Immaculate Conception Parish is located near O’Fallon, Missouri. This area west of St. Louis has seen enormous growth over the past few years. This growth has generated numerous needs for the Parish, including additional school facilities.

The project consisted of the addition of twenty four new classrooms including art, science computer and music. A new library and school offices were also added. Portions of the existing school were renovated as well. Because of the continuing growth of the area, the design included provisions for the addition of another wing containing eight additional classrooms.
