I've been WFH since Covid and, when it first happened, my office was in a finished attic that was not well conditioned. I like it warmer so I didn't mind, and the lack of comfort for others meant I enjoyed more solo time.

These days, I may as well not even have a door. I put auto-shutting hinges on it, but that failed as reminder/deterrent long ago.

We've got a 10x20 out back that was supposed to be my workshop, but it's filled with all the things most Americans put in their garages - because we don't have one. I'm seriously considering a deep purge and converting at least 1/2 of to an office; the distractions and context switching are disastrous.
