"Generate a conceptual volumetric model for a university hospital tower for the UAM Xochimilco, composed of three interconnected volumes of varying heights, with a maximum of five levels above ground. The design should emphasize the conceptual stage, using simple, abstract geometries rather than realistic details. General Volumes: The three volumes should have different heights to create dynamic visual interest and maximize the use of rooftop terraces for green spaces, relaxation, or additional functional areas. Arrange the volumes to create a sense of connection and hierarchy, reflecting their distinct hospital functions. Functional Organization: Tallest Volume (5 levels): Primary medical functions such as surgery and ICU. Medium Volume (4 levels): Spaces for hospitalization and outpatient services. Shortest Volume (3 levels): Public-facing areas, including emergency services and academic/research spaces. Connect the volumes through bridges or overlapping forms, emphasizing accessibility and collaboration between areas. Design Aesthetics: Use clean, abstract shapes (cubic or rectangular) to represent the volumes. Incorporate setbacks or cutouts to suggest terraces at different levels, optimizing natural light and ventilation. Show rooftop terraces as green placeholders, highlighting sustainability and integration with nature. Urban Context and Sustainability: Arrange the volumes compactly to reflect the constraints of an urban site. Include placeholders for sustainable features like green roofs, solar panels, or rainwater collection systems. Emphasize efficient use of vertical and horizontal space while maintaining open, collaborative connectivity between volumes. Focus on exploring proportional relationships, the hierarchy of volumes, and the potential for terraces and interconnected spaces. The model should evoke the concept without relying on realistic architectural detailing."
