Greetings from your southern neighbour.
This:
looks really cool
As for the Professional building, I'm on the board of a heritage preservation group down here, and my personal mantra is to preserve what's beautiful, and save what's ugly, but get rid of what's boring. By ugly I mean things that were designed to look that way, tastes change.
That said, the new design also looks great, but I'm guessing the era of the original style has a lot less examples in town than the all glass clad replacement.
