Alejandro Aravena: My architectural philosophy? Bring the community into the process

It was a complex problem, but with a simple solution — one that he arrived at by working with the families themselves. With a chalkboard and beautiful images of his designs, Aravena walks us through three projects where clever rethinking led to beautiful design with great benefit.
