It appears to have changed very little since it was finished. The oldest part of the structure was a two-story rectangular block at the corner of Stonewall and College streets. In 1913-14 this was increased to the present three stories. At the same time, a three-story trapezoidal wing was added next to the original unit on the College Street side. Its angled rear wall conformed to the railroad track, now taken up, that curved next to the structure.
Walls are of brick laid alternating five stretcher courses with a single header course.
They extend up above the roof line to form a parapet capped by terracotta tile. Inside the building a brick wall divides the old and new wings. All exterior brick and most of the interior brick has been painted. Windows are twelve pane steel frame units, with a center panel that swings out for ventilation. These window units are decades old, but likely are not original.
