Another distinguishing element in the Yale core program has been the Yale Building Project, a first-year studio and summer program. Particularly under Dean Charles W. Moore, first-year students were pushed to design small buildings that ameliorated the life of poor or disadvantaged Americans, working as VISTA volunteers in the Appalachia. In later years the program focused more on New Haven and Southern Connecticut. A recent book on the subject documents the extraordinary breadth and significance of the work produced by students, many of whom went on to become renowned architects and educators.
