Hong Kong, a man-made city from top to bottom, with its dense concrete forest and large area of habitable land created by decades of reclamation; all this only a few meters above sea level on average. Thus, the city is threatened by substantial climate change which caused sea level rise and more frequent extreme weather, heavy rainstorms and especially super typhoons that will bring severe storm-surge and lead to flooding in all low-lying districts including Kowloon, Hong Kong, and coastal districts in new territories. Flooding will affect the functionality of the city’s transportation system and consequently the mobility of people, especially in Hong Kong where the population relies a lot on public transportation for the operation of the whole city. Not having functional transportation working would paralyse the city and cause unrecoverable loss of lives and money.
This project, based on this upcoming crisis, proposes an idea for adapting to the forces of climate change by embracing the ecological edge, with platforms of nearshore habitation as prototype, to coexist alongside a natural waterfront. It focuses on exploring an effective way to confront the rising sea level and the potential flooding problem while allowing a co-habitation between land and sea in order to generate more habitable surface for the future development of city. Tolo Harbour is chosen as the testing site which has revealed its sensitivity to the change of weather due to its alcove shape and the mountainous area surrounding it, causing the most significant tidal variation within Hong Kong’s water zones.
The design project mainly consists of 3 parts:
(1)Flooding control structure that connects the shores on both sides of the harbour and functions as a flooding regulator and circulation connector, it creates a typhoon-sheltered zone for ship vessels and ensures the safety of the main downtown area by blocking off the tide and controlling water level.
(2)Research and Education Center for the research of climate change on urban development and marine ecology.
(3)Floating platform extends from the shore with experimental set-up on the platform. It acts as an experimental model to demonstrate the feasibility of small-scale nearshore development that guarantees a secure habitable space for human activities above the water surface.
