The De La Salle Brothers also bought a plot of land in the area, and is now occupied by St. Patrick's School.

The beginnings of its actual structure only came about shortly after World War I, when Reverend Father Pierre Raudel, the then-parish priest of the Cathedral of the Good Shepherd, approached Scheerder for the donation of some land in Katong to build a chapel for the growing Catholic community in the area.

In 1969, to better accommodate and service the increasing number of Catholics in the area, the church again underwent renovation and extension work which was completed by April 1970.

The church hall featured a single large crucifix on a blank wall behind the altar, and this set-up was often decorated with paints, banners and other artwork, changing to appropriately suit the missal theme of the week.

Thus, it was again demolished on 29 December 1997 to make way for the current, larger, 4-storey church building led by the then parish priest Rev.

The centrepiece is the altar with a massive 16-panel stained glass above, depicting the Holy Family and 16 scenes from Jesus' life.

3 Sea Avenue was donated by a parishioner after his death, as he had stated in his will to pass the deed of the building to the church.
