The Devon Tower is now 48 floors tall. There are only 2 more floors to go till we get to the top.
The Rotunda has glass on the entire north side. They are still putting up the glass on the south side. Furthermore, the Data Center building has been connected to the north side parking garage. The Auditorium still has more work to do before they wrap up the outside construction.
It is neat that you will be able to get from any part of the Devon campus (auditorium, parking garage, tower, etc) without ever having to go outside. Each section is connected somehow, mostly with Sky Bridges.
