The buildings of Frank Lloyd Wright are not immune to the social and environmental forces that affect all architecture. Because of the popular recognition and historical significance of his work, however, the stakes are unusually high when his buildings are modified in any way. Any additions or changes must meet the highest standards; how exactly this can be achieved is the debate that fuels this compelling new book. The essays collected here are authored by many of the top professionals in the fields of architecture and preservation. Some of the contributors worked directly on the buildings discussed and provide invaluable firsthand accounts of these projects. This is the most thorough discussion of modifying Wright's works published to date and a fascinating commentary on preserving our architectural legacy.
