive House in the world. Knowing the home is a certified Passive House means it meets the world's highest standards for energy efficiency, indoor air quality, and long-term sustainability. Set on a beautifully landscaped one-acre estate, it features eight bedrooms, ten bathrooms, and three kitchens, including a private two-bedroom guest apartment. Designed for entertaining large groups, indoor/outdoor spaces abound with comfortable seating for well over 50 people. Every detail reflects thoughtful design and craftsmanship, from the gourmet kitchen with walnut cabinetry and dual ten-foot islands to the resort-style pool, racquetball court, and inviting Hobbit room that brings a sense of wonder to the home. The twenty-seat theater is an entertainment masterpiece with a twenty-foot screen, a bright commercial-grade projector, and a fully immersive Dolby Atmos sound system powered by nineteen speakers and four subwoofers, creating an experience that surpasses most professional cinemas. Powered by geothermal and solar energy with a HERS rating of 30, triple pane Alpen windows, and continuous filtered fresh air, the home provides quiet, draft-free comfort in every season, creating a living environment unlike any other in Utah. Located near the tech hubs of Lehi and Draper, it is a rare combination of art, technology, and sustainable luxury, offering an unmatched experience along the Wasatch Front.
