Material waste is an issue concerning both new and existing architecture. Located in Pristina, Kosovo, the proposal is a site specific material catalogue that will serve both as a method of site preservation as well as material re-use and circulation. The program is a cultural center that evolves with future generations of Kosovo. Through the process of borrowing and blending old and new materials from the site, a shared material library is created that allows for future generations to continually re-build to adapt to their evolving cultural needs and values.
