The purpose of this research is to validate the adaptability of aged households to a housing project. The project for the elders is called "Sliver Reform" where the facilities of 2DK public housing are improved, while the original model remains unchanged. We analyzed the indoor lifestyle of 17 aged households before and after they moved to the renovated 2DK public housing. The findings are that 50% of the dwellers are highly-compatible with the housing improvements and they inherit their previous lifestyle, while the other half are found it difficult to adjust themselves to the improvements in the facilities. The reasons for the difficult adaptability are delineated as two: one is that some households found that the DK is too small even for a table, and the other is, due to illness, agedness and physical disabilities, some households mainly use the Japanese-style room with 6 Tatami mats on the southern side. The indoor lifestyle, including meals, of the former type of households has changed from what they had had; in the latter case, the multi-functional room and the Japanese-style room on the northern side become vacant or become a storeroom.
