The nearly century old main building of the college also hosts two other colleges. The building is home to the Syamaprasad College from 5 pm onwards. Conversely, from 6:10 am to 11:30 am the building hosts the all-girl Jogamaya Devi College and from 10 am to 5 pm, the co-educational Asutosh College. This system is common across Kolkata and some other cities in India.
