Outline of Final Research Achievements

In this study, I focused on the role of user-driven renovation in creating a community and preventing the deterioration of vacant houses. I revealed that fostering the distribution and renovation of underutilized houses requires the understanding of the actual conditions of potential vacant houses and neglected properties, as well as the involvement of community organizations and intermediaries in facilitating the introduction of external individuals who appreciate the local community, such as immigrants. This approach can contribute to the revitalization of the community.
Additionally, considering the impact of the COVID-19 pandemic, I modified my research to reveal how the utilization of vacant rooms by the elderly group can promote the improvement of aged housing environments. Furthermore, I explored and proposed remote support technologies to enhance the quality of self-renovation by unskilled individuals for vacant houses.

Academic Significance and Societal Importance of the Research Achievements

団塊の世代をはじめとする居住者の高齢化が進み土地建物を次世代へ継承する時期を今後一斉に迎える住宅地が全国に存在するなかで、転出した子・孫世代が相続しても居住せず放置する住宅が増えることが予想され、今後空き家問題が急速に顕在化する可能性がある。こうした喫緊の課題に対して、本研究の成果は、様々な支援の活用促進効果を高め、空き家活用の考え方を事後対応から予防計画へと転換する新たなパラダイムを拓くものである。
