Le quartier des Halles revu et amélioré.
The neighbourhood called "Les Halles" in center of Paris must be transformed. That is the scale model.
"Tree is leaf and leaf is tree. House is city and city is house. A tree is a tree but it is also a huge leaf. A leaf is a leaf but it is also a tiny tree. A city is not a city unless it is also a huge house. A house is a house only if it is also a tiny city".
