MOVE!
JK. ..... I had that problem a short time ago as well. I actually had dedicated our spare bedroom to my modeling illness, but then we moved our teenage niece in with us so ............ Plan 2
I didn't think I could squeeze any more into our living room, but, even with my surround sound system not allowing the room to be re-arranged, I managed to place a small old, antique desk in there, stuffed the drawers with my modeling crap, and am very happy there. I'm not hiding from the wife and can keep up with the everyday stuff while enjoying my hobby/disease. It might help to keep some potentially dangerous looking items on the desk as a deterrent to curious hands.
