The team led by Norman Foster, in collaboration with the young Mexican architect Fernando Romero and the Dutch N.A.C.O., will design the new international airport for Mexico City. Six other studios participated in the competition: those of Zaha Hadid, Richard Rogers, SOM, Gensler, Pascall + Watson, and Teodoro González de León. With a design that permits future extensions, the new airport will go up in the Lake Texcoco area on a site near the current infrastructure, and, at 470,000 square meters, it will become one of the world’s largest. Based on natural lighting principles, the complex and detailed project will mark a turning point in the design of airport buildings.
