As Mexico City continues to add population, multiple factors and constraints pushed development and irregular settlements to hillsides of the city’s peripheries. Current informal urbanization pattern lacks infrastructural provisions and open space, which further increases social inequality. This project introduces a pre-emptive approach, a topographic landscape strategy that acts as an open space armature for future development on hillsides of the city. It brings together social, ecological, economic, and cultural amenities that support and sustain the inevitability of informal growth pattern.
