Last fall, the Downtown Alliance unveiled a plan by ARO and a dozen or so other designers aimed at reviving an area the civic group dubbed Greenwich South. Among the proposals was an iconic, place-defining tower designed by one of our favorite firms, San Francisco’s IwamotoScott. While the Downtown Alliance’s plan was largely speculative, the tower has, uh, popped up once again, with bountiful new renderings on Inhabitat. It’s not entirely clear why the tower has been so thoroughly expanded upon, but we’re guessing all this new snazz has something to do with the firm’s upcoming appearance at the Design Triennial opening Friday, of which it’s a part. We’ve posted a few of our favorite renderings here, with more than a dozen available at Inhabitat.
