绿屋顶候车亭：一块被抬起来的草地

Design a bus shelter whose roof is a piece of living meadow lifted off the ground. Show a simple flat structure with a deep planted roof — 200 millimetres of substrate visible as a distinct band at the roof edge — supporting a dense mix of sedums, wild grasses and small flowering perennials growing thickly and slightly unevenly, some stems leaning over the edge. Detail the roof edge as a simple slim metal upstand with a visible gravel margin, honest about the construction. Show the supporting structure as minimal — four slim columns and a plain soffit in a pale timber — so the green mass appears to hover. Detail the seasonal state honestly: some plants in flower, some seed heads gone brown, a few gaps in the planting where establishment has been patchy. Show bees and a butterfly in the planting. Set it on an urban street where it is the only green thing in the frame, contrasting with asphalt, parked cars and a grey building behind. Show summer morning light. Photorealistic, green above grey, eye-level three-quarter view from slightly below.
