老城陡坡的阶梯式插建：层层退缩的平台

Design a terraced intervention on a steep historic hillside street in the manner of Lina Bo Bardi, stepping small concrete platforms and stairs down between existing colonial facades so the slope becomes a sequence of public landings. Compose raw concrete treads meeting old rendered walls, a slender concrete column supporting one overhanging deck, tropical creepers taking over a retaining wall, the bay visible far below at the bottom of the street, warm late-afternoon light down the slope, view from the upper landing, 28mm lens, landscape architecture photography, ultra photorealistic, 8K
