Husband built this kidney shaped stacked flagstone sandbox. It's approximately Perfect option for an area that is not level. The ground toward the tall grass in the picture is actually lower than the tallest end. This would be great for a firepit too!
Leave plastic animals in a bin outside (near the garden, next to the sandbox, next to a patch of trees, etc) -- when children go outside to play, they them and let their imagination.forward to playing outside
I like the store ideas and the ledge to sit outside. Also, like the bins for water play in the sandbox. The cover wouldn't withstand our windy environment. But would need a shade cover and a sandbox cover. Kona Sandbox with Canopy by KidKraft
