Hong Kong's Bank of China building was designed by award-winning architect IM Pei and houses the Bank of China Headquarters. The huge financial institution was formerly based in a 'modest' 17-storey stone edifice elsewhere in Hong Kong, but moved to the 72-floor building in 1989. The tower courted controversy when it was constructed largely without consultation from Feng Shui masters, typically a routine step in the construction of tall buildings in China.
