This. A big problem with office work is office cube design. I'm old enough to have had a closed door office in the 90s and it was the best. I also worked in large cubes which had moveable partitions as walls where you couldn't see your neighbours. They were also good, not great, but better than today's cubes. They even had large book shelves where you could keep your reference books!

At home, I can close my door and it is much superior for my personal productivity than an open office cube plan.

At least you get a cube or half cube. My office is basically a really long desk with 4 people on one side and 4 people on the other (directly across from each other), with maybe 5 feet between you and the next person.
