The Saint Louis School Center, High School SLSCHS is located at Naguilian Road, Baguio City. The ICM Sisters decided to build a new structure to house their laboratories, home economics, function halls, carpentry, library, and a chapel. This was built in 2006-2007. The location of this building is at the sloping area at the perimeter of the property. The concept is to follow the slope with less earth movement. That is why the basement has the least floor area, and gradually increases as it gains more space at the higher elevation. This is a 2-storey structure with 3 basements. This is also the alma mater of Arch Mylen Yaranon wherein she offered her architectural services.
