MOST EXPENSIVE BUILDINGS IN THE WORLD

At a construction cost of US $ 5.50bn , Marina Bay Sans is the most expensive resort ever built . The construction consists of three connected 55 story towers and is situated in an area of 38 acres , with the building billed as the world ’ s most expensive standalone casino . Construction was completed in 2010 , one year later than planned due to escalating material costs and a shortage of workers , and was overseen by Ssangyong Engineering and Construction contractors , with design by Moshe Safdie . The architecture and design of the resort were all approved by feng shui consultants .
