As a first step towards a more flood resistant landscape, we propose to widen the river to about the double width. We propose a park on the tip of the peninsula, that continues along the southern river edge. The whole river has a steeped edge with a pathway and trees on top, in order to prevent people from reoccupying the area towards the river. It also changes the river from its function as a place for sewage and garbage discharge in the backyard of the poor houses towards a public space.
The Unit Meets The Block The unit-toolbox is now ready for action in the block. The modular units occupy now a parcel of land right next to the Ciliwung River behind the proposed greenbelt. In this frequently flooded area the ground floor contains just contemporary that can easily change its location during flood season. The ground floor also provides space for a sewage water treatment unit. Housing takes place in the higher levels. The different flats share one staircase unit and wet-wall unit, but every flat has its own bathroom an kitchen.The building cluster is two-sided. On the one hand the living units face the streets and the river bank and on other hand the private balconies and terraces face the inner courtyard.
The more common block is already very urban and should be densified even more by inserting our units in free spaces and by heightening the existing houses. We want to push the urbanisation as close as possible to the river and define a new river edge. The block has been divided in several sub-blocks having a water tank in each collecting the rainwater from the roofs, containers for the garbage collection and a small pipe system, collection the sewage water from the houses discharging into a clarification plant. For the block with the old railway depot the aim is to develop a natural habitat, a recreation zone for the inhabitants and to convert the railway depot into a new railway station and public cultural and community center. The river edge has been modified removing the unsafe housing close to the riverbank and replaced by a green belt.
The concept for the section evolved directly from our terraced unit. The terraces were extended and used as a an artificial topography creating different situations to meet, to sell local products or just enjoying the river scenery on different levels. Establishing versatile visual conjunctions was a very important issue for the concept. On the right side the section is more urban with integrated small shops inside the volume of the terrace system. On the lower levels these shops can be directly tied to the use of the river. Fish and water related agricultural products can be sold here. On the left side of the section a series of terraced gardens are leading down to the river. The soil is stabilized through brick or concrete walls and the vegetation of the gardens. The walls lineary run along the river serving as flood breakers and pathways. The accessibility of the river is on both sides guaranteed through a simple wooden footbridge structure. Here we wanted to make the river less deep so artificial fish ponds can be installed.

Through a shortcut in the course of the Ciliwung River, the yearly flooded area in the middle of the Kampung becomes a detention basin. A network of paths makes sure that the area can be used as a recreation zone. After the restoration of the ground, the area serves for agricultural purposes and fishing (Wadocks). In consideration of the existing streets a new subblock system is introduced. Each subblock solves its rainwater collection autonomously in its semi-private courtyard. The sewage and garbage collection takes place in a building, which is close to the main streets. The process leads to a dense residential area that offers a high quality of common space and has a positive impact on the development of the whole Kampung.
The structural concept is a concrete table on the ground floor. The upper floors consist of a lightweight bamboo framework construction and a concrete core with the infrastructure inside. Rainwater is collected and stored on the top floor and in central water tanks. Black water is treated by ultrafiltration stations. Garbage is collected in-house.The riverbed is enlarged the river edge will be lowered for a riverside-park, which in case of flooding can take 2.5 meters of water. The street network in the northern block will be extended and interconnected. The density shall be lowered in the northern and enhanced in the southern block. On the level of the first floor, a balcony interconnecting all buildings provides a safe traffic zone during flood time and connects the two blocks with a bridge. In each of the blocks, a new public square is implemented.
As of right now the river is perceived as dangerous and a place where the poorest of the poor live. This notion of the river has to be fundamentally changed in order to revitalize it and its bounding areas. This re-thinking is achieved by up- grading the river front buildings in an all new building structure. Through this measure people will learn again to appreciate the river and its river banks. In order to respond to the requirements for each block, we have to divide them into smaller subblocks. Each subblock organizes the garbage collection and the drinking water availability for its own use whereas the rainwater is collected in each unit and used for domestic use only (graywater). Every subblock with a boundary along the river edge is responsible to clean this graywater and then drain it into the river.
The sub-block sits between a private unit and a communal block, fulfilling many of the inhabitants infrastructural needs internally. Minimal interventions on the ground floor preserve the walls as space defining elements, resulting in both a continuity of the social structure and a solid base for the physical intervention. Due to the very random arrangement of these concrete and brick walls, the vertical extension consists of a wooden frame construction, adapting to each specific structural situation. Each sub-block accommodates one new building with drinking water collection facilities, providing the other sub-block units with fresh water. Waste water is dealt with in a similar fashion, where one unit houses a purifying system, treating all sub-block waste water.
The block is at first provided with functioning roadsystems and bridges, that at the same time contain infrastructure. Raw water can flow along the canals to the river.The two blocks that we received have two very different situations. One Block is set at the steep river edge while the other one has a flat edge. Since the flat area is very low, there it’s flooded badly every year. We would like to propose to enlarge the river width and bank up the ground on the block. Since the Landscape is very flat it will be used as agricultural land. On the steep side, we propose a wide staircase to handle the strenght of the waterflow. The two different situations need different unit typologies.
