This is planned for the site of what's now the old Courthouse overlooking Centennial Plaza - which is a fairly small but nice, if not underutilized, public space. The city voted to purchase the old building this morning. It's across catty corner to the Bank of America Tower, the current tallest in town and across the street from a twin-towered Doubletree Hotel.
This report (w/video)
has a few more renderings visible. Also of note, it says the building will have "Class-A" office space & "a state of the art five star hotel".
That alone tells me it will either -a- never come to fruition or -b- there will be a final version that is greatly scaled down. Given the fact that there is still an issue with vacancy in many of the buildings downtown and that the only new construction of any kind in that part of the city deals with rehab of existing smaller structures that had, themselves, been vacant for some time and a few other, older midrises have been demolished within a few blocks in recent years... yeah. Not so optimistic on this one.
