Diy patio in a rental home

Hey guys, I'm renting a home with a nice backyard. Grass all over the whole thing. Alive.

This is my second year and I haven't even been in the back yard cause it's just grass. I decided this year I'll do something

Is there any renter friendly ideas I can do to build a temp deck? I know the grass under will die, I'll replace or regrow it before I leave. I plan on being here at least another year. Have you guys done any quick decks? Any ideas I can do?
