In 1894, a new building, the present red- brick structure, was erected under the direction of Br. Joseph Moyes and is now St. Joseph's College, Bow Bazar . This became the Head Office of the Christian Brothers till it was moved to St. Columba's School, New Delhi, in 1980. The work that the Brothers were doing received recognition and requests came from several Catholic Bishops for the Brothers to open schools in their dioceses. At the turn of the century - there were nearly fifty Brothers in India, both Irish and Anglo-Indian, and a training house for Brothers (novitiate) was started at Mt Carmel's, overlooking Goethals.

St. Joseph's College was affiliated to the ICSE and ISC Boards in the year,1970. In 1994, Aashirvaad Vidyalaya, a bilingual school for the children of migrant workers, was opened on the St. Joseph's and St George's campuses. St. George's School is a tuition-free school which is run and managed by St. Joseph's College providing quality education to those who cannot afford it. The books and uniforms all are provided for by St. Joseph's College.
