The Common Central Secretariat (CCS) buildings in New Delhi house several key ministries and departments of the central government. Strategically located along the Kartavya Path, they form a vital component of the broader Central Vista Redevelopment Project.
A distinctive architectural feature of the three CCS buildings is their innovative courtyard canopy. This design incorporates twenty-three lenticular trusses spanning 40 metres across the shorter axis, supported by bracing trusses along the longer axis. The canopy consists of 264 perforated aluminium panels, each measuring 3m x 3m. They are designed to create a comfortable microclimate within the courtyard. These panels filter sunlight to produce a dappled effect, enable uninterrupted airflow, and allow rainwater to nourish the space below. Such conditions are ideal for supporting the growth of large trees, offering occupants a shaded, tranquil retreat during Delhi’s intense summer heat.
