In this book, Thiis-Evensen develops a grammar linked to the basic elements in the art of floor, wall, and roof. Focusing on examples from architectural history, he discusses specific archetypes as themes over which the basic elements vary, and explores how these archetypes affect
us psychologically. In addition, the author shows how schematic postwar architecture can be replaced without copying motifs from the past, and allows us to better understand architecture's emotional aspects.
