Zero-to-Zero

Zero-to-ZeroAn Open Framework for Production, Habitation, and Ecological Repair

The city hides the systems that sustain it. Zero-to-Zero builds with them.

Located on Madrid’s southeastern edge, Zero-to-Zero brings three conditions into one spatial framework: La Cañada Real, one of Europe’s largest informal settlements; landscapes shaped by decades of waste processing; and speculative high-end urban expansion.

Recyclable material collected across Madrid is sorted and transformed on site into structural components, building elements, furniture, and small products. A truss-and-crane framework grows outward from the production hub, allowing housing and public programs to be added, removed, or relocated over time.

Type A combines material recovery, employment, and housing. Type B carries agricultural, research and support programs between clusters. Type C forms linear phytoremediation corridors across contaminated land. Together, the three types connect livelihoods, material cycles, and ecological repair within an adaptable urban system.
