Tokyo Skytree

KIKUKAWA also took part in this iconic architectural project that was completed in 2011.
We worked with Nikken Sekkei from the start to carefully design, plan and execute this project.
The plan was to install our exterior and soffit panels 450m off the ground. Installation at this height was a KIKUKAWA first. A key element to consider was the wind-load of which was estimated to be up to 1 ton. Our Aluminium panels were rigorously tested by placing bags of sand that weighed 1 ton to see whether its physique or the structural integrity would be affected.
Half of the assembling process took place on the ground whereas the other half was done on the scaffolds set 450m off the ground. This along with installation difficulties or the re-fabrications of the panels required due to discrepancies in the structural beams measurements made this project a memorable and challenging for KIKUKAWA.
