My work location has been moved to another building so that I could be closer to my boss and he could supervise me more easily. I have been instructed to move my computer and work related materials there.
I have been at my current work location for over a year. If I move suddenly without telling anything to my office-mates, they would likely speculate as to why I moved or have questions. My office-mates may also be indirectly the reason for my move. There was a period of time when I took my lunch hour at a different time than them, or came in a bit later than them, leading to them speculating why I was not in office. This likely bubbled up to HR, who asked me to move via my boss.
I am concerned that if I just pick up my things and move without any notice, it may negatively affect things. At least two of my work-customers expect me in my current location. My boss and HR are aware of the move, so I am not concerned about them. However, I am concerned more about my floor neighbors, who typically come to me for various tasks or questions. If I disappear silently, there will surely be questions like, "Where did he go?", "Why did he move?", "Was he fired?", etc.
How do I best handle this? Do I say "I'm moving" to everyone or only to people I have been working with closely? My goal is to not create a bigger rumor mill, and execute the move smoothly.
