Multihalle, Mannheim, Germany by Tatsuya Krause
One of the most important facts about the Multihalle is the generation process of the pavilion, based on a Gridshell.
Frei Otto developed a Gridshell form finding process that involved hundreds of scale models of Gridshells. He developed a catalog with several forms and shapes that the Gridshells can generate when hanged. Just like Gaudi, Otto worked on scale models to see the behavior of the grid he was working on. The studies he did were about form and shape but also involved architectural basic needs, as space and light.
