Japanese architect Ban Shigeru is contributing his expertise to help people who lost their homes in the devastating earthquakes in Turkey last month.
Ban is working with students at Shibaura Institute of Technology in Tokyo to make prototypes of temporary housing with materials such as cardboard tubes and wood panels. Those parts are available in Turkey and are designed to be easily assembled on site.
Ban wants to start installing the structures as early as May with the help of Turkish people he worked with back in 1999, when a major quake hit western Turkey.
He says he designed the shelters with improved insulation and durability so that they can be used on a long-term basis.
Ban says many people lost their homes and are still too anxious to sleep as aftershocks continue. He says those people will be able to feel safe in the shelters made with light materials because they will not hurt people inside if they collapse.
Around 230,000 buildings were heavily damaged by the tremors in Turkey.
Ban is known as "the cardboard tube architect of action" for the unique building materials he uses and his relief efforts in disaster-hit areas around the world. He won the Pritzker Architecture Prize in 2014.
