This is a wall which made a dream come true for those who love nature but hope to have a personal privacy.
Thanks for the newest Japanese high-technology recently brought into the world, now it is possible to create a wall integrated tree or a tree integrated wall. Cost? No problem, not particularly high compared with ordinary walls. Only issue you might need to consider is time. It may take some ten years until both the tree and the wall get emerged together to make an integrated wall!
