Over a year after a La Jolla, California, mansion dubbed the Razor House hit the market, the modern dwelling built by AD100 designer Wallace E. Cunningham has found a buyer. Alicia Keys recently dropped $20.8 million on the 10,653-square-foot stunner, almost $10 million less than the original asking price.

The incredible multilevel abode—which is often compared to Tony Stark's luxurious home in the Iron Man movies—is perched on the edge of a cliff overlooking the Pacific Ocean. Nearly all of the walls of the residence are glass, providing sweeping views of the landscape from almost every room—and there's even a glass elevator. Inside are four bedrooms (including two master suites), a giant round living room with a fireplace, a fitness space, two steam rooms, a library, a den, a theater, and a kitchen outfitted with Gaggeneau, Miele, and Hoshizaki appliances. The floors are mostly travertine stone, with walnut flooring in the library, where there is also a custom-made Ralph Lauren pool table. In the family room, there's a custom-made shagreen liquor cabinet and bar.

The home gets its name from its sharp angles and its location near Razor Point.

Outside there are several lounge areas, including a rooftop entertaining spot featuring a kitchen. The infinity pool hovers just over the cliff, providing a one-of-a-kind swimming experience. There's also a cozy courtyard featuring a firepit, plus an additional 1,301-square-foot, two-bedroom guesthouse on the premises.

The structure is made of polished white concrete, steel, and glass.

The previous owner, Donald Burns, revealed that he bought the home for about $14.1 million in 2011, and finished constructing it. He told the Wall Street Journal that he was happy the new owner "appreciated the architecture," but didn't mention Keys by name.

Amazing views abound throughout the dwelling, even in the bathroom.

Keys, who has been married to rapper and music producer Swizz Beatz since 2010 (they share two children), also owns a home in Arizona and one in New Jersey, which was on the market in 2015, though it is unclear whether it ever sold.
