It is clear that working with historic structures is both more environmentally sustainable and cost effective than new architecture and construction—and many believe that the best design occurs at the intersection of old and new. Françoise Astorg Bollack presents 28 examples gathered in the United States and throughout Europe and the Middle East. Some are well known—Mass MOCA, Market Santa Caterina in Barcelona, Neues Museum in Berlin—and others are almost anonymous. But all demonstrate a unique and appropriate solution to the problem of adapting historic structures to contemporary uses. This survey of contemporary additions to older buildings is an essential addition to the architectural literature.

“I have always loved old buildings. An old building is not an obstacle but instead a foundation for continued action. Designing with them is an exhilarating enterprise; adding to them, grafting, inserting, knitting new pieces into the existing built fabric is endlessly stimulating.” —Françoise Astorg Bollack
