Check out this amazing hidden underground pool! This is by far one of the coolest most extreme examples of innovative engineering I’ve seen. A pool that disappears under a ceiling of grass. Now of course, this isn’t exactly off grid, but it could give you some ideas on how to maximize the space in small yard. Imagine a garden growing on top. One need not make the cover slide under the deck, it could simply move. A garden that hides a pool.
It also doesn’t have to be a pool. It could cover a hidden root cellar, basement, or the entrance to an underground bug-out bunker. The possibilities are endless.
