Feng Shui
The early British settlers in Hong Kong had an interest in Feng Shui; thus, most of the earliest buildings in Hong Kong, and many buildings constructed thereafter, were built with the philosophies of Feng Shui in mind. The Chinese believe that those who have a direct view of a body of water—whether it is a river, a sea, or an ocean—are more likely to prosper than those who do not (water is strongly associated with wealth in Feng Shui). The HSBC building has a wide open area (the Statue Square) in front of it, with no other buildings blocking its view of Victoria Harbour; thus, it is considered to have "good feng shui."
Even though the Hong Kong Government is proposing extending the existing coastline further out into the harbour in its latest land reclamation project, it will still set aside space so that no new developments will block the HSBC Building's view of the harbour. (It has been said that the HSBC is guaranteed its view of the harbour by the government.)
