By 1916 the Junior (now Psychology) and Refectory Buildings were completed, but the Administration Building was only two storeys high in the central part and one storey high in each of the wings. All three original buildings, and the Central and Chapel buildings, are brick-faced with matte-surface Greendale bricks, with Indiana limestone or terra cotta trimmings, and set on Montreal limestone. Further construction on the Administration Building was done in stages as funding became available. In 1920-21, at a cost of about $300,000, one storey was added to the central body of the Administration Building, and two storeys were added to each of the wings, for a uniform three storeys. It was not completed until 1927, when two additional storeys and the tower were added. Architects Peden & McLaren had prepared a grand plan for the campus in 1913. The original plans were only partially realized for lack of funding. A planned swimming pool in the Administration Building was eliminated to reduce costs.
