"The 'Makoko Floating School,' a triangular form in section constructed with a parallel series of timber A-frames on a platform supported by emptied blue barrels. The 3-story structure contains classrooms on the middle level in enclosed volumes flanked by public green space and playground below, and an additional open-air rooftop classroom above.

Slender wooden slats create a shading device along the outer envelope along with well-ventilated spaces to maintain a comfortable interior environment.…"
