Exposed Concrete Beam Ends: A Library That Can Continue to Grow

Design a public library in the manner of Arata Isozaki's Ōita Prefectural Library — massive square-section concrete beams left projecting unfinished from the ends of the building, deliberately expressing that the structure was designed to be extended later like a growing organism. Compose heavy board-marked concrete beams cantilevering into open air with exposed cut ends, a stack of horizontal volumes beneath, deep recessed glazing in shadow, a bare paved forecourt, no cladding or trim anywhere, hard sunlight on the raw concrete, low three-quarter view at the beam ends, 24mm lens, architectural photography, ultra photorealistic, 8K
