白色体块与草坡：融入地形的市民建筑

Design a civic building in the manner of Alvar Aalto set into a gentle slope, where a grass-covered stepped landscape rises to meet a white marble-clad volume and the roof of the lower wing becomes a public lawn. Compose a low white building with a fan-shaped auditorium volume, Carrara marble cladding on battens, a grass amphitheatre cut into the slope in front, mature birch and rowan around the edges, a still black-bottomed pool at the base, soft grey Nordic light, elevated wide view, 24mm lens, architectural photography, ultra photorealistic, 8K
