What happens to all the World Cup stadiums now that the big event is over? Brazil spent around $4 billion on the stadiums used this year, including four new stadiums that are unlikely to ever see much action again. In Brasilia, a $900 million stadium has 72,000 seats, but local football teams will probably draw crowds less than a tenth of that size. In the heart of the Amazon rainforest, a little-used stadium will cost $250,000 a month just to maintain.
One suggestion is to turn the Amazonian stadium into a giant jail. But two architects have a more positive idea: Why not convert part of the old stadiums into much-needed housing?
