[3] 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.

All buildings on the campus are built in the Colonial Williamsburg style of architecture.

On September 25, 2011, the STEM Academy, designed to resemble the nearby North Carolina Research Campus Core Lab, held its grand opening.

This center also provides an Exceptional Children's Department, Dance Studio, Art Studio, Drafting, Culinary Arts, Foods 1 & 2, Theatre, & ROTC to the students of A. L. Brown High School.
