The church building is in the
Romanesque Revival architectural style and was built under the direction of architects
Henry Stuckey and William Weir. It is built of local
limestone mined from Palmer Place, with
slate roof tiles from
Willunga. In 1855 the
nave was extended on the western side by some . Stuckey was also responsible for designing a number of other Church of England churches and other buildings in the colony, including at
Hindmarsh (now
Holden Street Theatres),
Port Lincoln,
Clare (St Barnabas),
Penwortham (St Mark's),
Port Adelaide (St Paul's), Beaumont Rectory, Walkerville Rectory, and St Peter’s Church at
Glenelg. He also designed two buildings at
St Peter's College, and
Pirie Street Wesleyan Church. The church, rectory, and hall are all
heritage-listed with the former two appearing on the
South Australian Heritage Register and the latter appearing on a "local" list maintained by the
City of Adelaide. ==Organ==
