When asked to build housing for 100 families in Chile ten years ago, Alejandro Aravena looked to an unusual inspiration: the wisdom of favelas and slums. Rather than building a large building with small units, he built flexible half-homes that each family could expand on. 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.
In 1967, Moshe Safdie reimagined the monolithic apartment building, creating “Habitat ’67,” which gave each unit an unprecedented sense of openness. Nearly 50 years later, he believes the need for this type of building is greater than ever. In this short talk, Safdie surveys a range of projects that do away with the high-rise and let light permeate into densely-packed cities.
Facebook’s “like” and “share” buttons are seen 22 billion times a day, making them some of the most-viewed design elements ever created. Margaret Gould Stewart, Facebook’s director of product design, outlines three rules for design at such a massive scale—one so big that the tiniest of tweaks can cause global outrage, but also so large that the subtlest of improvements can positively impact the lives of many.
In the center of Caracas, Venezuela, stands the 45-story "Tower of David," an unfinished, abandoned skyscraper. But about eight years ago, people started moving in. Photographer Iwan Baan shows how people build homes in unlikely places, touring us through the family apartments of Torre David, a city on the water in Nigeria, and an underground village in China. Glorious images celebrate humanity's ability to survive and make a home -- anywhere.
How do we solve the problem of the suburbs? Urbanist Jeff Speck shows how we can free ourselves from dependence on the car -- which he calls "a gas-belching, time-wasting, life-threatening prosthetic device" -- by making our cities more walkable and more pleasant for more people.
In this funny and thought-provoking talk, Janette Sadik-Khan, transportation commissioner of New York City, shares projects that have reshaped street life in the 5 boroughs, including pedestrian zones in Times Square, high-performance buses and a 6,000-cycle-strong bike share. Her mantra: Do bold experiments that are cheap to try out.
Months after he was born, in 1948, Ron McCallum became blind. In this charming, moving talk, he shows how he is able to read -- and celebrates the progression of clever tools and adaptive computer technologies that make it possible. With their help, and that of generous volunteers, he's become a lawyer, an academic, and, most of all, a voracious reader. Welcome to the blind reading revolution. (Filmed at TEDxSydney.)
A third of the world watched live as the World Trade Center collapsed on September 11, 2001; a third more heard about it within 24 hours. (Do you remember where you were?) So exhibits at the soon-to-open 9/11 Memorial Museum will reflect the diversity of the world's experiences of that day. In a moving talk, designer Jake Barton gives a peek at some of those installations, as well as several other projects that aim to make the observer an active participant in the exhibit.
"An advanced city is not one where even the poor use cars, but rather one where even the rich use public transport," argues Enrique Peñalosa. In this spirited talk, the former mayor of Bogotá shares some of the tactics he used to change the transportation dynamic in the Colombian capital... and suggests ways to think about building smart cities of the future.
What would a city designed for the blind be like? Chris Downey is an architect who went suddenly blind in 2008; he contrasts life in his beloved San Francisco before and after -- and shows how the thoughtful designs that enhance his life now might actually make everyone's life better, sighted or not.
When TED Fellow Xavier Vilalta was commissioned to create a multistory shopping mall in Addis Ababa, he panicked. Other centers represented everything he hated about contemporary architecture: wasteful, glass towers requiring tons of energy whose design had absolutely nothing to do with Africa. In this charming talk, Vilalta shows how he champions an alternative approach: to harness nature, reference design tradition and create beautiful, modern, iconic buildings fit for a community.
Most of us want to do the right thing when it comes to the environment. But things aren’t as simple as opting for the paper bag, says sustainability strategist Leyla Acaroglu. A bold call for us to let go of tightly-held green myths and think bigger in order to create systems and products that ease strain on the planet.
