Our main idea was to separate the river from the green area and by doing so to create two different orientation sides that go along with different qualities of life, that allows a much more dense housing-typology. We intended to shorten the river flow and decrease the water speed during flood season with ‚green cuts’ through the mainland. These green canals would be carved into the ground – in this way they could accomodate initial water amounts of the flood and therefore would be unattractive for the inhabitants to built on. They would provide open space where nature can develop. Our housing typology provides a modular system, laid down on a grid organization, that is broken down to an individual, flexible unit. This Unit can be combined and adapted to different uses as needed and would be erected with prefabricated columns and beams – where walls could be filled up with brick.

Demjan Haller&Pascal Ryser_Midterm Review_Islands
In the most flood prone areas where building quality is the worst, there are islands created through canals. Those islands are used as town forests and restricted for people apart from the forestry workmen. On the opposite side of the canal there are eight storey courtyard buildings placed, which are of a mixed use of housing, shops and working space. The courtyard is one storey raised in order to get space for infrastructure (membrane filtration system, water tanks, garbage collection) and open working area for the workshops in the first storey which are on a flood proof level. The concrete structure provides infrastructural cores (stairs and wet walls) and slabs. Therefore the facade is nonstructural and can be constructed by the inhabitants.

The Hub Bukit Duri around the train station is connected to the Kampung with system of little ferries on the river. Different docking places along the Ciliwung transport people and goods whereas every second is only for goods especially garbage that is collected and recycled next to the station. Along the river there is a green belt that consists of public park strips or agricultural terraces that local people can use as productive gardens or farm fish in little ponds. The greenis interrupted by the docking places that also mark local centers of the housing blocks with a mosque and public space for recreation, markets and other community activities of the inhabitants can take place. The new river profile is widened in order to provide a higher water capacity during the flooding season. A narrower inner canal and a system of weirs allows the barges to operate also during dry periods and at places where the water would be too shallow.

Currently, the buildings with the poorest structures are located right at the river edge. We propose to replace these houses by new, structurally stable buildings which act as barriers in flood situations for the houses behind. On the sedimentation side, the houses are stepping back in order to widen the riverbed, while on the other side the units are placed right at the riveredge, preventing further erosion. With the integration of a green ribbon, which is leading through the whole Kampung we want to provide a continuing connection along the Ciliwung River. With its steps on different levels it can be used during different flood seasons. The center of the Kampung is dominated by a market garden with productive crops adjacent to a market where the cultured fruits, vegetables and other goods can be sold.
Our main aim in the kampung scale, was to find given qualities of the Ciliwung river and its various edge situations and to redesign them to deal with the flooding in a better way, but also to bring the life and the people to the river. Our Intervention area is only in the places where there is flooding. To free some space along the riveredges we needed to densify the the built structure. Our main densification area is set along the urban edge of the river, the steep edge, where people are the closest to the river. The flat riveredge fills up with water to create a flooding pond during rainy season. This land is used as agricultural land or as community gardens. We found that there were various riveredge situations. The steep edge needs fortification, wich can be provided by strong trees or by a staircase system supporting the ground. The flat side, that is mostly the lower side, needs more space between built structure and water. This is solved by using the flat river edge as agricultural land, or gardens. Another main intention was to connect the separated riversides by building bridges. To keep as much of the kampung life, we set them in places with are now used as river crossings. The bridges are connected by public buildings high enough to stand the river and to serve as landmarks for orientation. Along the whole river edge we intend to have a path.

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.
Bettina Dobler&Melanie Ziegler_Midterm Review_Junction of public life
Our interventions are located in the most flooded areas of the kampung melayu. we create new junctions next to the existing main roads which are connected across a large roofsystem. the new roofstructure allowes public life even during the flood season and gives the dense kampung a wide recreaction zone. The streets extend to an open space, wherever our new structure reaches the river front. Here the recreation zone from the roof landspace touches the ground. The riverbank in front of the public places are treated in a strong way. The hard river edge is stepped and generate different spaces with divers functions. Some areas at the river are more private with gardens just for the inhabitants. Here the river bank has a clear edge with the embankment. At some river side the housing zones move back more and give space for a forest garden, that reduce the influence of the flood and helps the river to regenerate.

Our goal is to improve the economic and personal well-being of the inhabitants in Kampung Melayu. We see the opportunity of the Ciliwung river being the driving force behind this improvement. The stepped riverside will include an agricultural belt with high growing productive trees and private gardens along the urban edge. The steps will provide a water retention area in case of flooding. The area of the old train depot will be reactivated as a market and craft hub for the whole Kampung. Our strategy for the built fabric is to create new sub blocks based on the structure of the existing building clusters, allowing an incremental implementation. One sub block is always gathered around a courtyard which is semipublic and gives the inhabitants a chance to have a private garden.

Mind The Step The interventions we propose in the first stage focus on the areas that are annually hit by heavy flood and need to be changed immediately. Like in our earlier proposals we keep the greenbelt along the river and the step system inside of the Kampung; the first big step seperates the green area from the urban area. We widen the river to average 25m and lower the riverbank so it becomes very sensitive to changes of the waterlevel and is safe of beeing build on. Inside of the Kampung the topographical changes due to the step system are conquered by ramps and stairs, which control the traffic and create new open spaces at the crossings of the ne street system; stepping down to the river only stairs are used to keep the riverbank free of vehicles.
In the midterm review, the teams presented the last evolution of their development, including ideas about the three scales of analysis (Unit, Block and Kampung). New visions of the river were presented with perspectives, in addition to sections and plans. An overall landscape plan of the Kampung developed by each team describes a complete reading of the site.
