Fourways High School opened in 1988 with 145 students and 8 teachers. As the school was so small at that time, only the B Block was used and there were only Standard 6 (Grade 8) and Standard 7 (Grade 9) classes. The first matrics matriculated in 1991. Initially there was no school uniform and the pupils came to school in civvies. There were no lawns, gardens, trees or sports fields.
Students, parents and teachers worked together to lay out gardens and plant trees and the plants and trees in the Quad are still the original ones planted at that time. As the school grew in size, the following facilities were added on: A Block, the Auditorium, Pavilion and the Swimming Pool.
