Situation: The two blocks are very different – one is defined by the old railway depot and the bridge becoming an important traffic axe affecting the whole block. The second block has a very common structure with a high density of housing and is bordered by the old railway depot, the Ciliwung River and a main street. Organisation strategy: In the common block we found a stripe structure defined by streets. We used these streets to incorporate a canal system flushing the sewage water of the houses into a buffering zone along the river. Further the stripes were divided in several sections having a water tank in each one collecting the rainwater from the roofs. The garbage collection should also be organised along the streets.
