St. Paul's College bloomed quickly in the late 20th century. In 1979, the completion of St. Paul's College Alumni Association Tse Yu Chuen Swimming Pool marked the completion of one of the greatest building projects of the decade. Its construction was made possible by funding from parents, older boys and the Alumni Association. In 1992, St. Paul's College was the first aided school to opt for the Direct Subsidy Scheme (DSS). However, the scheme was eventually suspended when the government policy changed. Under DSS, the school would have been given maximum freedom with regard to curriculum, school fees and entrance requirements. St. Paul's College Primary School was relocated to Hill Road in 1993, which formerly housed a secondary school. The vacant block at Bonham Road was transformed into a series of special-purpose rooms including an art room, music room, staff room, teaching resource room, computer room and teachers' common room.
