My company has last week switched to an Activity Based Workplace. Meaning; no solitary offices, huge open spaces, no assigned desks, and the cubicles aren't even cubicles (the dividers are waist-level...).

As a big introvert, I can't focus like this. I need "tethering" in the form of having my own desk to return to every day, and I need a distraction-less environment (music in headphones only do so much - I still have people in my visual periphery at all times, as well as people walking up to me at any time during the day). My actual time spent working now is maybe 2-3 hours out of my 8 hour day. Which is insane.

How can I best address my need to have a "static" space that I can call my own in an environment like this?
