This is the view out of the conference pavilion for the Vitra Campus, Tadao Ando's first building outside Japan. Tadao Ando wanted to integrate his pavilion harmoniously into the cherry tree meadow, which had grown for decades, with the aim of cutting as few trees as possible. To do this, he took aerial photographs and turned the building plan until only 3 trees had to be pruned at the end. I find this an impressive example of cautious architecture in harmony with nature. Ant it was above all about this one tree, which would certainly have been felled with the usual approach in architecture: the surviving tree.
