An Architect's Address Book is memoir in 18 chapters of the places Robert Lemon has lived, studied, and worked over the past six decades. Some are of places that he has visited many times and are important to his career.

Studying architecture and conservation, Lemon has lived in Ottawa, Paris, London, Rome, and York. His work has involved projects in Vancouver, Los Angeles, Dorset, the High Arctic, and Xi'an. Other stories are about visiting the buildings of Andrea Palladio and Carlo Scarpa in the Veneto, Arne Jacobsen and Kay Fisker in Denmark, and five iconic 20th-century houses in France, in company of colleagues.

Most of the chapters focus on someone influential to Lemon's career; and his vast interest in food is a thread through most stories.
