In our last house, we had a 17x24 unfinished office/workshop; however it was still uninsulated (and in North Carolina), so I "temporarily" set up my reloading in a VERY small walk-in closet. I built a bench out of steel, with ¼" plate top surface, legs out of forklift overhead guard material (3/16" wall 2x3 rectangular tubing), and plenty of gusseting. The top surface is only ~20" x 30", but it weighs 130 lbs. I originally set it up with the 30" face bolted to the wall, and a single Dillon SDB (swapped it out with another complete SDB when loading large primer calibers). We ended up moving before I ever got the workshop insulated.
Fast forward to our current house (5 bedrooms plus 2 family rooms and den), and I ended up in another small walk-in closet! It's the "under the stairway" closet, and it was the only place where I could anchor to a wall which did not border one of the bedrooms. At least I have the space to have both SDB's in place (I anchored the 20" face of the bench to the wall). I've figured out (by experimentation) that I can get away with the noise if my wife is already asleep, but it's still too noisy to load if she's just going to bed. Our toddler could care less, as her bedroom is 40' away. I've got a nice set of built-in benches in my workshop behind my garage (unheated), and I may pre-drill for mounting the press in case I ever need to do some late-night reloading (like when I sign up for a 600-round class at the last minute).
