Was this the Lotus building in Cambridge, MA? IBM had an "innovation center" on one of the floors (I think 7 or 9) that I used to work in when I worked for IBM in 2001. The Cambridge Side Galleria was close by. I stayed in the Royal Sonesta hotel that was attached to that building.
No, but it was nearby. I forget the name of the building but it was right across from the mall, near Hoshmand's I think. It was taller, brick, and had a big atrium.
It was the Davenport Building, http://www.thedavenportcambridge.com/. This was originally the home of the furniture company that manufactured Davenport sofas.
