The topic of how new and old buildings are to be related to one another is one of the least-discussed and most widely mis-understood within the profession of architecture. This book, and another like it, the earlier "Architecture in context: Fitting new buildings with old" by Brent Brolin, are two of the few good books I've found that tackle this issue, and each features essentially case analysis of both successful and unsuccessful examples of the relationship between new and old buildings in many different forms. In fact, the two books have very little, if any, overlap in content, and therefore make very good companion books. These are must-reads for any architecture, urban design, and historic preservation students (and practitioners) involved in this type of design work.
