My architectural philosophy? by Alejandro Aravena

Alejandro Aravena's architectural philosophy is to "bring the community into the process." Ten years ago, when tasked with building housing for 100 families in Chile, he found inspiration in favelas. Instead of small units in large buildings, he designed flexible "half-homes" that each family could expand. This complex problem found a simple solution through direct collaboration with the families themselves.

Aravena showcases three projects where clever rethinking led to beautiful, beneficial design. Learn more at Alejandro Aravena's website, or follow TED on Twitter and Facebook.
