What should I do with my basement? It has a couch in it, a litterbox and nothing else. I don't know what to use it for. I don't have children, just cats. It has a closet with laundry, then a tinier creepy crawl space I use for storage. It is finished, heated and has carpet. I don't need it to store things, I have two spare bedrooms for guests. I want to do something fun, not sure what? It's L Shape; it's probably 15 feet long and about 6 feet wide so not super big.
