CNN’s Monita Rajpal walks the streets of Hong Kong with acclaimed structural engineer and designer Cecil Balmond. The man who brought to life some of the world’s most innovative structures opens up about his collaborations on the CCTV building in Beijing and London’s ArcelorMittal Orbit. Now a designer in his own right, Balmond reveals how his work strikes a balance between art and science and explains his passion for adding variety to a field dominated by regularity. Monita also discovers how Balmond’s technical knowledge could have been the key to his dramatic escape from the 2004 tsunami in his native Sri Lanka.
