The design intention is to create a public space that changes its place with the different water levels. A concrete grid structure, which reaches the high flood level, is the base of the units. In dry season, public life takes place in the streets on the ground and between the concrete structure. The space under each unit is used to sell own products from the workshop one story up or can be rented out for other public uses, creating a market beside the streets. Between the units, courtyards give the possibilty of shared pekarangans. During rain season, when the lower space is flooded, the grid structure is used to set up temporary streets and connections between the buildings. These streets on the high flood level form the public space during the three months of rain season. The selling is shifted to the balconies.
