Book excerpt: A brief introduction to the construction and history of basic shelters. Shelter is one of our most basic needs, and throughout history mankind has been highly inventive in meeting it. Simple Shelters introduces the principal types of wooden and stick-frame structures built around the world, examining how their shape and form reflect cultural and cosmological considerations as well as climatic and utilitarian needs. Charting the gradual shift from the circular homes of the nomads to the rectangular ones favored by settled people, Jonathan Horning explores materials and construction principles over millennia, including the geodesic experiments of the twentieth century.
