Kjelsås School was originally built in 1917 during World War I to replace an earlier 1881 school building that had become too small for the growing student population. The school has undergone multiple expansions and renovations throughout its history, including major additions in 1933, 1959, and 1979, before receiving a complete renovation that was completed in 2012. The school's elephant sculpture in the courtyard was created by a staff member using mosaic pieces made by former students.
