The Singapore Sports Hub sits on a 35 acre site and its designers were local, DP Architects. The heart of the Hub is the National Stadium with the dome measuring 312m in diameter; it beats the previous title holder of the biggest dome structure, the Texas Cowboys Stadium, by  37m (roughly 10%).

The stadium was designed with a roof that can be retracted, while the interior of it boasts a layout that is flexible. This means it can play host to soccer, athletics, cricket or rugby and the layout can be changed in as little as 48 hours.

The Hub is also home to other sporting venues, including a large aquatic centre which offers seating for 6,000 people along with an in-door arena with seating for 3,000 people. There is also a water park, facilities for rock climbing and a retail area of 41,000 sq m. The Singapore Sports Hub offer visitors a museum and library along with a visitors centre, plus there is office space of around 18,000 sq m.

The water centre offers numerous activities; these include kayaking and canoeing as well as many other smaller areas of the Hub for activities such as cycling, jogging and beach volleyball.

DP Architects designed the Singapore Sports Hub with emphasis on visitor comfort as they wanted to ensure that fans watching the sporting events were kept cool. So with this in mind they built the centre to get the most from the prevailing winds along with planting lots of areas of greenery.

Phoenix Solar, another local firm, got the contract for installing the solar array on-site. This has measurements of 7,000 sq m and offers all the energy needed for the cooling system within the stadium. DP Architects said that the solar array generates enough energy for a 60% reduction in energy usage in comparison to a stadium that cooled by conventional means.
