My workshop is rather scattered.
Like nerdnic and so many others the dining room table is my primary work surface. Though thankfully I don't have to clear it off when I'm done. I did for awhile...but it just collected junk that I then had to clear away to be able to work. Leaving my gear setup at least the table doesn't accumulate junk anymore
But it's a tiny dining room and a small table. So for working with 20x30 sheets of foamboard I have to take over the kitchen counter. Which means a lot of cleaning to make room since all the junk that no longer collects on the dining room table now tends to collect on the kitchen counter
And means I have to finish what I'm doing and clean my stuff off before the next meal...or pay for us to eat out. Honestly this is the #1 reason I haven't been building many planes lately. Mini multirotors fit a lot easier on my dining room table
But my actual workspace extends further. My back room is where my planes and multis are stored, and where my main computer is as well as boxes of parts.
But wait, there's more! My main "workshop" is actually outside. I have a freestanding 10'x10' office in our backyard from when I worked from home - now it's mostly hobby storage but I'm hoping to get it cleaned up this winter. My table saw, band saw, jointer and other large tools are stored outside under the shade over our outside kitchen (nice thing about living in AZ...can't use it all much in the summer but it stays dry!) my hand tools are stored in our RV but some live in my office and others live in one of my two sheds.
I guess that other than the bedrooms just about my entire house/property serves as some part of my "workshop"
Thankfully my wife is very supportive and enjoys most of my projects!
