Liantang Boundary Control Point Passenger Terminal Building

Water Gate (一水相连)
Concept Design

Client: Government of Hong Kong SAR
Size: 17 Hectares
Location: Heung Yuen Wai, N.T., Hong Kong

One building; three atriums - Atriums at both ends’ passenger loading area create focal points for drop off and pick up. Atriums help orientating the immigration building, by providing visual connections to all floors.

Water layer on roof cools the neighborhood - The thin layer of water on roof performs as a thermal buffer for both the occupied space below and its surroundings. The Water Park on roof provides a “stop over” space for the passengers (restricted area for passengers crossing immigration). It is also home for many species of birds and insects in the area. 

Roof form memorizes ancient city gates - The arch-form soffit resembles the sequential experience and spatial hierarchy of passing through under gate arches as in traditional Chinese architecture. Roof space frame structure borrows the idea from roof bracket system in ancient China.

Wind towers draw in breeze - Wind towers on roof divert wind into building. Water fall in central atrium help regulate temperature in immigration halls.

The roof purifies river underneath, at the same time using the river water to chill the ceiling - River pumped through pipe structures within roof zone for purification before discharging the water back to the river. The water filled roof pipes perform as chilling ceiling system to cool down the occupied floor below.

High flexibility in planning and structure - The simple and regular floor plates with modular office blocks provide highest flexibility for future re-planning and expansion. Roof is assembled by repetitive scaffolding pipe structure. This allows flexibility in construction phases and future modification.
