Torre Negra is a laboratory building designed for the Universidad Autónoma de Durango, conceived as a compact, permeable volume that balances environmental performance and architectural expression. A dynamic metal façade regulates sunlight, ventilation, and shadow while subtly transforming the building's perception throughout the day. Exterior circulation systems create an intermediate spatial experience between interior and exterior, redefining educational infrastructure as a precise, atmospheric, and contemporary architectural object within the campus.
