The two-story dormitory and school measures 72 feet by 36 feet. The first floor is of horizontal round logs, dovetailed at the corners, while the second floor is wood framed and covered with wood shingles. Three triangular dormers decorate the front of the building, as does a Rustic porch across the center portion of the front. There are brackets in the eaves of the gables.
The first floor contained a chapel, dining room/school room, and kitchen, while the second floor had bedrooms. Since the mission closed, it has functioned as a pool hall and movie theater; it is currently vacant. In the mid-1960s one third of the building was converted into a gymnasium, and the second floor was removed.
