So, a few things. I don't hate the new design, though, it is less daring than the old one. I will say it's nice to see something that isn't strictly another glass tower, although, the old design likely would have had amazing reflections of the Frost Bank Tower to be seen from Congress, and now it won't. Still, I think it'll complement the Frost Bank Tower and especially the Austonian better than it would have with the old design, and it will add some texture to the skyline, which has been lacking that with so much glass.
This design reminds me of Two Union Square in Seattle, and that building has long been a favorite of mine.
The bad news is despite having more floors - going from 41 to 50, this will now be office and residential which will no doubt mean it'll be shorter than originally planned since office buildings tend to have higher floor to floor heights than any others do. So, even with more floors, it'll be shorter. A perfect example is The Republic - a 708 foot building with 46 floors of office space, but compare that to The Austonian with 10 more floors, but it's 25 feet shorter. And then there's 44 East that will be 51 floors, but only 573 feet. There's a chance this might not even hit 600 feet, though, that is a pretty significant crown, so I wouldn't rule it out completely.
I wonder if the design change had anything to do with Indeed Tower. To be honest about it, I think the two buildings would have been redundant and it would have diminished the design of both - and stolen Indeed Tower's thunder. I think this is a better outcome in that way. Even with this design, the two are similiar with their sloped crowns.
