"Design a professional architectural floor plan for an office layout. The plan should include individual director offices, manager offices, meeting rooms for 6 and 12 people, open collaboration areas, a laboratory, and a central lounge with casual seating. Near the entrance, place a well-organized sector with elevators, stairs, and bathrooms, ensuring clear circulation paths. The elevator zone should be central, with adjacent service spaces like utility rooms and access control areas. Maintain a modern, functional design with clearly labeled sections and detailed furniture placement."
