The two main problems of the kampung is the rapid growth of population and the missing infrastructure to live in a safe and stable environment. Our idea is to give the people an infrastucture core upon which the people have the potential to grow and build. Like the stem of a tree and its branches providing shelter. While growing vertically the footprint of the building becomes smaller and allows space for nature and recreation. The proposed vertical infrastructure gives the people the opportunity to deal with the different flood levels of the Ciliwung river.
