This apartment in Tribeca, New York, is running for a whopping $45 million dollars. Designed by JCDA and Rogers Marvel Architects, this penthouse suite sits atop a renovated building after it was burned down. The 7,500 sq. ft. interior is cased inside a completely glass exterior. It also comes with a 4,500 sq. ft. outside terrace. Using mainly metal, wood, and marble, this apartment is very contemporary. It originally went for $30 million USD, but it came back on the market two years later at $45 million USD.
