This research explores the formal and structural evolution of dodecahedral geodesic structures, proposing configurations that maintain their geometric essence while allowing continuous lateral growth without losing spatial unity. These innovative proposals open new perspectives in the field of lightweight structural design, standing out for their adaptability and coherence. The methodological approach combines theory, digital simulation, and practical experimentation. It begins with the analysis of dodecahedral geodesic structures and their geometric evolution, identifying combinations that enable significant transformations without compromising structural essence. Digital simulations are then used to evaluate configurations that allow continuous lateral expansion. Finally, full-scale physical prototypes are built to validate structural stability and flexibility under real conditions. The results demonstrate that the proposed configurations maintain the dodecahedral geometric identity while enabling indefinite lateral growth. The physical prototypes verify their stability, lightness, and adaptability to different architectural contexts. This structural evolution promotes sustainable designs that meet contemporary demands for lightness and versatility. In addition, the proposal integrates playful methodologies into educational projects, fostering creativity and structural thinking in students. Learning through hands-on experimentation strengthens the understanding of the geometric and structural possibilities of dodecahedral configurations, promoting innovative and participatory training in the field of lightweight structure design.
