The Hong Kong International Airport Preschool is a new facility that caters to the day care needs of airport employees. Besides serving the employees’ children, the preschool also hopes to inspire other corporates to offer similar service. The preschool is adjacent to Terminal 2 and enjoys a view to the Lantau mountains through the 7m high curtain wall. The design takes full advantage of the height and daylight and provides as much room as possible to the children. All the utility spaces line the back wall and they are given the form of a series of pitch roofs to decrease the massiveness. The roof pitches transform into a wooden diagrid which wraps the back wall and the ceiling, which helps to conceal the building systems, and accentuate the gradient of soft colours in the space. Every effort is made to minimize voc in this space, from certified furniture suppliers, to flushing the space with fresh air per leed standards.
