I take direct issue with "good offices are wide open spaces," a statement that is strictly opinion in its most charitable interpretation, and actively goes against scientific research on productivity.
I don't mean open offices. They're even more crowded than cubicles. I mean the classic ones where you have walls, a door, your own desk, a few feet from your desk to your door, a bunch of bookshelves, a few monitors, a window, and nobody enters your office unless it's important.
