Around a thousand containers are being used in the construction of what is described as the world’s first demountable soccer stadium.The 40 000-seat venue is slated for completion in 2020 and will be located in a 450 000- square-metre waterfront site on Doha’s shore, where the use of shipping containers as one of the main building blocks will echo the nearby port, according to the designers.It is being built using modular building blocks, each containing removable seats, concession stands, toilets, offices and other rooms that go into a stadium.The use of shipping containers has reduced its carbon footprint.
