I would not hold my breath on any radical re-design there.
The new bar BeeHive will be ready shortly, I do not know that they plan on going to the plaza as Hamersley's does. Though I would not be surprised.
That the area around the Pine tree looked barren in January does not surprise me. I can't wait for the "urban Easter Island" sculptures to come down...Did I say that out loud? Uh oh!
I saw that show last year...Um...Didn't see a lot of choices really. Seemed to be more of an exercise for those competing. Little was considered for the existing uses/needs. The competition included far more than just the Plaza. Some had no, or little concern for the historical nature and just seemed an attempt to future-ify the existing buildings.
The BCA holds the building from the Calderwood, to the Hamersley corner.
An interesting note is that Buckminster Fuller's grid which hangs inside the Cyclorama was recently re-rigged. Much better now.
Also, the Cyclorama needs room out front, for loading in of shows. They have a loading dock out back, but the right to use it regularly was lost when the corner was developed. A concession to the neighborhood, that there be only one loading zone on the street.
