In many flood-prone and riverine areas across Latin America, communities face chronic exposure to rising water levels, limited access to safe water and energy, and infrastructural neglect. These territories lack the basic systems needed for dignified and resilient living. Environmental risk intersects with social inequality, producing conditions where conventional architecture and planning tools are insufficient or inapplicable. The project responds to this context by presenting a self-sustaining floating platform that integrates rainwater harvesting, solar energy generation, and basic hygiene infrastructure. Built with modular wooden components and locally sourced materials, the structure is designed for low-cost, community-led construction. It demonstrates how architecture can operate as a decentralized system for survival, autonomy, and infrastructural justice in contexts of environmental and institutional precarity.
