Singapore’s huge SportsHub stadium designed by DP Architects was just declared the largest free-spanning dome structure ever built! The 55,000-seat stadium stretches more than 1,010 feet across its widest point and can host all types of games-from cricket to rugby, while the entire development features water parks, skate parks and even space for canoeing and kayaking.
The stadium features a retractable roof that spans 1,017 feet. The dome’s key characteristic is that it uses one-third of the steel weight per square meter compared to other large span structures of the same scale. It is air-cooled for comfort and designed with a movable roof and retractable seating to support the widest range of sports and leisure events throughout the year. It can host athletics, football, rugby and cricket and can convert from one mode to another within 48 hours.
The stadium is surrounded by a mix of sporting, community and leisure venues and spaces. Its masterplan includes sequences of interconnected public spaces that are scaled for everyday use and major events. It has easy access to the Mass Rapid Transport (MRT) system, adjacent expressways and road network.
