市庁舎内部：ロビー、議事堂、構造階層

Design a civic government interior inspired by the Tokyo Metropolitan Government Building. Organize grand entrance halls, public service areas, assembly chambers, office floors, sky lobbies, and observation spaces around a clear structural hierarchy. Use natural stone, exposed structural elements, aluminum detailing, and controlled daylight to express institutional clarity and civic dignity. A vast granite-floored entrance hall with massive square structural piers clad in dark stone rising through the full height, a modular grid of aluminium panels on the walls reading as a circuit pattern, citizens crossing to service counters, a glazed roof far above, cool controlled daylight, wide one-point perspective, 24mm lens, interior photography, ultra photorealistic, 8K
