People here talk a lot about being able to have closing doors. My experience with private offices was, barring confidential conversations or rarely going really heads down for a few hours, the unwritten policy was you kept your door open. I've never worked anyplace where private offices generally had their doors shut.
Agreed, but having a door meant you could put the "do not disturb" sign up. Of course that's pretty specific to your companies culture, but if someone closed their door at my office, I'd stroll around later.
One of the biggest benefits of course is that you have a lot less sound travel. Doors open and you'll still be able to have a neighbor that has an open door meeting, phone call, etc and it won't interrupt you.
After moving from a private office with a door to a team space, I missed it severely. Now I'm WFH and when my kids aren't home generally my door stays open.
I don't have a large sample size but across multiple companies in both New Orleans and New England, closed doors sort of meant: "I have a specific reason not to be disturbed." Which didn't include I just prefer to be in "flow" or whatever. The situation is probably different if you're on a busy public corridor as can be the case in universities, etc.
