Dubai Frame: The city isn’t just about looks – although it does pretty well in that department all right. Dubai’s 150-metre landmark frame is the biggest picture frame on Earth and offers a lovely view of the city. But its origin story is even more interesting than the vistas it offers. The structure, made using more than 9,900 cubic metres of reinforced concrete, 2,000 tonnes of steel and 2,900 square metres of laminated glass, was inspired by the ‘golden ratio’. This ratio, 1.618, is considered an ideal structural balance by architects. The Great Pyramid of Giza is one of the early examples of A building that used this ratio.
