Post-Kyoto Paris and the future prospects of the Parisian agglomeration were the subject of an important consultation that the president of the Republic Nicolas Sarkozy commissioned a year ago through the Ministry of Culture and Communication with support from the Municipality, the Île-de-France region and the Île-de-France association of mayors. Ten teams of international teams of architects and town planners were called upon for a particularly intense job of reflecting on the current state of the city territory and developing visions on a grand scale. Proposals from the multi-disciplinary teams lead by Richard Rogers, Yves Lion, Djamel Klouche, Christian de Portzamparc, Antoine Grumbach, Jean Nouvel, Bernardo Secchi and Paola Viganò, Finn Geipel and Giulia Andi, Roland Castro, Winy Maas have the spirit of research (see all the projects on: https://www.legrandparis.culture.gouv.fr ). The immense volume of ideas matured in this first phase has been distilled into ten sharp, white pavilions, conceived and planned by Jean-Christophe Quinton in a gallery at the Palais de Chaillot, the inside of which have been designed by the individual practices. Aside from this moment of public communication, the proposals are soon to be brought together in a single workshop for further development: a new challenge that while set in the context of Sarkozy’s incredible move, at the same time offers a positive provocation for the world of architecture, bewildered and confused by economic crisis.
