Three years later Edwin H. Tomlinson donated the adjacent property and $5,000 to erect a new brick church building.

An extension of the church building to the west and an intersecting double-width partial transept to the south was added in 1925.

The cathedral is masonry building composed of blonde-colored bricks with pink mortar joints.

There are two shorter towers on the southeast and northwest corners on the west façade that have flat roofs and crenellated parapets.

The stained glass windows feature depictions of the life of Christ, the Stations of the Cross, the sacraments, and the lives of the saints.

The main organ is located in the front of the cathedral with the pipework of Great, Pedal and Positive exposed and Swell and Choir division enclosed, and an Antiphonal division (consisting of the original 1915 Austin organ) in the rear of the cathedral.

[6] In 2016 a new Antiphonal division was added by the Patrick J. Murphy & Associates Pipe Organ Builders, retaining one rank from the original 1915 Austin pipe organ and moving the original "Trompette en Chamade" located on the cathedral arch to this renovated division, increasing the number of ranks to 64.
