This chapter delves into two distinct categories of public/collective spaces that significantly impact metropolitan dynamics, albeit differing vastly in their modes of utilization, temporal and spatial characteristics, planning processes, motivational factors, and user freedoms. The first category encompasses macro-artifacts, large, peripheral shopping centers, intricately linked to major infrastructures and highway intersections, structured around regional polarization principles. The second category encompasses a myriad of micro-artifacts, including street vendors, mobile bars, clandestine dining spots, garage sales, impromptu events, artistic interventions in unconventional spaces, pop-up stores in abandoned buildings, makeshift cinemas in parking lots, and self-managed gardens on vacant plots, among others. This chapter endeavors to explore the intricate interplay between these seemingly contrasting logics in contemporary urban development. It examines how the appropriation, reconfiguration, and reinterpretation of public space at a metropolitan scale are shaped and influenced by the presence of these two categories of commercial spaces. Ultimately, the discussion highlights the pivotal role of these logics as transformative agents in urban planning, particularly in the reorganization of the public space network, serving as catalysts for profound societal change.
