This paper clarifies the implementation of the core house concept in Indonesian housing developments from its inception until recently, and for its future implementation. The concept has been applied since the 1970s with several titles, but they share the same meaning of a house with minimum livable space which can be adjusted afterward incrementally by its occupants. It will still be an alternative for providing affordable shelter for lower income people in housing projects around the cities of less developed areas. As a self-provided incremental building process, the concept also needs to be promulgated to lower income communities since most of the housing demands are fulfilled by the community themselves.
