Now, finally complete, this astonishing property perched high on a 3.8-acre hilltop, with 360-degree views of the Pacific Ocean, downtown Los Angeles and the snow-capped San Gabriel Mountains, almost defies description. To put that 105,000 square feet of space into perspective, it’s twice the size of the White House, and overshadows the 68,500 square feet that’s Hearst Castle in San Simeon, California. Mar-a-Lago in Palm Beach? No comparison at just 62,500 square feet.
