The southern edge of the sunken courtyard is articulated as an engineered wetland calibrated for seasonal performance. In the rainy season the wetland operates as a retention basin and reflective landscape, attenuating runoff and enhancing microclimate; in the dry season the planted terraces become accessible learning platforms with diverse textures and microhabitats. The wetland is programmed as a living laboratory for environmental science, hydrology, and ecology; its sequence of wet and dry conditions provides direct, repeatable observation opportunities for curriculum integration.

Framing the wetland, a street basketball court and stepped terraces form a flexible activity arena. These terraces mediate level change, provide informal spectator seating, and create sheltered microclimates that extend outdoor use across seasons. The courtyard ensemble supports daily physical activity, spontaneous performance, and informal assemblies, embedding sport and social interaction into the campus’s daily routines.
