Real EstateDisney-inspired 70K-square-foot mansion — the largest single-family home in Utah — hits the auction blockBy Emily DavisPublishedJune 3, 2025, 12:59 p.m. ET

Utah’s largest home comes with 70,000 square feet of space and Disney-fied decor.

Left partially unfinished, the resort-like mansion is headed to auction on Friday with starting bids expected up to $8 million.

Located on a 154-acre ranch in Hyrum, Utah, the gargantuan home was the brain child of a wealthy tech founder, Cache Valley Daily reported. Its impressive size and theme park-like decor has

The listing, a little over an hour north of Salt Lake City, is held by Summit Sotheby’s International Realty’s Kerry Oman.

“This estate is truly unlike anything else in the western United States,” Oman told the outlet. “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.

The home, known as Lazy R Ranch, was constructed six years ago by Richard Spillman, the outlet reported. Spillman made his fortune in 2016 when his software company, Spillman Technologies

Inc., was acquired by Motorola.

With his giant Western ranch-style megamansion, Spillman aimed to host large family and company retreats.

The five-level main house, built in 2019, is currently listed for $19.5 million on Zillow. Its eight bedrooms offer the usual mansion trappings — vaulted ceilings, walk-in closets, wet bars

and ensuite bathrooms — but the themed rooms make the home quirky.

There’s a “Swiss Family Robinson”-inspired bunkroom, a replica of Disneyland’s Tiki Room, a “Cars”-themed raceway and a Frontierland-themed shooting range.

Spillman put the residence on the market before it was completed, including an in-construction pool barn rising 53 feet tall and spanning 27,080 square feet. The space is poised to host a

swimming pool, an exercise area and an event space, according to the listing. 

The barn is connected to the main house by a 2,266-square-foot concrete tunnel reminiscent of a secret base in “Star Wars.” 

The property also offers a guest house and a five-bay shop.

The megamansion initially listed at $35 million in December 2024, according to Realtor.com, and online commenters did not hold back their opinions. 

“This is more of a ski resort than it is a home,” one Reddit user wrote.

“Seems like an odd location for a BASS PRO SHOP,” another commented. 

Others were more generous with the home’s unique decor choices. 

“Can’t go to Disney?” a Redditor wrote. “Bring the tiki room to you.”
