This system was developed in the late 1970s when the prefabrication of reinforced concrete structures was at the height of its popularity. Prefabricated concrete "containers" are stacked on top of each other - each layer oriented perpendicular to the one directly below it. This results in a criss-cross pattern that also gives it a degree of stability. The main difficulty with this system is the lack of a logical clarity or regularity for the building systems.
