If you have not already discovered TED Talks, the online channel featuring short, insightful lectures by prominent people from all fields and walks of life about topics that interest them, I highly encourage you to take a visit, either to their YouTube channel or their homepage.

For those who don’t know: With the slogan “Ideas Worth Spreading”, TED began as a conference for people from the worlds of technology, entertainment and design (hence the acronym), but has since expanded to cover just about every conceivable topic. One of the principle outputs from the TED conferences, which take place in cities all over the globe, are the TED Talks, in which an expert in their given field must give an informative, entertaining talk in eighteen minutes or less.

Which brings me to this excellent example from Japanese architect Shigeru Ban, whose work is notable for using sustainable building materials such as cardboard tubes and paper. As well as their obvious usefulness in terms of providing temporary shelter and accommodation during humanitarian disasters, these principles can also be applied to longer term constructions, as Ban’s talk demonstrates:

 

I had no idea that it was conceivably possible to construct multi-story structures out of such materials, and much as I love watching the rise of the new steel and glass skyscrapers in my home city of London, it is wonderful to appreciate these radically different, more natural structures too.

Pushing the boundaries of possibility even further in another TED Talk, architect Michael Green proposes building safe, multi-purpose structures such as skyscrapers out of wood:

 

As Green says (and I am in no position to refute despite my love of the steel frame skyscraper):

“Every time I go into my buildings that are wood, I notice that [people] react completely differently. I’ve never seen anybody walk into one of my buildings and hug a steel or a concrete column, but I’ve actually seen that in a wood building, I’ve seen how people touch the wood. And I think there’s a reason for it. Just like snowflakes, no two pieces of wood can ever be the same, anywhere on Earth. That’s a wonderful thing.”

Definitely my best discovery of the day.
