Playground on Post-War Vacant Lot: Abstract Steel Frame and Circular Sandbox

Design a small city playground in the manner of Aldo van Eyck on a leftover bomb site, furnished only with abstract geometric equipment: a domed climbing frame of thin steel rods, a low circular concrete sandpit and three cylindrical stepping blocks of different heights. Compose the pieces placed asymmetrically on plain paving, no colour and no representational shapes, brick party walls of surrounding houses rising behind, bare trees, cool flat Dutch daylight, low eye-level view across the equipment, 28mm lens, landscape architecture photography, ultra photorealistic, 8K
