Conceived as a gateway to the city, the Terminal building is identified on the skyline - raised up from the road level giving the appearance of sitting on its own plateau – with a profile silhouetted against the sky. Its undulating form is, in part, created by the roof of the piers along the X ‘pulled down’ on the facade protecting the building and its habitats from the sun. At night the building’s illuminated interior creates a transparent structure which is visible from the highway over 1,500 metres away.
On approaching the Terminal Building the roadway system and landscaping work together to create a sequence of events culminating in a monumental civic space inside the terminal. Internally the scale of the Departure Hall - a 50-metre high space rendered largely column-free through the use of long span leaning arches - endows the building with an open, outdoor quality, with the supporting arches visually separated from the roof to enhance the lightweight feel. The civic nature of the central space, the heart of the X-shaped complex, is complemented by retail and food outlets, a programme of public art including a gallery space, and a secluded garden.
Guided by the project’s environmental objectives, the building also includes a number of measures including the reduction in the use of potable water by using dry climate landscaping and the efficient use of natural daylighting supplemented with low energy lighting.
