In 1963, another school building was constructed adjoining Holy Family Church. It was improved and extended with the help of student efforts such as donations, raffles, and school fêtes. A new hall and classrooms were constructed. This building lacked facilities such as filtered drinking water and a cafeteria. It had an inadequate playground and poor sports facilities, requiring the use of the Vinayalaya Jesuit seminary grounds, behind the school and church buildings. The building was extended in the 1970s to have multiple stories, with additional classrooms and a school hall. The school had female students for a few years. Some were admitted for year 11 science and commerce streams. Earlier in the school's history females were accepted at lower levels as well. A mini-stadium was built on the old school ground using funds donated by Jitendra Shah. A few years later, the building became too small to cater to the growing number of parishioners and the building was sold.
