All of these are pros 
I’ve never been in a corporate environment, so my experience is all offices and office sharing in an academic environment.
I’ve always had an office, sometimes to myself, but frequently due to issues with space, sharing with one other person. I absolutely hated sharing an open plan office with ‘hot desks’ (which I had as a graduate TA and then in a couple of places where I was part-time faculty) for a number of reasons
- No privacy if you have a student with awkward issues (as well as nosy nancies who pipe up to interrupt a student-teacher conference either to add their two cents’ worth or to undermine something I’m saying – that never happened often, but it is absolutely infuriating when it does).
*Colleagues who cannot seem to grasp the idea of locking the goddamned door when they go home for the day/weekend. Twice I had to share a multi-instructor, hot-desk arrangement with the same person who did this consistently. No one ever left anything of value in this office because stuff did get nicked. This is a pain in the ass as it means you’ve got to haul sensitive documents and files back and forth every day because you don’t feel safe leaving them in the office
*Colleagues who think ‘open plan’ means they can help themselves to your books and reference materials
*hotdesking that means that even if you claim a desk, chances are good that you’ll come in to discover someone has swept all of you research/marking/set up for the next day’s lectures to one side so that they could ‘use your computer for a minute.’
*Colleagues who think open plan is licence to sit on the other side of the room and carry on a conversation with you when you’re trying to write a lecture, mark a paper, or just sneak in a few minutes on your own project. Or walk up behind you and scare the shit out of you because they’re silently waiting for you to notice them, so you can come fix their computer. Or who whistle, play the radio, talk loudly on the phone about stuff you really really didn’t want to know (I know way too much about a current colleague’s troublesome lady waterworks thanks to an open plan experiement from a couple of semesters ago).
*The Odd Couple syndrome: I myself like a tidy, organised office; I’ve shared with someone who was literally declared a fire hazard by health and safety because of the state of his office. I’ve also hated being housed in temporary offices (owner on sabbatical), and their office is an absolute rat’s nest. Having to pick my way from the door to the desk via a narrow goat trail aggravates the fuck out of me.
*Thermostat/open window wars.
I shared an office at my last adjunct gig with a FT full professor who was awesome, but I really prefer my own space. We’ve had issues at my current university in that we’ve been hiring staff faster than offices have been available, so people have been shuffled around into temporary offices based off who’s on sabbatical. Due to a series of retirements and transfers, though, I’m moving into my own, permanent solo office at the end of this month when they finished redecorating (renovating) them. Floor to ceiling bookshelves, my own giant desk, my own filing cabinet, and my own key.
Solo offices for the win; the admin wanted to put us in open plan offices and the entire social sciences faculty threw a collective shitfit. Nope, nope, nope. I keep my door open in the corridor if I’m at home to colleagues who need to converse or for students (and thank FUCK in this culture, students will come into your office ONLY if they have made an appointment; general office hours in the US sucked), or if it’s late in the afternoon and people are just faffing about.
But during the semester, colleagues will pretty much respectfully leave each other alone (checking first via email if one can come consult about an admin issue, etc); I don’t think any of us socialise outside of school hours except very very rarely because we’ve got long days and just want to go home to families or be alone at the end of it – semesters are pretty hectic and draining.
