Those renderings are awesome, but they belong more in the area around Station Square than Southside Works, at least in my opinion. Those renderings would look completely out of place with respect to the current buildings both in Southside works as well as the rest of the South Side in general. I definitely would have liked to see a more interesting hotel pop up instead of that pretty dull one that's being constructed now, but something with so much glass like the most recent rendering posted would just be extremely out of place there. Perhaps something like the original rendering (photo three) could have worked well, not sure...
Honestly, I see taller buildings (10-20 story range) around Station Square, especially with the incredible downtown views that are present there. While the views of the river and the science/industrial buildings on the opposite side of the river are nice, the buildings of Pitt/CMU/Oakland in general are cool, the views just don't compare to the ones across from downtown.
Ah well, every city has had proposals like these, and the vast majority of them end up in the shredder...
