The japanese pavillion at expo 2000 in Hannover

My first post (excluding my own projects) on my blog will be my perhaps all time favorite architectural design; the japanese pavillion at expo 2000 in Hannover by japanese architect Shigero Ban. His lifelong exploration of paper as structural material is inspiring and has created new standards for paper architecture. 
The pavillion was designed in collaboration with Frei Otto and is a gridshell covered by a membrane. The geometry is advanced but the structural elements and connections are designed with a simplicity which is absolutely beautiful. From my point of view the pavillion is a climax of all the earlier paper structures designed by Shigero Ban. I can highly recommend studying Bans work and will recommend the book "Shigero Ban" by Matilda McQuaid.
