I didn't show it, but there are over a dozen conference rooms, ranging from small (10x10 or similar size) to larger, 50-80 person rooms. You could schedule time in there to work if needed.

People also work flex schedules, so I'm sure you could work off hours to get some more separation.

I do agree that open environments can be hard, but they can be very collaborative. I think you want to get your culture right to match employees. If you got changed to or from an open environment, it might bother you. If you started in one, you might be OK.

as an aside, here's my current setup.
