Patrick O'Kelly established the Saints Peter and Paul parish, which is now St. Augustine Church.

He came to Detroit in 1829 and served various parishes around the diocese before being appointed as pastor of Oakland and Livingston counties in 1843 and founding St.

[3] The Saint Augustine Church is a rectangular red brick Gothic Revival building on a high foundation of random ashlar, which extends to the base of the windows.

The opposite corner of the facade contains a slightly projecting end bay with a side-facing gable at the top, creating some visual balance to the tower.

Cornices, Gothic "tracery" treatment in the front gable, and hood moldings are made of galvanized iron.

Inside, the vestibule area contains staircases leading to the basement, and access to the original front entrance, through which a small lobby opens into the nave.
