This book presents 22 preschool buildings from all over the world, selected on the basis of how well they approximate an ideal preschool where children and educators live harmoniously in exceptional settings. The projects also include technological innovations (experimental materials, specific construction details) and visible ecological installations, such as energy savings through the use of solar panels, tanks for rainwater collection, or recycling of materials. Each building description contains several color photographs. (An appendix discusses children's playgrounds.) (EV)
