Unless you're in a position where you absolutely need a certain expert (such as a research project) or a few other special circumstances (if its quit or go remote situation, say someone moving for non-job related reasons).
First off, that whole 15 minutes thing is absolute bullshit. Maybe its a worst case if you were in truly deep thought over one of the hardest problems of the year. But most of the time you aren't, and it will be a few minutes Like around 1.
Secondly- your productivity doesn't matter. The team's does. Those interruptions- it means a team member needs help. They're blocked. Their productivity is at or near 0 until unblocked. If interrupting you costs 15 minutes from you but saves an hour for him, that interruption is worth it for the team. There are almost 0 of those interruptions that aren't a net gain. Now if you have a problem with particular people being too disruptive, that's a management/personnel issue you should bring up to your manager.
Thirdly- not everyone works well in remote situations. Especially not long term (working remote for a day while you wait for a package/your maid/etc is a different matter). Very few people actually end up working as well as they do in an office- there are MORE distractions at home. And communications do not work as well- video conferences do not work as well as talking to someone in person. Even if you're one of those who do work well from home, you won't be as efficient as you would sitting near the rest of the team.
