Unbuilding by David Macaulay
This fictional account of the dismantling and removal of the Empire State Building describes the structure of a skyscraper and explains how such an edifice would be demolished.
"It is not a work of nonfiction but a work of fantasy, and not the story of the making of the skyscraper but the story of the unmaking of a very particular one, the Empire State Building . . . The exquisite drawing style that marked Mr. Macaulay's earlier works on architecture remains as whimsical as ever." - The New York Times
