A $55 million Arizona mansion with an underground shooting range, AI-powered security and a driveway stretching the length of two football fields is gunning for the state’s most expensive home sale ever.

The sprawling Paradise Valley estate takes security to another level, with fortress-like walls designed to keep intruders out, facial-recognition surveillance that can distinguish dogs from coyotes — and a subterranean bunker stocked with enough food to last half a decade, according to its listing agent.

The twist? The current owners aren’t particularly interested in guns. The previous owner installed the underground shooting range, but the current owners have repurposed the space into a doomsday-ready retreat.

“The current owners actually have five years of food in there,” listing agent Katrina Barrett told The Post.

The home’s previous owner installed the underground shooting range out of a love for firearms, Barrett explained, but the current owners had different plans when they purchased the property for $33.5 million in 2025.

“They just wanted a use for downstairs since they weren’t big gun people,” she said.

The underground space, originally designed with concrete walls to provide a safe shooting environment, also includes bathrooms and a generator.

“If anything bad happened, it is nice to have that space,” Barrett said.

The unusual setup reflects a growing fascination among the ultrawealthy with doomsday bunkers and fortified safe rooms, with celebrities including Mark Zuckerberg reportedly investing in elaborate underground shelters.

But the bunker is only one layer of security at the secluded Arizona compound.

The property sits at the end of a private driveway roughly the length of two football fields, tucked between Casablanca and Wilkinson roads — two of Arizona’s most coveted addresses, according to Barrett.

“It’s kind of this hidden fortress in between two roads,” she said.

Double rows of ficus trees provide additional privacy, while the perimeter walls are equipped with coyote rollers, devices designed to prevent animals from climbing over and which Barrett said also help deter intruders.

Then there’s the AI-powered surveillance system, which Barrett said can identify faces, distinguish between animals and keep a log of activity on the property.

“If someone does get in, the AI security can identify faces, it can tell you if something is a dog or a coyote,” Barrett said. “It’s unbelievable.”

The elaborate precautions are particularly striking given the neighborhood’s reputation for safety.

“Paradise Valley has almost no crime at this point, so it’s not like you need to escape,” Barrett said.

She also pointed to the town’s drone-assisted emergency response program, which she said can send drones to a home within a minute of a 911 call.

Still, security isn’t the only thing the current owners have splurged on.

After purchasing the estate, they spent approximately $15 million transforming what Barrett described as a transitional-style home into a European-inspired retreat.

A staggering $7 million went toward landscaping alone, according to Barrett, including the installation of 30 ancient olive trees.

The owners also refurbished the furniture and incorporated design elements inspired by their travels throughout Europe.

“They took influences from their travels and recreated a lot of these really cool moments from Europe,” Barrett said. “It’s truly a work of art.”

The 23,417-square-foot estate boasts six bedrooms and a host of resort-style amenities, including a hidden speakeasy, golf simulator, pickleball courts and a wellness area with saunas and a cold plunge.

A separate guest residence makes the property suitable for multigenerational families or buyers looking for a private retreat to entertain business associates.

And despite the property’s extraordinary size, Barrett insists the home doesn’t feel overwhelming.

“The rooms are very big, but they’re not in excess,” she said. “It’s just an amazing scaled home.”

The property joins a growing collection of extravagant homes where unconventional amenities are becoming major selling points.

In New Jersey, an $8.95 million mansion with a 75-foot indoor shooting range hit the market last year, while a Cold War-era underground mansion in Las Vegas offered a swimming pool, theater and artificial skies designed to simulate life above ground.

At $55 million, the Arizona estate’s asking price is nearly $15 million above the state’s reported residential sales record of $40.2 million.

Barrett believes the combination of location, privacy, design and extensive upgrades justifies the premium.

“There isn’t a home that has traded like this,” she said. “If any home in Arizona ever deserved it, this is it.”

The listing has already generated early interest, with three showings scheduled within its first 24 hours on the market, according to Barrett.

She also pointed to the changing demographics of Arizona’s luxury market, where she said out-of-state buyers and cash transactions have become increasingly prominent.

“Most of the sales have been out of [state] and have been cash,” Barrett said. “So it’s just really changing the landscape of the state.”
