Steel structure apartments and wooden apartment buildings were indispensable in people's lives as the first step of "property ladder" after the rapid economic growth in the mid 50's. However, many have become obsolete today and remain abandoned in the urban areas due to the excessive supply of newly built apartments. This project is unique in the sense that, under the concept of "Nariwai x Living," it offers a multi-family unit that combines housing and workplace to revitalize the community as well as the residents' lives. Only adding minor changes to the building itself, it allows the residents to modify their apartments through DIY, a factor that ended up contributing to the popularity. By utilizing strategic marketing and not going overboard with the design, it has successfully accomplished to connect the memories in the community and show a path to solving today's issue of vacant houses.
