There are problems with the 2020 Olympic Stadium. It is supposed to be large and eco-friendly. But now it is too costly so it has to be scaled down. British-Iraqi architect Zaha Hadid had designed the stadium to be built in Tokyo for the games.
The original plan included geothermal energy by using recycled rainwater to cool down the building. The plan also would have had grey water being reused for either the plumbing or the landscaping.
Then there is the cost factor. It was estimated to cost 300 billion yen ($3 billion) which officials say is too much. No details have been released how the design will be scaled down but those in charge claim the approved design concept will be kept.
Construction is expected to begin next year.
