PAM Sarawak Chapter and INTODESIGN Lab conducted a ‘building’ workshop for primary school children titled ‘The Cardboard City Challenge’. The ‘construction’ of the City started on the 3rd to the 6th of October, at BORNEO 744. 240 primary school students from 12 local schools took part in crafting and building cities of their own imagination. They were guided by the 30 local student volunteers. The final ‘Cardboard City’ was more than 400 sq.m. in area. Over the weekends after the official opening, it was recorded 1,200 people have visited the event. Generally, we hope to inspire young minds through spatial experience; we hope that they gain satisfaction in building with their hands and we hope they take away lessons about recycling, team work, problem solving, and become better creative thinkers and doers.
