While One World Trade Center in New York tops the list of the tallest buildings in the western hemisphere, it also holds another distinction it is probably not so proud of: the world’s most expensive skyscraper. Buildings Analyst Emporis recently released a list of the top ten costliest skyscrapers in history. The $3.9 billion One World Trade Center tops the list followed by the $1.9 billion Pallazo in Las Vegas and the $1.9 billion The Shard in London. In fifth place is the world’s tallest building, the Burj Khalifa. The $1 billion Bank of America building in New York is North America’s third representative on the list.
