In this project, Mur Mur lab continues to explore the spatial performance of simple geometries. Three perpendicular pillars support differently oriented rings and transfer the vertical load to ground. Three horizontal poles are connected to the trunk at different heights in order to resist the horizontal instability. With the interwoven colorful nylon tope, the sun light and the green color of trees render the site into an abstract painting. During its temporary existence, it hosted a series of small exhibitions. Also, it is a special experience of climbing up and down on the tree to see the show. It is a dress designed for the tree, as well as a gift for the lovely kids. The tree house gently embraces the tree in the air, just like the one in kids’ dream. It doesn’t take up much compact outdoor space and doesn’t block visitors’ sight of looking at Wutopia lab’s white house. The tree house is light and visually transparent. Kids climb up and down on the tree house. The white string net would be their bed if they feel tired. Their laughter can reach the ground and we catch it with happiness.
