In my studio/gaming/modeling room I had a fold-out gaming table installed. It’s pretty flush to the wall when folded, so it doesn’t make the small room feel cramped, yet it opens to a nice size. If I remember I’ll upload some photos in the afternoon.
(This being a temporary arrangement for you might make something you have to screw to the wall not work out, but you always can unscrew and take it with you to whichever new place you go)
