I wish we had more renderings of this thing. I tried looking online but turned up nothing. Maki doesn't have it listed on his website.
I think this has the potential to be a real gem of a building. A sort of jewel box for the Cooper Union area - much more subdued than either Mayne's new academic building or Gwathmey's Sculpture for Living. I see a direct reference in the design to the Black Cube, which makes this instantly contextual.
Still, it looks deceptively small in that rendering for a nearly half million square foot building. Need to see alternate views.
