Population growth from year to year is increasing so that people need a place to live. Residents use the land beside the river to build houses. On the banks of the Krukut river, permanent wild houses were also built. One of the houses used as a case study has problems in terms of ecological architecture. This problem is seen in the aspects of design, function, and technology. The design problem can be seen from the messy shape of the house, the making of makeshift insulation from plywood, and the walls of rusty tin. Functional problems can be seen from the absence of green land in the area of the house that is used as greenery. All land is made of pavement. In addition, the function of the window as ventilation and natural lighting looks very minimal so that the house becomes dark and humid. The technological aspect is also not visible in the house, causing a negative impact on the surrounding environment. The purpose of this study is to humanize humans both in the house and around the house. The solution in the concept of ecological architecture is to design buildings that are good for humans as residents and relationships with the surrounding environment. It is important to note that the relationship between buildings, humans, and the surrounding environment runs harmoniously.
