Kampung Air is set in the city of Semarang in Indonesia. This city is facing enormous problems due to land subsidence. Kampung Melayu, which is the location of this project, has a rich history based on trade and commerce. However, now it is mostly abandoned and not functioning anymore. This project tries to deal with these problems by creating a new way of living with water. This project proposes to create new housing based around an aquaponic system. This is a system in which fish and vegetables are produced with the use of water. This system can help with water storage, create a new source of income and strengthen the social structure within the neighbourhood. The architecture of the building makes use of the climatic advantages the system provides, resulting for instance in the shape of the roof.
