Architects, planners, and citizens are constantly subjected to city zoning codes and regulations. What if zoning codes where created to promote 24/7 public life, partying, diversity, density, and free “L” rides? This urban research project took the death of public life in the loop, after the workday exodus, and explored a solution through the implementation of new zoning ordinances. The ordinances, devised as a group, began to promote and mandate the construction of activities on all rooftops within the Chicago loop. What resulted was a diversity of activities that simultaneously redefined building density, population density, and the public atmosphere. The following image is the resulting looptops when Chicago zoning code becomes a nighttime party promoter.
