This project aims at creating a vibrant atmosphere with density structures for visual curation on the purpose of maintaining the vibrancy during heavy rain period when due to the water clogging, it is hard for people to come to experience the vibrant life. The density structure varies from 15% to 100% visual permeability according to the sightlines related to the specific space which houses corresponding user group and their activities and the specific boundaries by rotating the layered slices. The elements take consideration of Japan coastal life - Kawadoko restaurant typology, which the view from the inner eating loge to the elevated terrace to the quay (which has some outdoor activities like fishing, walking, buskers, live performance, etc.) to river water, is remarkable and celebrating the river entertainment life. The final outcome is a space with the combination of formal and informal restaurant and coastal activities to let both workers (such as cooks for street food cart) and customers (such as businessmen taking their foreign clients to experience local culture and make a deal) not disturbed by the water clogging and be affected by the vibrant atmosphere with visual curation of the density structure
