Takashi Kobayashi is the mastermind creator behind Kusukusu, the largest treehouse built around a towering, 300-year-old camphor tree in Atami, Japan. Completed in March 2014, Kusukusu is the result of collaborative work between Kobayashi and Hiroshi Nakamura of NAP Architects for the Risonare Resort.

After 3D-scanning hundreds of points on the tree, the team created a steel trellis that threads throughout the branches, forming a support system that’s both architecturally sound and visually arresting. The most worderful thing is that the self-standing structure doesn’t touch the tree at all, leaving it unharmed and free to grow further.
