Imagine a city made out of wood, suspended above a forest. Or a building grown from crystals. Or imagine houses that double as a protective wall against desert sands and have bacteria reprogrammed to construct those houses for us.

He unveils his designs for the upcoming material ages as the Concrete Age shifts towards a new Timber Age and, ultimately, the Materiomic Age.
