This document contains summaries of four projects that explore innovative and sustainable approaches to architecture: 1) A five-story green wall in Paris incorporates over 200 plant species to transform a concrete wall into living architecture. 2) Conceptual renderings depict a future city where plants harness solar energy and cover the urban landscape. 3) A house in New Zealand is built on sleds so it can be moved during storms to avoid destruction from coastal erosion. 4) A cardboard cathedral was rapidly constructed in Christchurch, New Zealand after an earthquake using paper tubes, shipping containers and a lightweight skin to serve community needs.
