In this study, "renovation that generates a network of people, things, and events" is called Co-Renovation. The effectiveness of Co-Renovation is summarized in two ways. The first is that the openness of the renovation and the house will activate the connection between the people connected through the renovation. The second is that the renovation network will inspire an awareness of community development, and what started out as renovation-related connections will derive into autonomous regional activities. In order to increase the effectiveness of Co-Renovation, it is important to encourage the formation of spontaneous connections, and the factors that contribute to this are summarized.
