More than 1.100 khlong in Bangkok offer various opportunities for urban development. Over 2.200 km still exist in the Province of Bangkok alone. Transport and living space on the water are found only along certain parts of the system as khlong are predominantly used as open sewage, drainage and irrigation system. The particular urban structure creates complementary spaces that interface water with land. This article aims to understand the logic of structural elements of Bangkok in the Chao Phraya Delta of Thailand and to change the viewpoint, to look from the water to the city. To understand the research approach better the water space, consisting of the canal and the natural or planned fl ooded adjacent spaces, is disentangled and reconnected to the built landscape.
