A 12,981-square-foot seaside megamansion dubbed “The Sand Castle” in La Jolla, CA, that gives Versailles vibes overlooking the Pacific Ocean is this week’s most expensive home on Realtor.com®—edging out competition from a $38.9 million Florida property that hasn’t actually been built yet, despite its staggering price.
The nearly 1-acre oceanfront estate offering unobstructed Pacific Ocean views got its name for its “tone-on-tone palette” designed to mirror the sea.
Perched on a cliff overlooking La Jolla Bay, the 10-bedroom residence is said to be owned by billionaire Darwin Deason, a founder of Affiliated Computer Services that later sold to Xerox for more than $6 billion.
Therefore, “no expense was spared” when Deason built this palatial pad in 2015, reminiscent of a French Riviera manor with its solid gold gilded rooms and bespoke statues and chandeliers. The spread also has a guesthouse, a “magical” courtyard, and even a boat bar. And it’s home to one of the only on-property private beaches in California.
Other pricey properties this week include a mixed-use New York brownstone and a 1,940-acre ranch in Montana.
