In this book, the many factors necessary to make city spaces more child-sensitive are considered. Particular attention is given to dwellings and play spaces. Child development as it relates to the spatial environment and the child's use of various spaces (houses, apartments, service areas, playgrounds) at different ages are investigated. The importance of the spatial environment in spontaneous learning experiences, social interactions and transmission of values is discussed. In Part I, many aspects of child development from preschool through middle childhood are examined, including physical growth, activities, personal and social development, and intellectual and perceptual development. The relevant design implications are outlined. In Part II, child use of the physical environment is explained with reference to private, public, personal and group spaces. Suggestions are made for planning child spaces. In Part III, design guidelines for planning child environments are set forth. Numerous photographs and diagrams, as well as charts and tables, illustrate design problems and possible solutions. Safety considerations are stressed. Most information presented in the book is based on a report entitled "Children in the Residential Setting: A Discussion Paper Toward Design Guidelines," prepared for the Central Mortgage and Housing Corporation, Ottawa, Canada.
