Within 10 years of the 1874 completion the question of size was raised. Attendances at services had grown and on special occasions hundreds were turned away. In 1886 Bishop Barry said enlarging the cathedral was a question to face. He suggested the possibility of doubling its size. During 1883 proposals were made for a suitable memorial to Bishop Barker the second Bishop of Sydney. The chapter house was decided on, to be also used as a synod hall. This suggestion was aligned with Barker's advocacy of synodical government. The building was designed by the Blacket Brothers and was opened by Lord Carrington and used for the first time at the general synod in October 1886. In the meantime, St Andrew's Cathedral School was established in 1885 to provide choristers to sing at daily services, a strong tradition that has continued.
