Memorial Hall of Folded Concrete Slabs: A Brutalist Pleated Facade

Design a memorial auditorium in the manner of Balkrishna Doshi's Tagore Memorial Hall — a raw concrete mass of deeply folded angular planes that read as a single sculptural block, the folds doing the work of structure, acoustics and shading at once. Compose sharply pleated grey concrete walls rising to an irregular parapet, deep shadow in every fold, a broad flight of steps to a recessed entrance, no window on the main elevation, dusty ground and neem trees, hard Indian sun raking across the folds, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
