I rode past this building yesterday, at Michigan Avenue and 35th Street, and noticed a lot of work being done to it.

Google Maps shows that at one time, all of the windows were closed with cinder block. That is now being removed. It also reads Bargain Office Equipment in the Google photo.

The Michigan side of the building has "555" on it, like 555 Gallery. There are a few other buildings around town that are branded 555.

Any idea what's going on?

By the way, sorry about the crappy cell phone sunset photos.
