The building instinct as it is evidenced in domestic, religious, commercial and public architecture, from the primitive to the present, the world over. A comprehensive, intelligent, careful, readable study of architecture's ideals and styles in its reflection of the people's problems, experiences and development. The contributions of the various eras, the discoveries and inventions that changed building, the people who have left their mark examples of points under discussion, the mastery of materials and elements -- a solid, interesting piece of work.
