河岸市民地标：木结构与动态外壳

Design a riverfront civic landmark inspired by Shigeru Ban. Combine cultural venues, public libraries, event spaces, innovation centers, observation decks, cafés, and riverside parks into a timber-based environmental architecture emphasizing renewable energy, dynamic envelopes, and civic openness. A stepped timber-framed volume facing a river park, a movable louvre envelope partly open along the south face, observation decks cantilevering over the water, cross-laminated timber visible throughout, warm evening light with the interior glowing between louvres, three-quarter view from the riverside path, 28mm lens, architectural photography, ultra photorealistic, 8K
