The document outlines The MET Workshop, which examines three former airports - Mariscal Sucre in Quito, Elliniko in Athens, and Tempelhof in Berlin - as potential metropolitan commons. It discusses dilemmas around flows and enclosures, geopolitical imbalances, scale and history, private vs public spaces, and top-down vs participatory planning. The workshop brings together urbanists, citizens, students, and activists from the three cities to explore governance models and envision the futures of these spaces through peer-to-peer collaboration across local and global networks.
