Beirut, Lebanon

IC Elementary School

Elementary School building is part of the International College in Beirut, which was in 2013 the first LEED Gold building in Lebanon.


The project consists of three interlinked school buildings of 3 to 5 floors, each with a basement for parking facilities, totaling around 22,670m2. The three buildings are connected on the ground floor and through the parking area. This new elementary school houses classrooms, music rooms, art rooms, science labs, workshop areas, offices, an auditorium/theatre, and two gymnasiums. The building complex also houses the central heating, as well as the cooling and power generating plants for the College.
