Yes, I agree. We must (at this time) temper our expectations and celebrate that this building, if built, will be the first downtown office building constructed in a generation.
Take a look at
this...it is McKinney & Olive, a building currently U/C in Dallas (designed by PCP) and is one of the most talked about new buildings in town. Most love it.
However, McKinney & Olive is going to be 585,000 SF, 145,000 SF larger than a 440,000 SF Frost tower. Based on the 440,000 SF Frost proposal (and common office tower floor plate sizes of 15,000-20,000 SF), Frost should be between 20 and 30
levels of office. As already stated, it could be taller if a parking is located in its podium.
