This (from the previous page on this thread) gives a pretty good sense of scale (at least on an order of magnitude basis) and a fairly cogent approach to site planning (setting aside more specificity with respect to details like grade activation, urban design, mix of uses in each tower, and whether any part of any of the extant structures would be kept).
Can we have this tower reach over 350 hundred meters please ! It would create a more jagged height look in the waterfront skyline ! As you can see the office towers at 250 metres range has that limit height look . As you can see in Koops diagram below !
