Forest Portal is composed of many bows of local willow bent utilizing a lashed bamboo grid as a scaffold. This bamboo grid will be treated by soaking in sea water to prevent degradation and will last for 10 years. The Bamboo grid will serve as a climbing structure during this time and allow the shaping of auxiliary branching into a cubic grid. This deformation of the growth process creates an aberration in the flow of the forest, marking a transitory space.
