Architectural Design V-IX: Urban Culture Infrastructure in Medellín (H.Klumpner)

Abstract

How can architects foster urban culture through infrastructure?How can climate corridors impact social and ecological resilience?How can we imagine the future of architecture in Medellín?

Objective

While cities contribute to the highest CO2 footprints, they also hold the potential to most effectively bend the carbon curve and take Climate Action in achieving the UN's Sustainable Development Goals. Moving towards decarbonized ways of living and `Making cities and human settlements inclusive, safe and resilient (SDG 11) will require behavioral and systems change in all sectors of life. Access to quality education (SDG 4), co-creating evolving frameworks for life-long learning, building capacity for transformative processes, strengthening and building new circular economies, making use of digital and analog tools, as well as how easy it is to access services in the city, are the foundation to design and maintain sustainable urban futures. In alignment with these principles, the central thesis of this Design Studio focuses on the conceptualization and design of innovative architectural and urban prototypes. These designs aim to address and respond to the complex challenges posed by green and blue infrastructure, climate corridors, informal settlements, urban densification, the circular economy, social sustainability, and the re-naturalization of urban landscapes. Through this approach, the Design Studio seeks to create solutions that meet immediate needs while contributing to the long-term resilience and vitality of urban environments. Students are introduced to tools and immersed in our Chair’s “method-design” to develop their prototypical design projects by: 1.) Base-Line: We design in a continuum of architectural, urban, and planning scales to collaboratively develop a basis for how the city is now. 2.) Mapping: By identifying existing and future challenges and opportunities, we take the role of stakeholders and visualize our demands and resources into three different scenarios. 3.) Concept Design: We develop an urbanistic synthesis and translate a concept into an evidence-based prototypical architectural project- intervention. 4.) Prototype Design: We present the synthesis of our process in time and space on different scales. We frame the design projects as a narrative, consequentially developed and communicated in analog and digital graphic representations. 5.) Upscaling: We test our project concepts and upscale prototypes through design-policy recommendations to make them transferable in Medellín and other cities. The design studio focuses on the transformative redevelopment of the city on three scales: A_Metropolitan Scale: 1:50.000 / Valle de Aburrá B_City Scale: 1:10.000 / City of Medellín C_Site Scale: 1:2.500 / Iguaná Corridor

By 2025, Medellín is set to become a global leader in environmental urbanism, with its Cinturón Verde (Green Belt) initiative linking 20 kilometers of green and blue corridors, transforming the city into a model of ecological integration and sustainable urban growth. Once known for violence and inequality, Medellín has reinvented itself as the pioneering city in urban regeneration. Today, it stands as a model of resilience, navigating the challenges of rapid urbanization while fostering social equality and environmental sustainability. As Medellín grows, balancing urban expansion with the preservation of its natural environment is crucial. The city’s green urbanism with the projects like the Río de la Vida and Cinturón Verde, restore ecological systems and incorporate them into the urban landscape. These green and blue corridors not only mitigate climate change impacts but also reconnect communities to nature. Medellín’s transformation is not only physical—it is rooted in social inclusion. The city uses infrastructure to reduce inequalities, exemplified by the Metrocable, which connects hillside communities to the city center, and the development of parks, libraries, and public spaces in informal areas. As of 2024, Medellín is recognized as one of the most innovative cities in Latin America, with over 50% of its public transportation system now being powered by sustainable energy. In response to these challenges and opportunities, the design task focuses on the La Iguana green and blue corridor—a water stream that begins at 2,900 meters and descends to the Medellín River at approximately 1,400 meters elevation. The central goal is to design strategies for linking fragmented urban and natural spaces, enhancing both ecological and social resilience. The design prototypes developed along this corridor must foster community engagement, promote environmental justice, and address the needs of vulnerable populations. As the city consists of 16 administrative communes, La Iguaná corridor can be seen as 17th. Medellín’s vision for the future—where infrastructure, public space, and ecological corridors work interconnected—demonstrates how cities can overcome past struggles and lead the way in sustainable urban development. Through these initiatives, Medellín sets an example of how urbanization can be approached in a way that promotes social culture, environmental restoration, and resilience for future generations.
