In this study, we investigated changes in quantity and function of open spaces before and after housing complex reconstruction in the areas of Senri New Town where there were concentrations of rebuilt housing complexes, and sought out the challenges in open space renovation accompanying housing complex rehabilitation. The results revealed that, in the areas where suppliers of rebuilt housing complexes changed from the public sector to the private sector, both the total area of green spaces and the ratio of green coverage were the same as before the reconstruction of housing complexes. The area of greenery on natural ground and the ratio of tree coverage decreased, while those on artificial ground increased. In the areas where the public sector rebuilt housing complexes, the openness of open spaces remained intact, but their availability declined because of the drastic decrease in green area and the subdivision of open squares after the reconstruction.
