One of the characteristics of the growth of Jakarta's metropolitan city is the emergence of large-scale planned settlements outside the city that previously had the character of rural areas. Although physically there is a spatial separation between the indigenous settlements and largescale planned settlement designed by developers very firmly, but the indigenous settlements still exist today, and they can integrated with the planned settlement. The purpose of this study is to find out how residents of indigenous settlements can survive in the face of changes with the pressure of the emergence of large-scale planned settlement vicinity. The research uses a case study method, with observation units covering one indigenous settlement, while the analysis unit takes the form of social interaction based on economic activities both routinely and incidentally. The results of this research showed that there are formed integration between indigeneous settlement and new town was greatly influenced by the emergence of opportunities to obtain additional family income through changes in space in their houses that were used as business houses and rented houses. The changes in the function of the building gave rise to socioeconomic characters because the residents still maintained the values of closeness even with migrants. This condition produces a spatial character called socio-economic spatial formation, and supported by aspects of access that continue to connect between the two settlements.
