We have a bedroom in our basement that we used to call the office, but now I think my wife refers to it as the junk room. Since my brother in law started managing a donation shop, we have been moving a lot of our unused stuff to him for that. It works out well for us and things are a little bit cleaner. Good luck with the work today!
My office/den looks like a junk room right now because of work being done in it, but should be ship shape within a week or two. That is pretty convenient that your bro-in-law has a shop to take some stuff. We have a thrift store down the road to take stuff to. Junk is the limitation. We have to fit it in our city trash can. So it has to be spread out and if large, broken in pieces. My biggest problem has been my health. Now that I am feeling better, it all just seems overwhelming to make it all square again.
I think most all of us have a room like that probably. My wife thinks the garage is messy too, but honestly I think it isn't very bad.
