Since India's independence in 1947, it housed the office of the Chief Minister of West Bengal, cabinet ministers and other senior officials, until 4 October 2013, when a major restoration of the building was announced. The majority of government departments were subsequently moved out to a new repurposed building named Nabanna in Howrah on a temporary basis. The building has been called a mini-township of sorts with a built-up area of around 550,000 square feet. Before the shifting of the state secretariat, the building housed 34 departments of the state government, and served as the office for approximately 6,000 employees. As of October 2020, the renovation of the building continues.
