And has China just built the best spiral staircase ever?   In this episode, Dezeen features editor Nat Barker and architecture reporter Amy Peacock discuss the (literal) launch of the Tesla Roadster, which set the internet alight with footage of its acrobatics.   Then, they consider the architectural significance of the newly completed Shanghai Grand Opera House.   *Dezeen Weekly artwork is by Simon Volt.
