Villa “Versailles” on a cliff in California costs $108 million after 15 years of construction

Perched on the cliffs of La Jolla Bay, Darwin Deason's mansion is not your typical California beach vacation spot. Nicknamed “The Sandcastle” by locals, the property is a Versailles-esque architectural marvel set high above the Pacific.

According to agents Brett Dickinson and Ross Clark of Compass, it's now poised to break records as it hits the market for a staggering $108 million.

If the lavish property sells for its asking price, it would shatter San Diego County's current real estate record set earlier this year when billionaire Egon Durban splashed out $44 million on an oceanfront property in Del Mar.

Deason's Sandcastle offers nearly 13,000 square feet of opulence with intricate stone columns, expansive balconies and its own private elevated beach.

Inside, it's an ode to old-world Europe, with extravagant mosaics, marble floors, and rooms gleaming with solid gold accents. The guest house is modeled on Le Petit Trianon in Versailles. Deason, who founded Affiliated Computer Services and sold it to Xerox for more than $6 billion in 2009, purchased the Sandcastle and an adjacent property for $26 million that same year.

Although he is based in Dallas, Texas, where he is a prominent Republican donor, he uses the La Jolla property as a vacation spot.

Originally built in 2005 by San Diego developer Doug Manchester, the mansion offered exactly what Deason was looking for: stunning views in three directions.

But that wasn't enough for the billionaire. He stripped the house down to its foundations, rebuilt it, and added the Versailles-inspired guesthouse.

His vision? A fusion of French elegance and the legendary Hotel du Cap-Eden-Roc in Antibes, a place he has long admired. To adapt the interiors to his grand vision, he hired top designer Timothy Corrigan, whose clients include Hollywood elite and royalty.

The property spans 0.8 acres and includes 10 bedrooms.

The large living room in the main house features ornate coffered ceilings and a wall of bay-view arched windows leading to a huge wraparound terrace. A dining room seats 16 beneath a crystal chandelier with gold leaf trim and matching antique cabinetry.

The guesthouse has a special feature: a nautical-themed bar modeled after the one on Deason's yacht, complete with sea-inspired paintings and two 18th-century mermaid statues.

Outside, the mansion's grounds include a pool, fitness center, and even a wood-paneled office near the master suite.

Every piece of furniture was custom-made for the property, from the carpet to the curtains. And Deason didn't just limit himself to the house.

Not a fan of California's gritty beach sand, he had about $40,000 worth of sand imported from the same source used by Augusta National Golf Club in Georgia.

“Anyone who watches the golf tournament knows it’s a spectacular shade of white,” he said Wall Street Journalwho first reported the listing.

There are two cabanas and a beachfront boathouse with a kitchen. The slate roof tiles for the boathouse? Deason imported them from a Chinese quarry after selecting the perfect color and pattern to secure as much material as could be mined.

“I bought as much material as could be mined,” he said.

As if that wasn't enough, there are two natural caves on the ground floor of the property.

In total, Deason estimates he put about $60 million into building the property, not including land costs. Despite all the effort and money, Deason says it's time to let go of the Sandcastle, admitting he doesn't use the property as much as his other homes, which include a mansion in Dallas, a lakeside retreat in the Close to Cedar Creek Lake and a vacation rental home in Cabo San Lucas.

“In the history of La Jolla, due to current oceanfront construction standards set by the State of California, no other waterfront property like The Sand Castle has ever been and will never be built on the waterfront,” the agents said in a statement to The Post.

“The opportunity to combine the two parcels at this location is so rare, and this fact coupled with the seller's vision of bringing the French Riviera to the La Jolla coast without cutting any costs,” they added .
