So the building is 121 years old and it makes me wonder if it'd be better/cheaper to just raze it and build a replica/similar style in its place using modern materials with perhaps apartments or event space (better for the odd floor plates maybe?). This is a good thought experiment moment on the nature of landmark preservation. If the interiors and facades are gut renovated anyways, is it still really the same building? If you completely rebuilt it you could make a new building that'll last another 100 years instead of constantly repairing the current one.
