Multiple changes, tweaks, and additions have been made to the structure of the school, notably the construction of Hamilton (1963) and Clark (2011) halls.

The 2000 addition is known as Jefferson Hall and was built to replace the previous C Building which stood where the entrance to the stadium is today.

[This paragraph needs citation(s)] The construction of a new high school was begun in August 2023, and one of the main reasons was the population growth of Columbus, an issue that can be seen throughout many areas of the city, including Gahanna.

The new high school will have a larger student capacity, more open learning space, and multiple "prides", which will be used for one-on-one and cross-course lessons.

The high school offers the following sports: Boys: Cross Country, Golf, Football & Soccer in the Fall; Basketball, Wrestling, Swimming, Bowling, & Ice Hockey in the Winter; Baseball, Track & Field, Tennis, Volleyball and Lacrosse in the Spring.

A new synthetic turf athletic field was installed in 2008 and replaced in 2018 to allow many sports to be played in the main stadium, including football, soccer and lacrosse as well as uses by Physical Education Classes, marching band and other teams for conditioning.
