The church is a one-story rectangular brick building with a gabled front. The church, which was built in 1891, is symmetrical in design with a central entrance on the west elevation. The building rests on a coursed stone foundation, with a belt coursing of brick at the water table level. The hipped roof is covered with asphalt shingles.
A short wooden steeple rises above the west gable and emphasizes the entry to the church. The steeple is octagonal and has wooden, louvered vents. Patterned metal siding panels now clad the sides of the steeple, and the octagonal roof is crowned with a metal cross. The main entrance is set under a gothic arch and has been altered. The original double entry doors have been replaced, however, the amber glass banding above the door remains. The window opening in the gothic window is now infilled with plywood that bears a non-historic crucifix. The steps have been replaced with poured concrete and heavy poured cement railings. The granite cornerstone rests above the foundation on the southwest corner of the main facade. The simple granite stone shows the date of dedication as 10 March 1889, and an engraved cross that sits midstone separates the day and month from the year. In keeping with Catholic tradition, religious relics may have been placed inside the cornerstone when it was laid.
The gothic arch is trimmed with a projecting molding of brick, and this pattern repeats on the windows on the north and south sides. A small brick-framed round window placed directly above the door entry is now filled with plywood. Holy Parish Church is working to replace the stained glass in the small window.
On the north and south elevations, four single gothic windows are symmetrically placed along the building length. Window heads are infilled with plywood, and the units appear to be the original 2-over-2 double hung windows, glazed with milky white and yellow glass. Segmental brick arches span the basement windows. On the north side, the brick chimney rises above the roof.
The inside of the church has been remodelled, but it still retains the original basic design. The small entry-way to the church has a cloak room and the stairway to the choir balcony. The balcony is a small rectangular-shaped area with an organ and pews for the choir. The church is a large open room lined with windows. The walls and ceiling are painted white, and the ceiling was lowered. A sanctuary behind the alter is used to store the vestments.
