Toshi, don't you DARE give up the hobby! First of all, I know Mrs. Toshi is very supportive of your hobby so, with her help, she'll make sure you keep on building.
Secondly, back when I was a kid and all the way up until I moved out of my parents' house, I used one of those "kid tables". You know...the little ones that are about 24" x 24" with the folding metal legs. I kept all my tools and supplies in a couple of fishing tackle boxes. Those, plus the folding kids table made everything easy to fold up and put away when not in use.
After college, I moved into my very first apartment: A little one bedroom place with barely enough room to swing a cat. My donated coffee table became my new workbench. As long as I kept it covered with a cheap table cloth while I was working on a kit, I never had to worry about ruining the table. Heck, even after I got married and my wife moved into my tiny apartment, I kept using that set-up whenever I worked on a kit.
Don't give up the hobby! You can still make things work.
