A venue like no other
Central to the park is the 50,000-seat Kai Tak Stadium, dubbed as the ‘Pearl of the Orient’. Designed to address Hong Kong’s humid sub-tropical climate, the stadium features one of the world’s largest retractable roofs and a flexible pitch surface, allowing the venue to host a variety of events in any weather.
The retractable roof, weighing nearly 4,800 tonnes, operates quietly and can open or close in just 30 minutes using advanced mechanisms similar to railway technology. To support this massive roof, Arup engineered a bespoke structure with four mega trusses spanning between 150m to 180m, anchoring on four bearing-free reinforced concrete towers at the corners to ensure an unobstructed view for every spectator. Building information modelling (BIM) was fully adopted to optimise the structural design, ensuring constructability and minimising steel use.
Given the stadium’s proximity to residential areas, the retractable roof is acoustically sealed when closed, using sound-proof barriers and heavy cladding panels to dampen low-frequency sound, making the stadium one of the most efficient soundproofing sports facilities in the world.
