Richard Seymour worked with 'Design for Need,' a shelter for UNESCO and worked on it to perfection, it was easily deployed, cheap and effective. When received by locals, they ripped it apart and built homes with their traditional method. The world is not a ‘one answer for all’ and failure to listen and watch those on the ground results in designs that do not work.
“If your job is to meddle in creating the future, step carefully, or do something less dangerous.” Richard Seymour
Another good example is Brian Forde’s bike with phone access in Guatemala powered by pedal power. http://www.pedaleadas.com/ It met several impressive keywords of social enterprise from mobility to reach gaining media attention throughout the western world. However the project failed enormously. Locals did not want to make phone calls to chat with their pals or ask who wanted to go see a film, they wanted to spread the news of death or spread money to family, relatives and friends whom had left the country. The bike for the public square did not address the required privacy, important criteria, The project failed.
