Over the course of the schools history, many additions have been built on to A. L. Brown, such as a separate vocational building, as well as a free-standing gymnasium. During the 2006–07 school year, a newer gymnasium facility opened on campus. These free-standing buildings give A. L. Brown its unique character. Instead of a traditional single building like most high schools, Brown has a small, college-like atmosphere with numerous buildings around a central courtyard. All buildings on the campus are built in the Colonial Williamsburg style of architecture. They also are brick with white trim, modeled after most of Kannapolis.
