Nicknamed the "billionaire building," the ultra-luxury One57 tower, located at 157 West 57th St. in New York City recorded the most expensive purchase price the state's history in 2012: more than $90 million. The buyer of the 10,923-square-foot (1,012-square-meter) penthouse, which occupies both the 89th and 90th floors of the Midtown highrise, remains shrouded in secrecy [source: Barrionuevo]. The New York Post leaked that it was Sheik Hamad bin Jassim bin Jabar al-Thani, the prime minister of Qatar, but One57 spokespeople denied the rumor [source: Brennan]. Whoever bought the penthouse is getting quite a bargain, since it was originally listed at $115 million.

Even though the One57 tower is still under construction, more than half of its 92 apartments are spoken for [source: Barrionuevo]. The building will also be the home of the new Park Hyatt flagship hotel, and residents will benefit from the luxury hotel's renowned service. The penthouse features 23-foot (7-meter) ceilings and glass curtain walls offering a panoramic view of Central Park below. Its sales price of roughly $8,000 per square foot was actually cheaper than the $13,000 per square foot Manhattan apartment bought by Russian billionaire Dmitry Rybolovlev, but that penthouse went for a paltry $88 million total [source: Brennan].

The next most expensive home belongs to a famously outspoken New Yorker with luxury properties around the world.
