Zaha Hadid Architects has released this movie detailing its design for the scrapped Tokyo 2020 Olympic stadium, which it describes as "the only way to achieve value for money in the market". The film, which is over 20 minutes long, explains the decisions made during the two-year-long design process that lead to the current proposal, which was dropped last month by Japanese prime minister Shinzo Abe citing spiralling costs. It also argues that starting again with a new design will not save the Japanese taxpayer any money so it could end up costing more in the long term, and the firm urges the government to reconsider its decision. "The design should be seen as the only way to achieve value for money in the market," says Zaha Hadid Architects in the film. The estimated cost of the Japan National Stadium rose to 252 billion yen (£1.3 billion) last year and has seen opposition from many Japanese architects. The government has now decided to start again with a new design. But the London-based firm claims the increase is due to a 25 per cent rise in costs across Tokyo's construction market over the past two years. In the film, it says it will be impossible to create an equivalent stadium for less money.
