The study presents a morphogenetic approach to architectural design and structural analysis applied to complex sites and structures. As a Case Study, the research focuses on one of the facilities of the Río Tuna, a community tourism center located in the Amazonian foothills of Ecuador. The project explores the dynamic relationship between architectural form and structural behavior through the integrated use of manual design and computational tools. The selected two-story building features an organically curved roof whose geometry emerged from contextual parameters such as canyon topography, dense vegetation, and environmental orientation. The workflow combined manual exploration with computational tools: Rhinoceros was used for parametric surface modeling derived from hand-drawn spatial interactions, while ETABS enabled structural simulation and iterative optimization. This integration strengthened responsible construction by reducing potential geometric inconsistencies, optimizing material performance, and enhancing sustainability through early-stage feedback between form and forces. The resulting steel and reinforced concrete system achieved stability under vertical and seismic loads in accordance with national and international standards, maintaining deflections and torsions below permissible limits. The findings demonstrate how form-finding and digital simulation enable efficient and context-responsive morphologies, providing a framework for sustainable architectural development in seismic and tropical regions such as the Amazonian basin.
