the exterior walls remained intact. The Mansard roof and square tower were destroyed in the fire. The university rebuilt the hall the following year, and used the original plans that included the round cupola but omitted the Mansard style roof and the square tower topping the structure. Architect Fred A. Legge oversaw the rebuilding and re-design of the hall. A campaign launched in 1920 by the university was set to raise $100,000 to be used for the reconstruction of Waller, plus completing the new Lausanne Hall and adding a central heating plant. There was some discussion of demolishing the hall in the 1980s after the structure had become dilapidated. One proposal called for building a replica on the same site as the original, but school administrators opted to renovate Waller Hall. From November 1987 to November 1989 the building went through a $2.26 million renovation. This renovation addressed interior issues with the building including seismic upgrades in the event of a large magnitude earthquake. These renovations also turned the attic into an office suite for the school's president. After renovations in 1988 the building was used for university administration offices. Further renovations were completed in 2005 at a cost of $1.3 million for upgrading the 100-year-old windows to newer energy efficient models, repairing the brick, fixing leaks, installing skylights, re-painting, and slightly lightening the exterior red-brick coloring. Architecture Waller Hall was built in the Renaissance style of architecture. This red brick building was designed in the same proportions as a Greek cross. Bishop Janes was responsible for proposing this use of the cross shape for the building. Each of the two wings is long and wide with aedicule porches on the west, east, and north ends of the building. Originally, the building was tall as measured from the base of the building to the top of the dome. The distance from the eaves of the structure to the base is . The basement of the building is high and the first floor high. The foundation is made of stone and the roof has composition shingles. Both the second and third floors are tall. The hall has a cupola topping the structure. Other details include pilasters, dentils, and brick corbelling on the exterior and circular stairways on the interior. Currently Waller Hall houses alumni relations, the school's business office, human resources for the university, the office of communications, university relations, the
