- Wikipedia: 271.3m (project DA figure; Crown marketing rounds to 275m)
- highest_occupied_floor_m
- Wikipedia: level-66 free public observation deck anchored at 250m; Crown sky villas occupy floors 67-69 (~259m); levels 70-71 mechanical/utilities. Top sky villa at floor 69 used as highest occupied. Free observatory at level 66 exists but is small and not a primary public attraction (no TBC deck profile).
