How making houses out of paper changed aid agencies’ disaster response
Japanese architect has designed emergency shelters for victims of Nepal’s earthquakes, Typhoon Haiyan and more, and in doing so prompted humanitarian workers to forgo cookie-cutter solutions and adapt their responses to match local conditions
After twin earthquakes in April and May claimed 9,000 lives and left vast swathes of Nepal in ruins, survivors worried that if they reused the brick rubble, they would end up with the same vulnerable, seismically unsound structures. Japanese architect Shigeru Ban – who helped bring global attention to humanitarian architecture and continues to influence fellow architects and disaster-relief workers – devised a solution.
“Each disaster is different, so I have to go there to find out the particular problems to solve,” says 58-year-old Ban, who built paper emergency shelters in Haiti after the 2010 quake and the Philippines after Typhoon Haiyan two years ago. “The solutions are always dependent on the climate, economy and materials available locally. And also how long they must stay. All criteria and solutions are different.”
The prototype for his latest humanitarian housing project in Nepal consists of standard timber door frames joined together and reinforced with plywood. The frames are filled in with brick rubble, and the roof is covered with a plastic sheet and thatched for insulation.
The resulting structure is strong enough to meet Japan’s stringent earthquake standards, he says. “I’m hoping people will copy my design. If we make 20, some other NGO might make more. I’m encouraging people to copy my ideas. No copyrights,” Ban says, noting he always tries to enlist the help of his houses’ future inhabitants. “If they’re involved in the construction, if the structure needs maintenance, they will know how to do it themselves.”
Aesthetics are also very important. “The government is not usually looking for beauty but I think that beauty and comfortablity is taking into account people who have suffered mentally and physically after a disaster.”
Ban, winner of the 2014 Pritzker Prize, architecture’s top award, has also built shelters for Rwandan refugees in 1994, Sri Lankan survivors of the 2004 tsunami, and victims of major disasters in Japan.
Fellow Pritzker prize winners Thom Mayne and Frank Gehry teamed up with Ban to work with actor Brad Pitt’s Make It Right Foundation, a non-profit group set up in 2007 to help rebuild New Orleans’ Lower 9th Ward after Hurricane Katrina.
Ban’s work has pushed aid agencies to take on challenges differently, says Brett Moore, a shelter, infrastructure and reconstruction adviser for World Vision International.
“Ban’s approach to humanitarian work prompts the entire humanitarian community to think outside the box, to reject generic and inappropriate responses to vastly different contexts, and to approach the work with individuality and creativity,” Moore adds.
His emphasis on reusing materials also fits with a broader trend, as aid agencies try to rebuild sustainably after disasters. “There’s a lot more concern now than there has been in past decades on reuse and recycling. That is something for us as humanitarian agencies to look into,” says Sandra D’Urzo, who works on shelters and settlements for the International Federation of the Red Cross in Geneva.
While Ban says he enjoys working on grand projects commissioned by privileged people, he also wants to help people who have lost their homes, and is encouraged that many architects have followed in his footsteps.
After the massive 2011 earthquake and tsunami ravaged the Japan’s Tohoku region, Ban noticed an increase in architects on the ground compared to the aftermath of the Kobe quake. “When I was working in Kobe in 1995, there were no architects in the disaster area, but in Tohoku after the earthquake, there were so many,” he said.
“I’m very happy that now, even young architects and students are interested in what I’m doing, which was not the case 20 years ago.”
In Tohoku, Ban’s three-storey temporary housing has proved so popular, its residents are reluctant to leave. “That is such a wonderful compliment for me. I had to try to persuade government to make my housing the standard because we need solutions for the next disaster. They now have a better understanding than before but had to see a successful example first. I showed them that the size and cost is exactly the same as the government housing but the solution is so much better.”
After the quakes hit Nepal, Ban says Nepali students in Tokyo and his friends around the world hastened to raise funds for his project. “It moved rapidly at first, but not as rapidly as I wished because of the local situation,” Ban says, referring to Nepal’s fuel shortage.
Ethnic Madhesi groups, protesting that Nepal’s constitution adopted in September marginalises them, have been blocking trucks from India. The blockade has led to acute shortages of fuel and medicine. Ban is used to adapting to harsh local conditions when building for disaster victims, and in this case he had to tweak his original prototype.
Instead of constructing the roof frame with his signature cardboard tubes – as he used after the quake in Christchurch, New Zealand, for a cardboard cathedral – the fuel shortages led Ban to make trusses from timber, until factories are up and running and cardboard can be procured again.
His initial goal to build 30 homes in Phatakshila in the Sindhupalchok district in central Nepal in the coming months is moving forward.
Whenever possible, he uses locally available materials, and prefers renewable resources such as timber and paper to concrete and steel. “The strength of the building itself has nothing to do with the strength of the material. Even a concrete building can be destroyed by an earthquake very easily, but a building made of paper sometimes cannot be destroyed by the earthquake,” he says, sitting in a chair of his own design made of cardboard rods as solid as wooden dowels.
Although his humanitarian work has allowed Ban to further explore the use of unusual materials and structures, it is clear that his work is dictated not by a desire for innovation but by a passion for frugality. “My parents were very strict – when I left my room I had to turn off the light and not leave a single piece of rice in my bowl. It is important people do not waste. I can’t believe we import Evian water from France. We should stop that kind of waste.”
Ban shrugs off any suggestion that building with paper or cardboard is revolutionary. “It is just normal recycled paper. They are not new materials. I simply look for a different meaning and function from existing materials but it is nothing special. Paper is like wood so as long as I can prove it is safe, I can get permission to build with it.”
