Vladimir Dianiska, Anna Gebhardt, Basil Witt_Midterm Review_River Niches

Our project takes the Ciliwung river as the vital link which runs through the city of Jakarta and connects its districts. The river will not only connect the people but also serve as an economical driver. The Kampung scale is defined through an alternating series of urban „pocket“ spaces and green zones along the riveredge. The „pockets“ host a new building typology on stilts which allows the water to flow underneath it, thus giving the river more space. The riverbed gets widened as a result of our interventions and has a controlled water level for the transport. The housing on dry ground is conceived as a terraced system connected with stairs. Basically an artificial hill. The idea is to build within the existing stock only replacing buildings which are in bad shape. The implemented new structures are a basic framework and can be taken into possession by the inhabitants in various ways.

Through adjusting the topography we can give the river more space, lower the flood levels and thus protect the inner area around the mosque. This is achieved by a step-by-step approach. Up to critical height, the structure is built out of concrete pillars and slabs. On top of this given structure, houses can be built in light-weight materials to allow more flexibilty. A temporary 2nd street level ensures the accessability of each unit during flooding.New pedestrian connections (bridges) between the two blocks improve the accessibility of the lower block to schools and other public services and shorten everyday distances. The river edge is broadened as natural habitat. With pekarangans and fishponds, the green river edge finds its way into the block.

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. During rain season, when the lower space is flooded, the grid structure is used to set up temporary streets and connections between the buildings. New pedestrian connections (bridges) between the two blocks improve the accessibility of the lower block to schools and other public services.The river edge is broadened as natural habitat. With pekarangans, the green river edge finds its way into the block. Through slight changes of topography the inner block is protected from flooding.

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.
