Gophers - New residential pattern, new residential choice. (Take one floor housing for example.) The roof of Gophers and the ground floor are at the same height, and it could make human and nature closer. You can directly see through the transparent facade to observe the underground living beings, the underground living beings could also observe us. Team TJJN explored a brand-new hollow floor with double layers to let the underground living beings get in, and you can just wait for the living beings to occupy the hollow floor. It will soon become a tiny community just beside your lovely house, all above entirely indicate the sense of time, the experience of time. You can also try to figure out that the earth, the mud which dug out while construction. It will be a great material for park construction.
