Second revised and expanded edition.Until the 1980s--and in rare cases until today--playgrounds were places for social experiments, risky projects, and spectacular sculptures. Architects, urban planners, artists, parents, and children were invited to leave their comfort zone and to venture into something new. The Playground Project brings many of these exemplary, but nowadays forgotten initiatives, pioneering designs, and adventures back.Examples from Europe, America, Japan, and India are discussed in depth and illustrated with numerous images. This is the first comprehensive overview of this kind, and addresses laymen as well as experts who want to do more than just seesaw and swing. It includes works by artists, architects, and landscape architects such as Marjory Allen, Joseph Brown, Riccardo Dalisi, Richard Dattner, Aldo van Eyck, M. Paul Friedberg, Group Ludic (Xavier de la Salle, Simon Koszel, David Roditi), Alfred Ledermann and Alfred Trachsel, Palle Nielsen, Egon Møller-Nielsen, Isamu Noguchi, Joseph Schagerl, Mitsuru Senda, and Carl Theodor Sørensen.This new and expanded edition, published on the occasion of The Playground Project exhibition at the Bundeskunsthalle in Bonn (13 July - 28 October 2018), includes a new chapter dedicated to playgrounds created in Germany, as well as new biographies dedicated to the KEKS collective and Cornelia Hahn Oberlander. Published with the Kunsthalle Zürich and with the Bundeskunsthalle Bonn.English and German text.
