The first building is essentially finished. Hermes, Festari for Men, New Balance, and RDG/Bar Annie have moved in, and I believe one other retail tenant whose name escapes me at the moment.
I was the one who took those pictures last week when I took my family to Discovery Green and I have no idea what those objects are. I took those pictures over the construction fence, so I did not see those items until I reviewed the pictures later. The next time I go down there I will try to see if I can talk to a worker about what those objects are. I go downtown twice a month and send my pictures to the skyscraperpage forum, so be on the lookout for more info there and here. My screen name is johnme there as well.
Well, if it is Gensler designing the building we are pretty much guaranteed another glass box. Unfortunately, I haven't seen much that they have designed that is very creative. I would love to be wrong.
