This project is called a Pop-up Shelter.
It is currently installed at the 2015 Real Size Design Thinking exhibition. By combining stretchable fabric and FRP elastic rods, a soft enclosure is created. The fabric has pockets to contain the rods.
To make the form, the rods are first inserted into the fabric. Next, the fabric is stretched and the intersection points of the rods are secured in place with zip-ties. The geometry is flat in the beginning, but it becomes a 3D form after the intersection points of all the rods are fixed.
