At Yani House, this project focused on the behavior of rain generated by the configuration of the roof and the engawa (veranda). During heavy rainfall, water flows along the corrugated roof panels and falls to the ground at regular intervals. These droplets are guided into a shallow channel, where they reappear within the viewer’s field of vision. Through this sequence, rain forms a temporal structure that circulates within the space. To visualize this path of water, the project examined an apparatus composed of corrugated panels and channels. By controlling the points of descent and the direction of flow within a simple configuration, the intention was to transform the movement of rain into a continuous spatial phenomenon. As part of the experiment, a temporary roof was installed to test the control of falling water and the feasibility of guiding it into narrow channels. The use of corrugated panels proved effective in adjusting the drop positions and directing water flow. However, the experiments also revealed that the visibility of the phenomenon varied significantly depending on the height of the viewpoint. From a seated position on the engawa, the behavior of the water was difficult to perceive, indicating the need for adjustments at the foundation level. This project can be understood as an attempt to spatially extend the fleeting phenomenon of rain. At the same time, it functions as an experiment demonstrating how conditions such as viewpoint, material, and light are deeply intertwined with the emergence and perception of environmental phenomena.
