One of the most singularly unique private residences ever brought to market in the United States—a 70,000-square-foot estate in Hyrum, Cache Valley, Northern Utah—is headed to auction.  Listed for US$34.5 million in cooperation with Kerry Oman of Summit Sotheby’s International Realty, the ranch-style estate stands as the largest private residence in Utah, designed to offer a retreat-like experience with capabilities for entertaining on a monumental scale. Bidding is set to open on 15 May via our firm’s online marketplace, culminating on 29 May at Sotheby’s London as a part of the ‘Exceptional Global Properties’ sale.

Situated near Blacksmith Fork Canyon and Hyrum Reservoir, with Logan just 15 minutes away and Salt Lake City a 75-minute drive, this expansive estate offers both seclusion and accessibility. At its heart is a five-level, 45-foot-tall ranch-style main residence connected by a tunnel to the pool barn, thus making it one structure, and Utah’s largest private home. The home boasts a 40,807 sq. ft. main residence, a 27,080 sq. ft. indoor pool barn, and a 2,266 sq. ft. tunnel. 

Designed for gathering, entertaining, and making unforgettable memories, the home includes eight ensuite bedrooms, including an elegant primary suite and seven additional rooms, each with vaulted ceilings, walk-in closets, wet bars, and private baths.

Awe-inspiring themed spaces infuse whimsy and creativity into the luxurious design, from Swiss Family Robinson-inspired bunkrooms to a replica of Disneyland’s Tiki Hut and a shooting gallery reminiscent of Frontierland. The expansive open-plan main level includes a kitchen and dining room with a custom-built 42-seat table, along with a great room designed for multi-generational entertaining. The lower level includes a massive 62-seat theater room and an underground raceway that loops beneath the entire building footprint. A 2,266-square-foot tunnel, reminiscent of a Star Wars episode, connects the main home to a separate 27,080-square-foot pool barn—a structure standing 53 feet tall and poised to house a future indoor swimming pool, gym, and large event space, in addition to a 16-car garage.

Additional structures on the property include a guest house, a five-bay shop, well house, and a nearly complete large pond. The main home’s garage—affectionately known as the “Bat Cave”—accommodates four more vehicles. The estate’s outdoor offerings are equally impressive, with horse-friendly acreage, scenic views, and a gated entry off Highway 165. These features combine to create an unmatched level of privacy, luxury, and versatility.

“This estate is truly unlike anything else in the western United States,” said Oman. “It offers an unmatched combination of space, luxury, and versatility—creating a perfect environment to live, entertain, and make memories that will last a lifetime. Whether you’re hosting family gatherings, special events, or simply enjoying the breathtaking views and peaceful surroundings, the estate will deliver an incredible living experience."
