"Design a modern 6-story building with a sleek, geometric structure, inspired by contemporary architecture. The building should have clean, sharp lines with a minimalist aesthetic. The rooftop features a flat design with additional elements to break the monotony, including a small rooftop garden with green plants and trees. On the top floor, include slightly larger balconies with glass railings to add visual interest. Use contrasting materials like concrete, glass, and wood, particularly in the upper sections, to enhance texture and variation. The facade should feature horizontal lines and large windows, creating a modern, elegant appearance. Ensure that the skyline is distinct but not overly complex, maintaining a refined, clean look under a clear blue sky. The building should blend into an urban environment while standing out due to its architectural simplicity and green rooftop."
