Think hydroelectric dam and very little precedence comes forth to imagination. Block wall, stops water, lets a bit fall out in a big cascade, useful. The very aesthetic of most hydroelectric dams read as just that; one can read exactly how it works from how it's built.
Becker Architekten begs to differ. Somehow they have twisted utilitarianism to a thing of beauty and, what I think it is more important, mystery. Makes us think twice about any structure worth its weight in utility.
