In the most flood prone areas, a sequence of islands is formed. Close to those islands a new typology of Cluster Units is implemented. Split up into smaller units, the buildings fit into the existing subblock structures and mediate the newly introduced scale with the existing urban fabric. Along the river, a series of gardens provide a private type of green space. As soon as the water level rises, islands and gardens become part of a river that has  a cross-section of at least 30 metres. In flood case the courtyards of the Cluster Units stay dry. Underneath those raised courtyards, there are membrane filtering systems to provide drinking water. Through our project the Kampung becomes a system of islands and is provided with infrastructure and green spaces.

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.

home gardens for the public_The private space/garden in the Kampung is maintained and secured by it’s owners – this is why these spaces work much better than any public one where nobody feels responsible for its maintenance. At the same time we recognized that these private gardens have a positive influence on the public space and can also be temporarily used by the public. We therefore propose to implement a belt of Pekarangan Houses along the River and a Network of Pekarangan Houses over the whole Kampung.Those Houses work as a role model for further renovation of the Kampung and enhance the quality of residential and public spaces.Through this strategy of appealing the current residents by high quality housing typologies, we feel confident that the Pekarangan Houses will develop a healthy and vivid Campuran.

When visiting the Kampung we realized the importance of the street life for the people. The problem is that when the flooding comes, the people are disconnected from roadsystem and infrastructure – the river eats up the streets. Our vision ist to maintain streetlife, infrastructure and connectivity during flooding. We introduce a new typologie of concentrated infrastructural hubs. They are interconected by suspension bridges and are able to provide the qualities and functionality oft he dry season street.

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.

Central-Park _Through a shortcut in the course of the Ciliwung River, the yearly flooded area in the middle of the Kampung becomes a detention basin. The former inha- bitants of the generated island find a new home on the other side of the river. A gradual process of recultivation on the island can take place. A network of paths makes sure that the area can be used as a recreation zone – already at an early stage. After the restoration of the ground, the area serves for agricultural purposes and offers opportunities for fishing and recreation. The buildings form a clear facade to the park island. Through the decline of the building height and a network of overlapping roofs the rain water can be collected and will be stored on the highest point of the terrain.

Type 1:In Case of flooding, the workspace will be moved to the first floor. The violent flooding has taken apart the temporary constructions on the ground Floor. The units closest to the water come with deep point foundations, analog to constructions in the Netherlands. In a worst case scenario, at least the steel skelleton should survive the flooding.Type 2:To enable natural cross ventilation, the apartments reach from one facade to the other.. A reduced building structure meets the basic needs of the residents and can be extended horizontally and vertically. The compartmentation of rooms and the arrangement of the facade is left to the owner of the apartment. The participation of the residents leads to an identifying process.
