The site is the construction site of the Tomei Expressway Gaikan JCT in Setagaya, Tokyo. During the construction of the expressway, large side-hole tomb ruins from the Nara period was excavated. The ruins were demolished as a “relict” that was troublesome to the construction, however there could be a way of saving the ruins from a demolishing as a “heritage” of the local neighborhood.
This Project proposes a “four phase development” of the site while maintaining the construction of the expressway at the same time conserving the ruins: 1. Excavation of the site → 2. Investigation of the ruins → 3. Construction of the expressway → 4. Conservation and restoration.
The building components will be repeatedly “repurposed” as the construction phase moves from one to another. Regardless of the “change” in the extrinsic form of each stage situation from the use of the same member, the function of preservation of the ruins will be continuously “maintained.” Since the ruins require  occasional restorations even after they are preserved, this architecture will be perpetually “updated.”
Thus, the preserved ruins give rise to “changes in things” and create a new base for local activities through the relationship between things and people, from change to maintenance, from maintenance to participation, through architecture.
