The special condition that is generated by the transit of a river through a place becomes the cause for the design investigation of a space that aspires to become an amplification field of water properties (weight, levitation) and of its behavior (movement, liquidity) in order to multiply the experiences that these properties can transfer to the visitor. The participation of the water is the key element in the theoretical and design level, and its action is incorporated not only in the forming procedure but also in the function of the compositional space.
