Chandni Chowk, one of the oldest designed streets in Shahjahanabad, stretches from the Lahori Gate of the Red Fort to the Fatehpuri Masjid and has served as a central boulevard since Mughal times. Over centuries, it adapted to the needs of successive rulers and planners, but in recent decades it has suffered severe decline. The project aimed to reinstate Chandni Chowk as a vibrant marketplace while restoring its architectural integrity. The conservation plan was based on an in-depth study of the street’s significance, issues such as traffic congestion and service upgrades, and recommendations for restoration, repair, and new development. The process involved archival research, detailed documentation, mapping, and analysis, resulting in a vision and strategy that later informed the urban design of the public realm.
