Tech magnate Darwin Deason’s opulent “Sand Castle” mansion in La Jolla, inspired by Versailles, is now on the market for $87.5 million after an initial listing at $108 million. This extravagant 13,000-square-foot estate boasts imported marble, gold accents, and even sand from Augusta National. Despite the price reduction, it remains San Diego’s most expensive residential listing, aiming to break the $100 million barrier.
