Elevated Civic Architecture: Brutalist Concrete Columns and Void Floors

Design a civic library in the manner of Kiyonori Kikutake with its whole main floor raised on massive board-marked concrete piers, leaving a full-height open undercroft at street level as covered public ground. Compose the heavy slab edge running unbroken above, deep shadow under the piers, a broad external stair climbing to the entrance, exposed concrete showing plank grain and tie holes, an empty paved forecourt, flat overcast light, low view into the undercroft, 24mm lens, architectural photography, ultra photorealistic, 8K
