Margaret Street Methodist Church - as it then was - was established in 1838. The first minister was Rev. J. A. Manton. After several buildings were built fronting Margaret Street, the present church building in Balfour Street was built in 1889 to a design by noted architect Alexander North.

It was originally built as a Sunday School, a simple Hall with a gallery on three sides and classrooms on the second floor.

In 1918 the pipe organ was installed in a choir bay which was added, and is now the worship centre, and the seating was turned and rearranged in the present radial layout.



After the formation of the Uniting Church in 1977, Margaret Street joined with St Stephen's Presbyterian Church, and later the name was changed to Trinity Uniting Church.

A peculiar feature of the building is that the original part of the structure is rhomboidal rather than rectangular (as it appears), seemingly because it was built parallel to Margaret and Balfour Streets, which meet at an acute angle.
