New Renderings Reveal What Looks Like a 74th Floor Terrace at 1000M

Curbed Chicago had a post about some new renderings for the 1000 S. Michigan high-rise that's supposed to break ground in 2018:

As the yet-to-be-built 74-story South Loop skyscraper known as 1000M prepares to start marketing its 323 luxury condominiums, a pair of newly-provided renderings offer the best look yet at the upcoming Helmut Jahn-designed tower. The 832-foot building will feature greenish blue glass, metal horizontal spandrels between each floor, and a crown screened in metallic mesh.

While that's nice and all, we clicked over to their website and noticed a close-up of what we presume is either an amazingly high penthouse terrace or a crazy shared amenity outdoor rooftop space:

Pretty crazy to imagine a terrace on the 74th floor - might be a little windy up there.
