I would prefer they not alter the facade design at all, but if they're still keeping the some of the integrity of the original design, then I'm all for it! I'm so happy they're not covering it in plain green glass like the original plan suggested.. Architecture from that era needs to be more respected, and in my opinion, this is an impressive building. It just needed a clean.
It'll be funny when one day we will be kicking ourselves for hating buildings like these, just as the architects from the 20s hated Victorian buildings, and architects from the 60s hated early century buildings.
