The building underwent significant renovations in the mid-1990s and on April 1, 2003, residents of Community Unit School District 200 approved, by a vote of 10,173 to 6,518, a $72 million bond referendum to renovate and add onto both Wheaton North, and its counterpart, Wheaton Warrenville South. Construction began in the summer of 2003 with its first phase of the building of a field house. The second phase included renovations and additions to the building, which were completed in summer 2006.
