1. Note: This building height is incorrectly listed as 62m in both planning applications and in Emporis, but that is the height of the lower roof/arm of building (easy mistake from side elevation) but ignores the last 3 floors, to the upper roof (not a plant), real height is seen in plan documents already cited.
2. Recent applications, including the corporation street apartments and queens quay masterplan (see below with citations) have height as 57m not 62m assuming similar error with critical care building, by taking height above sea level as full height (cited in table).
3. New children's hospital application reveals original height was only above sea level not base to roof so 63m is height above sea level
4. Height above sea level once again being quoted as height (56m) but base to top it is 52m
