The renderings have been pretty much slammed for it looking like a bloated Simpsons Tower. They are a couple of pages back in this thread, but of course you can always find them in the dataBase.
The landscaping incorporating and displaying the archeological remains is what's positive about this project. But to have this architecturally busy tower possibly ruining views of the Princes' Gates from the east is unacceptable. It looks like it will also loom over the waterfront, but it doesn't have the kind of iconic design to be able to stand alone. The city should at least have the interior volume redistributed. Looming over the Princes' Gates and the waterfront should be avoided. Also, in a city where heritage is often compromised without reflection as to whether such compromises are truly necessary, I wonder if all of the significant foundations are to be preserved, or just some, leaving people with an incomplete picture.
