"There are a lot of resources given by nature for free -- all we need is our sensitivity to see them and our creativity to use them," says architect Anna Heringer. Heringer uses low-tech materials like mud and bamboo to create structures from China to Switzerland, Bangladesh and beyond. Visit an awe-inspiring school, an elegant office and cozy social spaces -- all built from natural materials -- in this delightful talk.

"In this video, Anna Heringer speaks about how she learned to work with the materials around her, making building more about the process and the power of creating together and why beauty is a synonym for sustainability.
