In 2050, 80% of the population will live in major urban centres. These cities are the theater of a cultural intermingling putting in perspective the question of living together and the major challenge of making society in a city. A place representative of these realities is Massy. As the southern capital of the future Grand-Paris, Massy was today perceived as a two-speed city, creating divisions between a desire to modernise the construction of new districts and a real difficulty in transforming the reality of large complexes. It is a major topic for a city facing a social, economic and cultural divide to create social and spatial responses.
