I much preferred working in the previous building, CS and AI lab building, NE43. It looked like a punch card from the outside, but had a very nice design with small offices (with closing doors) ringing a common space. The primary downside is the square footage per worker was decadent by today's standard.
Oh wait, we were talking about Frank Gehry, right? His museums looks cool but he should never have been allowed to design an office building.
