It looked a lot like the offices from What Women Want with Mel Gibson and Helen Hunt.

the interiors are sets i guess.

The digicom interiors were a set, designed to match typical Seattle architecture. I would guess the mediation room was a set as well.

The exterior shots of Digicom are located in Pioneer Sq. On second thought, they could've filmed the interiors there too with false walls, making those behind the scenes shots look like a sound stage. They did something similar with the M Street house from The Exorcist. (Added a false front to make the real house look bigger.)

Awfully nice soundstage. However, someone elsewhere said there was a scene set in a landmark building in Seattle. I was trying to find out if that building was used in more than one scene. From the layout of the offices in the film with the sandblasted brick walls and huge expanses of glass; it looks pretty much like an old warehouse retrofit. Gorgeous nevertheless.
I intend to live forever. So far so good.

Pretty sure the office was a set. I remember seeing a behind the scenes segment on the movie back when it came out, and the office looked like a soundstage. Of course my memory could be faulty.
