Playgrounds usually consist of pre-fabricated elements, which are A-Z tested and thousand times certified by various organizations; well that is the easiest (but not cheapest) way of doing it. Prof. Schmidt designed a landscape, without typical playground elements just with combining two materials / colors (tartan and grass) and with modification of terrain. Landscape as it is provokes children to play and jump around and up and down.
