In 2010, Petra completed the ground-up construction of a 25,000 square foot tilt-up concrete campus building. The structure includes four wings containing 16 large classrooms, administrative offices, and a lobby with 2-story atrium.

Additional work was done at the school in 2021 which included the conversion of a storage room into Pre-K restrooms and library into a 5th grade classroom.

In 2022, a campus expansion featured extending two building wings by 3,100 square feet each plus build-outs of new classrooms, administrative offices, and storage areas.
