“Big Furniture Like a Cave made of Soft Plastic Material:This is the award-winning project won the Grand Prize of Art in Container International Competition in Kobe Biennial 2011 in Japan. My idea is to hollow out the volume inside a container in order to build amorphous space like a cave. It is made of only plastic material (Polyolefin firing resin board). About 1000 sheets of the soft plastic material of 10-mm thickness were cut down in contour line form and were laminated like stratum. This is not only art but also big furniture. Because all the portions are soft like a sofa, and person who enter into this space can relax by finding the place suitable for the form of its own body.As The Nature-oriented Architecture:I am a great interest in nature especially the system of nature.Three years ago, my exhibition held in England. In the exhibition, a lot of experimental architectural projects and the execution works in each category that I obtained the inspiration from nature such as “Solar”, “Air”, “Water”, “Ground”, “Crystal”, “Biological”, “Flower” , and “Aurora” were exhibited.Because these aimed to approach “Nature” more closely, it was named “Nature-oriented Architecture”. And therefore, this “Artificial Topography” is the recent project of the Nature-oriented Architecture as “Ground” category.“
