We had an above ground pool growing up that my dad still maintains. Build a nice deck around it and lattice to grow vines up and it’ll look nice from window views.

As for leaves we put in some 8x8” posts and ran a wire across the length of the pool. Then rig up some shade cloth type materials to create an A to keep leaves out of the pool in fall.

That pool was the backbone of our birthday parties growing up (30+ years ago) and still going strong!
