Tower on a Historic Base

Design a sustainable high-rise that transforms an existing historic building into the podium of a modern office tower. Preserve the original architectural character while integrating advanced environmental engineering, transparent facades, and efficient structural systems. A carved stone historic facade retained in full with a faceted glass and steel tower rising from within it, the join expressed as a clear recessed gap, the old stone untouched and uncleaned, contemporary diagrid above, clear daylight, low viewpoint, 24mm lens, ultra photorealistic, 8K
