Instead of replacing the old mainline station with a wholly new building on the Airport forecourt (Jan Dellaertplein), the latter was partly roofed over. The glass roof structure was primarily meant to flood the arrivals hall below with light and fresh air. But the resulting space was found to be suitable for a mall in the new shopping centre. Sited below the departures halls, which are still clearly recognizable as such, are forty shops, kiosks and eating establishments. Removing part of the ground floor of the two arrivals halls has generated a terminal where not just planes come and go but trains too. Only a limited height between these two functions needed bridging. The roof curves upwards to create a roofed footbridge which leads to the new parking facilities, hotels and office complexes. All told, Schiphol Plaza is an interchange worthy of the name.
