Dean Landy is an Australian architect whose work has taken him around the world, from building Lego cities on a pool table to building schools and homes in Africa.
He's also the founder of One Heart Foundation, an organization that aims to alleviate poverty by building and operating schools, children's homes, and skills training centers in developing nations, Fast Company reports.
Landy's "defining moment" was volunteering in the Himalayas, he says.
"Sitting there watching these doctors in this incredible mountaintop village, I just wrote a note to myself that if I'm not doing something in 10 years' time from now to improve the lives of others then I'm a failure," he says.
"So it's really just working with a vernacular that the local builders can work with because our approach at One Heart is not about having westerners on the ground permanently."
