As Harvard faces a period of great physical growth and change, it is particularly important for its planners and designers to work from a strong basis of understanding of the varied patterns that make up the University’s existing fabric. This report comprises an initial effort by Harvard Planning and Real Estate (HPRE) to document and analyze those patterns. It is intended as a working document for the many members of the University community who share responsibility for decisions concerning the future of the unique and rich physical setting that is the Harvard campus.
