The National Stadium is part of the hub, which also includes an indoor aquatics centre, multi-purpose indoor arena and water sports centre. The entire project will cost $1.33 billion, and more than half will go towards building the main arena.
At a media briefing yesterday, members of the Sports Hub consortium went into greater detail on its technical features.
Apart from the size of its record-breaking dome, the stadium's most striking feature is its retractable roof, which takes 25 minutes to open or close. It is made out of a lightweight material called ETFE, which is weather-resistant and blocks the sun's heat.
