3) Bank of China Tower, Hong Kong
It makes sense for a bank to be one of the most expensive buildings in the world. This 72-floor tower bank cost US$2 Billion to build and was designed by I. M. Pei & Partners. It had a minor role in the Hollywood films Battleship and Transformers: Age of Extinction. It's considered an aggressive building when it comes to Feng Shui, as the edges of the triangles at the front point to its competitors. In Feng Shui triangles can be seen in a negative way and can be used as a “direct attack”.
4) Antilia, Mumbai
Business man Mukesh Ambani is worth an estimated $22.3 billion, so dropping $1 Billion on his home is probably like, no biggie. His family home is actually a 27-storey skyscraper in Mumbai and contains three helipads, 168 parking spaces, 9 elevators, terraced gardens, a 2-storey recreation centre and a temple. Marble and crystal emblems of the sun and the lotus recur throughout the 400,000 square-foot property, which is home to Ambani, his wife and three sons. And all their staff, of course.

6) One World Trade Centre
One of the most expensive skyscrapers of all time and the tallest building in the Western Hemisphere, the One World Trade Centre, or Freedom Tower, was built in memory of those who lost their lives in the September 11th Terrorist attack in 2001. Skidmore, Owings & Merrill’s 541-metre-high tower on the Ground Zero site cost around $3.9 billion USD to build.

The sacred mosque in the city of Mecca is not only Islam's holiest place and largest mosque, it's also the most expensive building in the world.

Muslims around the world also face the Kaaba during their prayers, this is called facing the Qiblah. With all that in mind it's clear to see why it's such an important building. The mosque covers an area of 88.2 acres and the square foot is sometimes referred to as the holy metre as it costs over 11,452.84 USD. Columns are painted in gold, mosaics adorn countless walls and the in-house prayer room can house up to 2 million worshipers.
