atarpados

Atarpados is a term used in speculative urban studies to describe a form of informal vertical living in which residents construct and inhabit terraces atop abandoned or repurposed urban infrastructure, such as elevated rail lines, bridges, or building supports. The concept emphasizes self-reliance, communal governance, and adaptive reuse of space within dense metropolitan areas. The term’s etymology is debated; some scholars link it to local language roots suggesting a sense of being “placed on supports,” while others treat it as a neologism coined by urban researchers.

Origins and usage: The notion emerged in comparative field notes and documentary projects in the early 21st century. Although not widely codified in official statistics, atarpados has been used to frame discussions about informal housing, resilience, and urban improvisation in crowded cities. Geography: Documented instances have been reported in several megacities where formal housing supply is limited and informal settlement activities are observed, often near and atop aging infrastructure. These cases vary in scale and governance, from small communal platforms to larger networked ensembles.

Architecture and living conditions: Structures are built from salvaged materials and built through collective labor. Terraces are connected by improvised stairways and handrails, with water collection, composting, and small-scale agriculture sometimes incorporated into the design. Social organization tends to be communal, with rotating leadership and shared maintenance responsibilities, though projects differ widely in governance.

Impact and policy: Proponents highlight resilience, social cohesion, and productive reuse of underutilized space. Critics warn of safety hazards, legal ambiguity, and potential displacement. Urban planners and researchers debate whether to formalize, regulate, or relocate atarpados communities as part of broader renewal strategies.
