La Défense is the fourth most attractive business district in the world after the City of London, Midtown in New York, and Marunouchi in Tokyo. Its location, close to Paris and well served by public transport, and its innovative real estate offer have reinforced its ability to attract talent. While the other countries are struggling to find space for new buildings, La Défense continues to expand with the Trinity, Alto and Saint-Gobain towers. The greening of public spaces, water management, and the introduction of “soft energy” transport in recent years are beginning to bear fruit.
