How long and where did I build?<br /><br />I have been working very hard with my 2 friends for about 100 Days to completely build, This underground hut is in a very small private jungle in California (United States), We did it together with three people (2 people are builders and one person he is cameraman)<br /><br />How large is it?<br /><br />Underground Hut Dimension: Depth 5m, width 18m, height 7m, I knew the most of viewers it hard to believe but it was really 100% handmade with tools in the video! If you have any ideas, please leave a comment below my video.<br /><br />We are very happy for your constructive feedback. We hope all of you enjoy our videos!!
