Our Lady of Lourdes consists of four buildings: a church, rectory, school, and convent. The church is a steel-frame structure clad in brick, designed by Ambrose Murphy and built in 1925. The rectory is a two-story brick structure with hip roof; it was built in 1912. The original rectory, built in 1905 to a design by Walter Fontaine, was converted for use as a convent when the new rectory was built. The school building, also built in 1905 to a Fontaine design, is the largest structure in the complex, and originally served as both school and church until the student population grew too large for the educational facilities.
