The Anglican Church proposed merging St. John's Hall with St. Stephen's Hall, a female-only hall, into the co-educational St. John's College (SJC). SJC subsequently moved into its new premises at 82 Pokfulam Road in 1955, leaving the whole premises at Bonham Road for St. Paul's College's use. The Wong Ming Him Hall, the oldest building existing in the campus nowadays, was built in 1951. The three-storey, multi-purpose building once housed a table tennis room, art room and music room. The building was renovated in 2007–2008 and now houses a multi-purpose rehearsal room, a board room and the archives. The college swimming pool, known in full as "St. Paul's College Alumni Association Tse Yu Chuen Swimming Pool" (聖保羅書院同學會謝雨川游泳池), was officially opened on 8 November 1979. The pool is next to the Wong Ming Him Hall and was named after the alumnus who initiated the fundraising campaign for its construction.
