Man Builds DIY ‘Hidden Pool’ In His Backyard That Disappears Under a Grass-Covered Top When Not in Use

Israel-based engineer Gil Klar wanted a pool in his backyard, but his wife wanted to keep the yard as a play area. As a compromise, in 2013 Klar built himself a “hidden pool,” complete with a retractable, synthetic grass-covered top that allows the pool area to double as an ordinary lawn. This making-of video depicts the entire build process.
