We all know that cardboard is an eco-friendly source of materials. You do a lot of things from cardboard and this include furniture pieces, art pieces, home decors, and even architecture. The packed cardboard pavilion is one of the great examples. Designed by students from ETH Zurich, Switzerland, Packed is the output of Min-Chieh, Dominik Zausinger, and Michele Leidi. With the help of the modern imaging software, the Packed was digitally designed. Cardboard cylinders of different sizes were connected together and the Packed cardboard pavilion was formed. How the cardboard were sourced can be a question, but what matters most is that it will decompose easily.
