Create a black-and-white 2D top-down structural floor plan of an indoor police station detective team shared office, frame only. Draw one enclosed open-plan office shell with four thick black boundary walls, labeled only “Detective Team Shared Office,” with no furniture, equipment, desks, monitors, objects, or fixture symbols. Show a main door opening on the wall facing the internal police corridor/common area, with a clear swing arc and unobstructed access path into and out of the office. Show a separate internal passage opening on another internal wall leading toward the meeting/common work area, wide enough to indicate multiple people exiting, but draw only the opening and connection direction, not the adjoining room interior. Place modest exterior window openings only on the exterior wall of the office, clearly cut into the outer wall line, with no windows on internal partitions. Keep the plan pure monochrome linework: thick black walls, white openings/gaps, minimal functional labels, no color, texture, shadows, perspective, people, or movable items.
