Instead of concrete, how can I make a patio floor?
Slate, bluestone, etc.
We bought our house last year and apparently the previous owners didnt want the dirt car port. They laid stepping stones around the whole area. Of course they were elderly and all the stones were unlevel but I'm in the process of trying to get them all level it's actually kinda cute.
There are dozens of choices of pavers at your local stores. Home depot and Lowe's have many selections right now. Some are hravy, some aren't.
You can do a just above ground level deck floor.
