Of course architects create huge 3D geometric spaces all over the world. A wonderful source of investigation for primary students.
The 2014 Pritzker Prize for Architecture went to Japanese architect, Shiguru Ban. He created the temporary Cathedral for Christchurch, New Zealand, after the 2011 earthquake – made from recycled equal length cardboard tubes, wood and glass. These provided quick and efficient construction and the cathedral is large enough to hold 700 people.
Paper tubes are fairly inexpensive and Shiguru has used them for disaster relief structures in Ahmedabad India, Rwanda and Kobe, Japan. Imagine what your students could create using cardboard tubes, just like this prize-winning architect.
