漂浮的曲面屋顶：悬浮于老城之上

Design an intervention in a historic low-rise district in the manner of Ma Yansong, inserting a mirror-polished stainless steel volume that hovers above the existing grey brick courtyard houses and reflects them, adding floor area without erasing the fabric. Compose a small bubble-like stainless addition sitting on an old tiled roof, its curved surface returning a distorted image of the courtyard, tiled roofs and a persimmon tree, the original grey brick untouched beneath, warm low afternoon light glinting on the metal, eye-level view from the lane, 35mm lens, architectural photography, ultra photorealistic, 8K
