The main lobby of Si Melby Hall was updated and expanded as a part of the 2000 renovation project. An interior glass doorway was removed, making for a much more open area on the north side of the lobby. The north side of the lobby is now used for concessions and merchandise sales during home athletic events. The main entrance of the building is now on the south side of the building, through the Kennedy Center lobby.

A complete heating, ventilation and air-conditioning (HVAC) system was installed in the building during the 2000 renovation project, a much-needed improvement to make the building a year-round resource for the Augsburg community. The new doors and exterior windows are all extremely energy-efficient.

Ringing the lobby is the Augsburg Athletic Hall of Fame. The Athletic Hall of Fame was established in 1973 to recognize male athletes who have made special contributions to the college's athletic history. In 1989, female athletes were first inducted into the Hall. Recipients are chosen each year on the basis of performance in Augsburg athletics, service to the school, civic and professional achievements and leadership. Recipients are honored at a Hall of Fame banquet during Homecoming week.

In the center of the lobby is Augsburg's main trophy case, showcasing the school's national championship trophies in wrestling and other accomplishments by our various athletic teams. Next to the trophy case are plaques honoring alumni Lute Olson '56, Ernie Anderson '37 and Edor Nelson '38, and other honor plaques. On the east wall is a jersey from the New York (now New Jersey) Nets worn by Dan Anderson '65, the first Augsburg athlete ever drafted by an NBA team. He played for the ABA's Nets in the late 1960s.

On the west side of the main floor a classroom/meeting room, offices for the Health and Physical Education/Athletic departments, the A-Club alumni organization and the football coaching staff. All were renovated in both the 2000 and 2006 construction projects.
