3D Model: A Monumental Brutalist Concrete Building, Formed By Massive Cubic And Rectangular Blocks Intersecting Each Other. Sharp Geometric Lines, Raw Exposed Concrete With Subtle Weathering. Some Blocks Cantilever Outward, Creating Dramatic Shadows. Minimal Windows: A Few Narrow Slits And Square Voids. Main Entrance Is A Large Hollow Framed By Thick Vertical Columns And Horizontal Beams. Surrounding Plaza Is Flat Concrete Tiles In A Grid. Bright Daylight With Clear Blue Sky, Producing Strong Contrast Between Light And Shadow. Atmosphere Is Austere, Futuristic Yet Timeless, Resembling A Dystopian Civic Landmark Or Fortress Of Knowledge.
