The building is designed for LEED Gold certification for energy efficiency and modern mechanical and ventilation systems. The gymnatorium and the cafeteria are located on the first floor for ease of access by the surrounding community after school hours. The construction process began in December 2021 and reached substantial completion by October 2023.
