Hong Kong-Zhuhai-Macao Bridge Boundary Crossing Facilities
Under The Same Roof (同一屋簷下)
Client: Government of Hong Kong SAR
Size: 130 Hectares
Location: Lantau Island, Hong Kong
Sense of place - Mainland-Hong Kong cross border terminals have always been a place of hustle and bustle where travelers rush through immigration around the clock. Despite the high-volume traffic, these facilities are infrastructures that lack identity, communal associations, and public affection. Our proposal avoids creating yet another transit dessert by adding a layer of charm to it - a winter garden.
China, Macau and Hong Kong as one big family - With the return of Macau and Hong Kong to China, people from these three places are pulled closer together. Our architectural design is a symbolic and literal response to the idea of living "under the same roof".
A floating winter garden insulates the site - its double layer of space frame reduces energy consumption - Similar to the CLK airport, this site is highly exposed and over heated. A double layered roof across the site will immediately help cool the land. The winter garden will improve air quality and further regulate the climate through using the soil as a thermal mass. Algae tubes mounted on roof panels will generate oxygen under sunlight.
Vaults allow long span structures - efficient circulation for passengers and clear sight lines for staff - Immigration halls require the most efficient circulation and the most disciplined security controls. Our scheme intentionally maintains the efficient planning layout as set in the brief. Supporting the roof with two vaulted structures will reduce the number and size of columns required.
