The main church building is a large structure of red brick with red sandstone trim, designed by Martin & Hall and built over a 25-year period ending in 1915. The rectory, located east of the church, was designed by Ambrose Murphy and built in 1924-25, and is also faced in red brick. The convent stands west of the church; it is a 3-1/2 story red brick structure also designed by Murphy and built in 1929. Behind the convent stands the school building, which faces Gordon Avenue. It is a two-story red brick building.
