The priciest home in America is set to hit the market in Los Angeles later this year. Nile Niami, the developer known for such epic real-estate offerings as the $100 million "Opus" in Beverly Hills, has been working on "The One" in Bel Air for years. The $500 million, 105,000-square-foot "giga-mansion" will, indeed, likely be the only one of its kind, seeing as LA has tightened up building regulations since Niami started working on it, the Guardian reports. "One made for the one," reads the tagline of a promotional video for the house featuring a wealthy host with a red Ferrari hosting a party with many beautiful women. But Niami says most of his clients—typically single men who've made millions or billions in tech, finance, or oil—are just "normal dudes." Normal dudes who, he hopes, aspire to own a home with walls and ceilings made out of aquariums full of jellyfish.
The One also includes its own indoor/outdoor nightclub, four-lane bowling alley, and 40-seat movie theater; four pools, including the largest indoor pool in California; panoramic views of the city; and a moat that surrounds it all, per a CNBC look before the place was completed. Such opulent mansions have attracted criticism as LA experiences a homelessness crisis, but Niami, 50, wasn't interested in discussing inequality with the Guardian: "You're asking the wrong guy. I try to provide things that don't exist to buyers that can afford them." If The One sells for its intended price, it could be the most expensive not just in the US (where the current record is a $137 million Hamptons home), but in the world: A French chateau purchased by Saudi Arabia's crown prince went for a reported $300 million. But Niami's Opus hasn't yet sold, and he recently downgraded it, dropping the price to $77.5 million. (Read more luxury real estate stories.)
