An Adaptive Re-use Architectural Design to provide a new life to an existing architecture by reintroducing new functions and new elements to transform a "Re-birth" to the architecture in a Hyper-Density City. In a Hyper Density City like Hong Kong, there are no more lands to be build. Therefore the strategy of Re-Cycling the existing abandoned architecture by Re-introducing new functions and elements to Re-Create the Adaptive Re-Use is a MUST. Adaptive Re-Use in Architecture is a vague, premature topic in Hyper-Density City like Hong Kong, but is a kind of Sustainability and Adaptability in City Planning, thus is a hot topic of future vision of Architectural Development in populated Asian country.
