A highly photorealistic architectural render in an industrial minimalist style: The space features smooth concrete surfaces in all walls, floor, and ceiling. Texture and color: The concrete has a light gray, uniform tone, with subtle realistic texture typical of cast concrete — fine pores, slight imperfections, but no visible seams or lines. Lighting: Soft, natural daylight from a large, indirect source, creating smooth, diffused shadows. No harsh reflections or direct sunlight beams. Surfaces are matte, not glossy. The finish must appear solid and raw, with a tactile, cement-like appearance. Composition and perspective: A straight, centered perspective showing perfectly aligned vertical and horizontal lines. No additional elements or decor: Only the raw concrete walls and floor are visible. No objects, windows, or external backgrounds. The scene tone is neutral to cool, avoiding warm or yellowish lighting, to preserve the industrial, minimalist aesthetic. Photorealism: High resolution, detailed texture mapping, subtle variation in shading across concrete surfaces, realistic lighting falloff, and soft, natural color gradients.
