 ■Features
 A tree house was constructed in an unused villa area, serving as accommodation and a BBQ area.
 Entering the treehouse across the suspension bridge, which takes advantage of the difference in elevation of the land, feels like an adventure every time, and the host tree, a red pine, runs through the inside of the treehouse, allowing you to feel the changing wood grain of the seasons, and you can fully experience nature even while indoors.
