Bel Air, California
The paint is still drying, and the final landscaping is going in. But the world’s first giga-mansion – The ONE on a Bel-Air hilltop – is finally nearing completion. What hasn’t changed is that eye-watering price tag, a staggering $500,000,000 as in half a billion dollars. What that impressive sum will buy you is a 100,000-square-feet, 20-bedroom compound perched high above Bel Air on four acres, with spectacular 360-degree uninterrupted views. It’s the creation of movie producer turned prolific real estate developer Nile Niami and architect Paul McClean, who have taken seven years to construct this ultimate spec-home. Among its multitude of jaw-dropping features; a 5,500-square-feet master suite, 30 bathrooms, a 30-car auto ‘gallery’, five swimming pools, a 36-seat movie theater, six-lane bowling alley, and naturally, a nightclub.
