While Heatherwick Studio enters an international competition for designing the new Terminal 5 at Changi Airport, Singapore, Safdie Architects' bio-dome that houses the world's largest indoor waterfall is on its way to completion. Although a formal announcement of the project hasn't been made, rumor has it that Heatherwick Studio will be tasked to create this massive building that will accommodate 50 million passengers per year and which will be in close relation to Safdie Architects' ecology-inspired project. The budget for the expansion is about $1.2 billion.
A high traffic area, Safdie Architects mixed-use 'Jewel' bio-dome offers a welcomed natural aspect to the busy and stressful ambiance of Changi Airport. From the inside, the spherical structure boasts a jungle-like setting that is only enhanced by the enormous indoor waterfall.
