This news special, on Chinese architect Zhang Yue, presents the sort of tell-me-more story you usually see on 60 Minutes. This late-to-architecture entrepreneur has made a fortune, and lots of waves, with his brazen approach to constructing environmentally friendly high-rises. He builds them of steel and glass in pre-fab form, with construction taking place so quickly that his Mini Sky City showpiece, a 57-story office and residential building housing 4,000 people and 800 apartments, was built from foundation to roof in a total of 19 days. What’s wrong with that? And what’s right? This BBC World News special asks those questions, and more.
